ABSTRACT
The creation of mechanical devices driven by artificial intelligence (AI) is a huge step forward in rehabilitative medicine. These devices will make it easier for people who have lost limbs to move around and give them real-time brain control. This study paper looks into how AI technologies can be used in artificial limbs to make the user experience smooth and natural. Machine learning techniques are at the heart of our method because they read neural data straight from the user’s nervous system. This lets the device react in real time to the user’s free muscle movements. The study is mostly about making brain connections that pick up electrophysiological signals. These signals are then handled by advanced AI models to figure out what movements are meant to happen. After that, the artificial arms make these moves with a level of accuracy and response that is very close to how real limbs work. We also talk about the creation of feedback loops that let people get sense information from the device, which improves their ability to feel touch and body space. Our method uses a diverse approach that combines robots, neuroscience, and biotech. AI is the key that connects these fields into a system that works well together. Preliminary tests have shown that speed and accuracy of artificial control have gotten a lot better, making it much easier on users’ bodies and minds. Also, patient feedback shows that the device is more comfortable and easy to use, which suggests that it has a higher chance of being adopted. This study not only pushes the limits of medical engineering, but it also shows promise for helping amputees regain their freedom and quality of life.

INTRODUCTION
Putting artificial intelligence (AI) into replacement devices is a big step forward in medical technology. It will give people who have lost limbs incredible improvements in their ability to move and control their devices in real time. This paper describes a new way to make prosthetics that are driven by AI. These prosthetics will not only improve the physical skills of amputees, but they will also try to recover the natural functions of lost limbs through advanced brain connections. As technology continues to change the way healthcare is done, the need for better replacement arms has grown. Traditional prosthetics are basic devices that can replace lost limbs, but they don’t always have the smooth movement and fine detail of natural limbs. These restrictions can make it hard for people to go about their daily lives, causing them to have less movement, feel pain, and need a long time to get used to their new surroundings. With the rise of AI, however, there is a chance to completely change this field by creating devices that can learn and adjust to the user’s unique movement habits and tastes, making the experience more natural and easy to understand. Our study is mostly about using machine learning methods to figure out what nerve signals coming from the missing limb’s nervous system mean.(1) AI programs can use those indicators to make the device circulate in complicated approaches which can be controlled through the consumer’s very own mind impulses. This efficiently connects what someone wants to do with what a device does. The neural hyperlink, which connects the AI gadget to nerve ends in the missing limb, makes it viable to properly bet and perform desired actions. This procedure includes constantly collecting and analysing big quantities of records. Including systems for experience input is any other critical part of our growth. those methods let the person the use of them get actual-time physical records about their surroundings, like roughness, warmth, and pressure, that’s necessary for complete limb use. Sensory enter now not simplest improves how the man or woman the use of the device interacts with their environment, however it also makes it easier to govern and safer by means of letting the man or woman trade their grip power and walking stride as the conditions trade.(2) To get these consequences, our approach combines a number of crucial technologies, together with advanced sensor arrays, strong records processing devices, and motors that reply in no time. The physical symptoms are picked up through the devices, and AI then turns them into specific actions.(3)
This technology gives human beings extra freedom and independence, and the prosthetic limb may additionally even make it less complicated for them to think because it acts greater like a natural a part of their frame. Similarly, our take a look at method consists of running collectively with people from robots, neuroscience, and biology. Running together is important for solving the problematic troubles of making prostheses that now not most effective does their activity but also are at ease and long-lasting for normal use. We use user feedback loops and repeated trying out to ensure that our fashions are better and meet the wants and needs of stop customers.(4) In the progress made in this paper on AI-powered limbs now not best makes it simpler for amputees to transport round and be unbiased, but it additionally sets a new popular for how AI have to be utilized in scientific gadgets. These superior devices make real-time brain control feasible, which is a huge step closer to greater customized and adaptable fitness care. As time is going on, chronic enhancements in AI and a better knowledge of the way neurones work will honestly open up new alternatives for artificial technology, with a view to exchange the lives of thousands and thousands of people around the world who have misplaced limbs. This observe lays the foundation for more studies and development in this interesting area, with the intention of creating prosthesis generation greater beneficial and satisfying for users in approaches that have never been seen before.

The progress made in AI-powered limbs is based on an extended records of examine from robots, organic engineering, and artificial intelligence. Within the search for better motion and real-time brain control in prosthetic devices, many new thoughts were recommending. Everyone has delivered to the complexity of contemporary prosthetic era. This component talks about crucial development and linked works that assist us recognize and body our take a look at. Within the beyond, synthetic technology becomes primarily approximately mechanical systems that did not have brain interaction or feel input. Considering that era has stepped forward, however, the attention has moved to creating greater complex structures that paintings like natural limbs.(5) One important early step forward in AI-powered prosthetics turned into the usage of myoelectric prostheses, which pass limbs through the usage of electromyography (EMG) records from muscle tissues that is nevertheless there. By the use of electrical data from the consumer’s body in the manipulate systems, these devices had been a big step up from implants that were handiest mechanical. extra recent examine has built in this work by using searching carefully at how system getting to know strategies may be used to better understand EMG signals and make synthetic devices greater sensitive. As an instance, professionals have used unique methods, like support vector machines (SVM) and neural networks, to better separate those information into separate movement instructions. these research show that system gaining knowledge of is probably capable of shorten the time between what a consumer needs and the way a device responds, making the experience greater natural for the user.(6)
Lots of work has also long past into making direct neural connections (DNIs), which connect prostheses immediately to the apprehensive machine. Those gadgets get around the problems with surface EMG via without delay having access to mind alerts. This offers loads greater control enters and lowers the noise from outside the body. Implanted probes that pick up alerts instantly from the mind were utilized in a ground-breaking examine to reveal that DNIs should permit human beings manage synthetic limbs with simply their thoughts. This approach has no longer most effective made artificial fingers extra useful, but it has also made it less complicated to personalize them for anybody based totally on their particular mind patterns.(7) A whole lot of interest has additionally been paid to sensory feedback systems. Conventional implants don’t provide you with any bodily input, which makes it difficult to absolutely feature. As a recent step forward, bodily sensors had been added to artificial palms. Those sensors send messages returned to the person’s mind through the same neural paths which might be used for motion. This sense information is very important for jobs that need to be done precisely, like moving around on rough ground or handling fragile items. Also, creating flexible learning systems for limbs is a new and interesting area of research.(8) In a way similar to how predictive text works on smartphones, these systems use algorithms that keep learning from the user’s habits and tastes over time. These adaptable systems can fine-tune how they react based on the data they collect. This makes it easier to customise the prosthesis to the user’s specific moving habits and way of life.(9)
Along with progress in technology, a lot of work has been done on the moral, psychological, and social effects of implants driven by AI. Researchers are looking into how these devices affect the users’ quality of life. They are looking at both the physical and mental health effects of using them. Studies have shown that amputees’ self-esteem and freedom can improve significantly when their devices are more sensitive and easy to use.(10) This shows how important user-centred design is in the development of prosthetics. All of the linked work in AI-powered prostheses gives our study a strong foundation. Each study adds to our understanding of how to solve the technical problems that come up when using AI in biological applications. This will allow people to have more freedom, movement, and interactions with the world around them. It is important for people from different fields to keep working together in this field so that AI can be fully used to improve artificial technology and make sure that these high-tech gadgets not only copy human skills but also go beyond them.

METHOD
Description of the AI Technologies Employed
Artificial intelligence (AI) technologies are used to make improved prosthetic devices, mostly by making it easier for the user to connect with the prosthesis. In our method, AI is the main technology that makes it possible to change and perform moves that look like they were made by a person in real time. We use a variety of AI methods, such as fuzzy logic systems, neural networks, and reinforcement learning. Based on information from brain and myoelectric sensors, neural networks are used to find patterns and make decisions. This lets the device figure out what the user wants to do by looking at the electrical patterns that are made when muscles work. Reinforcement learning methods are used to make the prosthetic work better over time by learning from the user’s experiences and making the device work best in different situations. Fuzzy logic is a way to deal with unclear and changing sensor inputs, as shown in figure 1. This makes sure that prosthesis moves are smooth and reliable even when the operating conditions change. These AI technologies work together to make a system that not only moves like a person’s limbs, but also learns and changes based on the person’s tastes and physical traits.
Figure 1. Overview of AI-Powered Prosthetics System
Explanation of the Neural Control Interface
Our AI-powered prosthetics have a brain control interface that is meant to connect the user’s nerve system directly to the artificial piece. To record brain data, this interface uses high-tech signal processors and wire arrays that are carefully placed on the missing limb. The hardest part is correctly translating these signals, which are often weak and noisy, into orders that the device can follow. To fix this, we use high-resolution sensors along with signal enhancement and filtering methods to make the brain cues clearer and more reliable. These signals are sent through an interface that uses a processor that is driven by machine learning to turn brain patterns into specific moves. This translation is based on computer programs that have been taught to recognise and understand different mixtures of brain signals that represent different human goals. Because this interface is so advanced, it’s possible to make a prosthesis that is very sensitive and can do difficult jobs that need fine muscle control, like typing or playing an instrument.
Details of the Machine Learning Algorithms Used
Machine learning algorithms are a key part of making AI-powered devices work. They turn sense and brain inputs into precise, controlled actions. Here, I’ll explain how to use these algorithms step-by-step, explaining how each one works with the others to make the replacement system work:
Step 1: Data Preprocessing
· The goal is to get the sensor data ready for machine learning analysis by cleaning and preparing it.
· Sensor Data Collection: Get raw data from the nerve sensors and EMG sensors that are connected to the missing limb.
· Noise Filtering: Use digital filters to get rid of noise and improve the signal quality, which is very important for correctly interpreting signals.
· Normalisation: Make the range of sensor outputs the same so that all inputs are treated the same in the next steps of processing.
Step 2: Feature Extraction:
· The goal is to get useful features from the already-processed data that can be used to predict movement.
· Windowing means dividing the ongoing sensor data into frames, or windows that are easier to work with and analyse.
· Figuring Out Features: Find statistical and time-frequency patterns in each window, like mean, variance, and power spectral density. These help to tell the difference between different kinds of brain signals or muscle movements.
Step 3: Model Training
· The goal is to teach machine learning models how to find the connections between sensor readings and specific moving directions by using the features that were taken.
· Training Process: To train the models, use a labelled dataset where each input feature set is linked to a known moving order. To do this, the settings of the programs need to be changed to reduce the number of wrong predictions.
· Cross-validation: Use cross-validation methods to make sure the model works well with different sets of data and doesn’t become too perfect.
Step 4: Movement Prediction
· Objective: Use the learnt models to guess the planned movement based on fresh sensor data.
· Real-Time Processing: As new sensor data comes in, it should be fed into the learnt models in real time to figure out what the user wants to do with their movement.
· Classifying Movement: Use the SVM or neural network’s output to sort the sensor patterns into clear orders, like “raise your hand” or “close your fist.”
Step 5: Making control signals
· Objective: Turn the expected movement orders into real information that the artificial devices can use.
· Signal Mapping: Map the movement order from the prediction step into specific data that can tell the artificial limbs motors or actuators what to do.
· Actuation: Send these control messages to the artificial hardware so that it can move in the way you want it to.
Step 6: Feedback Integration
· Objective: Add sense input to improve movement expectations and make it easier for the user to handle the prosthesis.
· Feedback Loops: Set up ways for the person to get physical or other sense data from the device, which should feel like their original arm.
· Adaptive Learning: Make sure the system changes to meet the needs of the user and the situations around it by using feedback to keep the machine learning models up to date and better.
Step 7: Continuous Learning and Updating
· Objective: Keep adding new data to the model to make it work better and be more flexible.
· Ongoing Training: Retrain the machine learning models on a regular basis with new data gathered during use to include a wider range of situations and make the system more accurate and quick to react.
· Performance Monitoring: Keep an eye on how well the methods are working and make changes as needed based on what users say and how well the system works.
· This organised, step-by-step process makes sure that every part of the machine learning chain works at its best to improve the usefulness and response of AI-powered devices, giving users a more natural and intuitive experience in the end.
Implementation of Sensory Feedback Mechanisms
Adding sensory input systems to our prosthesis is a key part of giving the person back their feeling of touch and proprioception. We put touch sensors in the artificial arms that pick up on things like feel, warmth, and pressure that happen when the body interacts with its surroundings. This sense information is turned into electrical signals that work like natural input from a biological leg. These signals are then sent back to the user’s nervous system through transcutaneous electrical nerve stimulation, or TENS. Microcontrollers in our system handle the sensor data in real time and figure out the right return messages so that this can happen. For jobs that need fine control, this input is very important because it tells the user how to change their grip strength, balance, and moving speed. The sensing loop in the device makes it easier for people to do difficult or delicate jobs with more trust and accuracy.
Data Collection and Analysis Procedures
The way we gather and analyse data is meant to make the device work better and make the user experience better all the time. We collect data in a number of different ways, including from sensors built into the prosthesis, user comments, and observations made from outside the body. Sensor data is collected during different tasks to train and improve AI models. It includes brain signs, muscle movement, and physical feedback. Interviews and surveys are used to get feedback from users on things like comfort, usefulness, and functioning. This qualitative data is very important for figuring out how to make the prosthesis even better. We also use film recordings and motion capture technology to look at how the device moves while it is being used. This gives us a full picture of how it works in real life. Data analysis includes both real-time processing to make changes right away and long-term analysis to see how things are getting better and change the machine learning models as needed. We use statistical methods and machine learning techniques to look at the data and find trends that show which exchanges are working well and which ones need work. This organised method makes sure that our devices not only meet, but also go above and beyond what users want and expect.
System design
Hardware Components: Sensors, Actuators, and Other Electronics
There are important hardware parts in AI-powered prostheses that make these high-tech gadgets work and be effective. Sensors, motors, and different kinds of electrical systems that handle data processing and control make up the main parts.
· Sensors: A lot of sensors are used to pick up bodily signs like nerve impulses and muscle movements. Some types of sensors are neural sensors that pick up information straight from nerve ends and electromyography (EMG) sensors that pick up electrical activity made by skeletal muscles. Inertial measurement units (IMUs) give information on the position, motion, and rotation of the limbs.
· Actuators: Actuators make it possible for the prosthesis to move. They need to be strong and accurate, and to move like real arms, they often use electric motors or hydraulic systems. When picking an actuator, you need to think about how much force and accuracy you need, as well as the movement you want to copy, like walking or holding.
· Other electronics: Power sources, microcontrollers, signal processors, and transmission devices are some other types of electronics. Smart power control is important for keeping batteries safe and making sure they last a long time. Sensor data is interpreted by microcontrollers and signal processors, AI models are run, and control signals are sent to motors. Communication parts, like Bluetooth or Wi-Fi units, let the prosthesis connect to outside devices so that it can be set up and inspected.
The artificial hardware is built around this combination of sensors, motors, and electronics, which lets it work like an extension of the user’s body.
Software Architecture: AI Models and Control Systems
AI-powered devices are built with software design that makes them work better, respond faster, and give users more control. Usually, the design is made up of several layers:
Control Systems are in charge of the prosthetic’s basic operations, such as turning AI model results into orders for the actuators. This method makes sure the movements are smooth and organised, so they look and feel like real limb actions.
· AI Models are at the heart of how the software is built. These models take in information from sensors to figure out what the user wants and then decide how to respond. Machine learning methods that have been taught on data from similar people and lab settings are what the models are built on.
· Software for the user interface lets the person change and customise the prosthetic’s settings to their liking. It lets people give input on how comfortable it is and how well it works, which can be used to train and improve the AI models even more.
· Middleware and APIs make it easier for hardware and different software components to talk to each other. They make sure that data from the sensors to the AI models and back to the controllers moves smoothly.
· The device stores, retrieves, and processes data in real time with the help of data management systems. This includes monitor reports, user choices, and details on how well the system has worked in the past.
This stacked software design makes it possible for control systems to be strong, scalable, and adaptable so they can meet the needs of different users.
Integration of Hardware and Software Components
Hardware and software must be fully integrated in AI-powered devices for the systems to work smoothly and provide a solution that is focused on the user. There are several important steps in the merging process:
· It makes sure that data from EMG sensors, brain sensors, and IMUs is sent to software systems correctly so that they can be processed. To make sure the data is correct and reliable, this needs to be precisely calibrated and aligned.
· Data synchronisation lines up the streams of data from different sources so that the AI models can understand them properly. This is very important for time and coordinating how your limbs move.
· There is Real-Time Processing features built in so that the software can quickly process sensor data and send out control messages. This is necessary for the device to act quickly when the user tells it to.
· Between the output of the motors and the input of the sensors, feedback loops are set up. This lets the system fix itself and adjust to outside conditions, which makes the device more useful and safe.
In testing and validation, the combined system is put through a lot of tests to make sure it works as planned in a variety of situations. This includes tests done in the lab and tests done by real people.
Design Considerations for Usability and Safety
When AI is used to run implants, designers have to think carefully about how safe and easy to use the devices are for users to make sure they meet their useful needs and are safe to use.
· The limb must be easy to wear for long periods of time; ergonomics is the most important thing to think about. This means making the device so that it fits tightly and snugly, and using materials that are light and gentle on the skin to keep it from getting irritated.
· User Interface Design needs to be simple and easy to understand so that people can handle and change their prosthetics without much trouble. As part of this, open software apps that users can directly work with are being made.
· Safety features are built in to keep accidents from happening during usage. This includes fail-safes that turn off the prosthesis if something goes wrong and warning systems that let the user know when something very bad happens.
· To meet the wants and tastes of a wide range of people, customisation and adaptability are important. The device should have a lot of different settings that can be changed, like how strong the grip is, how fast you walk, and more.
· Compliance with Regulatory Standards makes sure that all health and safety rules are followed by the prosthesis. This means going through the testing and licensing steps that medical device regulatory groups set out.
· People who use implants are given training and support to make sure they can use and take care of them properly. In addition to full training classes, this includes ongoing support services.
Developers can make sure that AI-powered devices are not only cutting edge technologically, but also useful and safe for everyday use by taking these things into account.
RESULT AND DISCUSSION
Analysis of the AI System’s Performance in Real-Time Control
The AI system’s performance in real-time control of prosthetics is a cornerstone for the enhanced functionality of these advanced devices. By integrating cutting-edge AI algorithms, the system can interpret sensor data almost instantaneously and translate it into precise, controlled movements. Our analysis of the system’s real-time performance involved measuring the accuracy and speed of response to user-initiated commands. The results indicate a significant improvement in the system’s ability to execute complex movements smoothly and without noticeable delay. The latency, previously a notable issue in older models, has been reduced to milliseconds, facilitating a near-natural response time. Additionally, the precision of movement execution, critical for tasks requiring fine motor skills, has reached an accuracy rate approaching 95 %. This high level of performance is achieved through the continuous learning capabilities of the AI, which adapts and optimizes its responses based on ongoing user interaction. The integration of deep learning frameworks has particularly enhanced the system’s ability to understand and predict user intentions with greater accuracy, thus significantly reducing errors and improving user satisfaction with the prosthetic’s performance.

The big performance gains of an AI-powered artificial system are shown in the table 2, showing how they were before and after a set of changes. The data shows improvements in a number of important factors that show how well the system works and how the users feel about it generally. Accuracy in moving the number of executions went up from 80 % to 95 %. This big improvement shows that the system can now accurately understand and carry out user orders, which is a basic feature that has a direct effect on how useful and reliable the prosthesis is. Response Time Reduction went from 50 % to 80 %, which means that the device responded faster to user inputs as shown in figure 2.
Figure 2. Before and After Optimization Comparison
For people who depend on the prosthetic for daily tasks, this improvement is very important because it makes using the device more natural and obvious, almost like using a real leg. Movement Getting Better From 60 % to 90 %, smoothness went up. For the user’s comfort and happiness, movement must be smooth. This makes sure that actions made with the prosthetic are not only accurate but also fluid, which lowers the mechanical feel and makes the motion of the limb more natural. The task-specific accuracy went up from 70 % to 92 %. This number is very important for jobs that need precise control and care, like typing or moving fragile things around. The change means that the prosthesis can better adapt to different jobs, making it more useful and flexible. User Perceived Responsiveness went up from 65 % to 88 %, which shows how well users think the device reacts to their orders. This measure of user happiness is very important because it has a direct effect on how much the user trusts and relies on the technology in their daily lives.
Effectiveness of Sensory Feedback in User Operations
The effectiveness of sensory feedback in our AI-powered prosthetic systems has profoundly transformed how users interact with their environment. Sensory feedback, especially tactile and proprioceptive, is critical for users to perform everyday tasks efficiently and safely. By embedding sensors that mimic the nerve endings of a biological limb, our prosthetics can relay information about touch, pressure, and temperature back to the user. This feedback loop not only increases the accuracy of tasks that require delicate handling, such as picking up glass objects, but also enhances the user’s confidence and overall satisfaction with the prosthetic. In our studies, tasks that previously had a high error rate saw a reduction in mistakes by over 30 % once sensory feedback was implemented. Users reported feeling more ‘connected’ to their prosthetic, noting that it felt more like a part of their body than a foreign tool. This integration has been particularly beneficial in complex environments where sensory input can be critical for navigation and interaction, as represent it in figure 3.

The table 3 shows a strong contrast between how well an AI-powered mechanical device works with and without sense feedback methods. The changes made to all factors after comments were taken into account show big gains in usefulness and user experience. Finishing the task the level of accuracy went from 55 % to 85 % with input, showing how important sense information is for making task performance more precise and reliable. This is very important for jobs that need to be done very carefully, since users count on comments to make sure they are doing things correctly. Handling Delicate Objects got a lot better, going from 50 % to 80 % improvement. This measure is very important for people who need to work with delicate or complicated items and need to be able to control their fine motor skills and handle them carefully. The sense feedback helps people figure out how much force they need to use, which lowers the risk of damage by a large amount. It went from 40 % to 75 % more realistic in terms of sensory details. This means that the artificial now gives people feelings that are more like those of a normal limb, which makes how they see and connect with their surroundings better. The number of tasks that users were confident in going up from 60 % to 90 %. This shows that physical input has a direct effect on users’ trust in the device’s skills, which lets them do more of a range of activities. The time it took to complete a task went down from 20 % to 50 %. This drop shows that tasks are being finished faster, which suggests that users are able to do things more quickly because the device gives them clear and accurate input.
User Adaptability and Learning Curve
User adaptability and the associated learning curve are critical factors in the success of new prosthetic technologies. Our research indicates that while initial adaptation to AI-powered prosthetics involves a learning period, users can achieve a high level of proficiency within a few weeks. This learning curve is expedited by the AI’s ability to adjust its behavior based on the user’s specific needs and preferences. Over time, users not only become more comfortable with the prosthetic but also learn to execute tasks more efficiently, with the prosthetic’s responses becoming increasingly intuitive. For example, in our study, the average time taken for a new user to perform complex tasks decreased by 50 % after one month of regular use. This improvement is largely due to the prosthetic’s machine learning algorithms, which continuously refine and customize the user interface and control strategies. As users train with their prosthetic, the system gathers data to further reduce the cognitive and physical effort required to operate the limb, effectively making the technology an extension of the user.

The table 4 gives a full picture of how people improved over four weeks while getting used to an AI-powered device. The improvements seen across a number of measures are significant, showing how well the flexible learning features built into the prosthesis design work. Basic Task Proficiency went from 40 % to 85 %, which is a huge jump. This big jump shows how, over time, people who use prosthetics get much better at doing everyday things with them. The fast progress is also due to the device’s simple design, which works well with the way people naturally move. From 25 % to 75 %, proficiency in Advanced Tasks went up, as shown in figure 4. This big step forward in doing difficult tasks shows that the prosthetic’s learning methods are able to change to the user’s needs and habits, letting them do more things as they get better at them. Cognitive Load went down from 30 % to 70 % less. This big drop means that people who use prosthetics will need less mental effort to use them as they get used to them. The prosthetic’s ability to guess and react to what the user wants is very important in this situation; it makes the device feel more like an extension of the user’s own body. The speed at which tasks were completed improved from 35 % to 80 %. The faster movement shows that the learning curve is levelling off, which means that users not only understand but also better use the prosthetic’s features. The level of comfort for users with prosthetics went up from 50 % to 90 %. This rise is a strong sign of the prosthetic’s practical design and the fact that it can be adjusted to fit each person. This makes the device more comfy over time.

Comparative Analysis with Traditional Prosthetic Devices
When as compared with traditional prosthetic gadgets, AI-powered prosthetics show superior overall performance across numerous dimensions. Traditional devices frequently provide simple functionality without the capacity for actual-time control or version to the person’s environment. Our comparative evaluation highlights that AI-better prosthetics not best outperform in phrases of operational efficiency but additionally substantially improve consumer pleasure and physical consolation. for instance, AI prosthetics are able to reducing bodily stress by using adapting movements to the consumer’s walking patterns or grip strength, which traditional prosthetics can’t replicate. Additionally, the precision of movement with AI prosthetics is substantially higher, that’s essential for tasks requiring quality motor manipulates. Our research display that consumer satisfaction scores for AI prosthetics average around 95 %, in comparison to 60 % for traditional fashions. the integration of AI allows a greater personalized and responsive revel in, making those advanced prosthetics superior for users searching for an improved exceptional of life.

The table 5 shows a comparison between standard prostheses and ones that use AI. It is clear that the AI-enhanced devices work better in a number of important ways. People who depend on artificial technology for daily tasks and quality of life need this improvement more than anything else. Task Execution Speed goes from 40 % for regular prosthetics to 85 % for AI-powered prosthetics, which is a big jump. This improvement shows that AI devices have more advanced methods and faster working power, which lets them respond to user orders more quickly and finish jobs faster. The number of correct movements has gone up from 50 % to 90 %. The prosthetic can move more like a real leg because AI technologies make sensing and motor control much more accurate. This is important for making the prosthetic work well and safely. The better experience people have with AI devices is shown by the fact that user satisfaction has gone up from 55 % to 95 %. Customisation and flexible learning in AI systems make it much easier for users to deal with prosthetics, making them more natural and adaptable to each person’s needs. Physical strain drops sharply from 70 % to 30 %, demonstrating that AI prosthetics are better at coordinating with the user’s natural movements, thereby lowering the effort and discomfort usually connected with prosthesis use. The ability to adapt to different tasks has gone up from 30 % to 80 %. AI-powered devices can change a lot of things in real time, which makes it easier and faster for users to do a lot of different things, a shown in figure 5.

CONCLUSION
The creation of prosthetics driven by AI is a big step forward in the field of rehabilitation technology. These devices give people who have lost limbs more movement and real-time brain control. It has been shown in this study that adding artificial intelligence to mechanical devices not only makes them more useful, but it also makes the user experience much better. Using advanced AI algorithms and machine learning methods, we’ve been able to make prosthetics that move very much like real limbs. This bridges the gap between mechanical devices and natural human functions. Putting AI to use in limbs has made huge steps forward in a number of important areas. First, movement execution accuracy has greatly improved, giving users a level of skill that is very close to that of a real limb. For example, this is very clear when doing things that need precise fine motor skills. Aside from that, these AI-driven devices now have much faster response times, which make it easier for the user to connect with the device. Cutting down on delay not only makes the prosthetic more useful for everyday tasks, but it also gives the user more faith in its dependability. Additionally, one of the most important improvements made possible by AI is the ability of prostheses to provide real-time sense input. With this feature, the device stops being just a tool and becomes an important part of the person’s body image, which makes their life much better overall. Sensory input, which can be touch, pressure, or even temperature, lets people connect with their surroundings in ways that were hard or impossible to do before. Another great thing about implants driven by AI is that they are very flexible. These devices can learn from how the user moves and always change to their specific needs. This personalised method not only shortens the time it takes to get used to the limb, but it also keeps improving its fit and usefulness over time. Because of this, the user’s mental load is greatly lessened, which makes it easier for them to use the device in their daily lives. Additionally, tests comparing AI-powered models to standard prosthetics have made it clear that the latter are clearly better. People who use these more modern implants are happier with them because they work better and are more comfortable to wear. It makes more sense to switch to smart prosthesis options because they reduce physical pain and make it easier to do more things.
