Prosthetic arms have come a long way from the wooden and metal devices of the past. Today, some of the most advanced prosthetic arms use artificial intelligence (AI) and machine learning to mimic the natural movements and sensations of the human arm. These smart prosthetics can interpret the electrical signals from the wearer’s brain and use them to control the arm’s elbow, wrist, and fingers. They can also provide feedback to the wearer on their grip strength and the texture of the objects they touch.
How AI and machine learning work in prosthetic arms
AI and machine learning are technologies that enable computers to learn from data and improve their performance over time. In prosthetic arms, these technologies are used to analyze the electrical signals from the muscles and nerves of the residual limb, and translate them into commands for the prosthetic arm. The more the wearer uses the arm, the more the AI and machine learning algorithms can adapt and fine-tune the arm’s movements and responses.
One of the companies that is developing AI-powered prosthetic arms is Atom Limbs, based in California. Atom Limbs uses advanced sensors and machine learning to create a prosthetic arm that has a full range of human motion in the elbow, wrist, and individual fingers. The arm also provides haptic feedback to the wearer on their grip strength, using a system of air bladders and pressure sensors. The arm is non-invasive, meaning it does not require any surgery or implants to function. It connects to the wearer’s residual limb with bands of sensors and a cup that fits over the top.
The benefits and challenges of AI-powered prosthetic arms
AI-powered prosthetic arms offer many benefits to the amputees who use them. They can improve the functionality and quality of life of the wearers, by allowing them to perform everyday tasks more easily and naturally. They can also enhance the psychological and emotional well-being of the wearers, by restoring a sense of agency and identity. Some wearers have described using AI-powered prosthetic arms as a “mind-bending” and “magical” experience.
However, there are also some challenges and limitations to AI-powered prosthetic arms. One of the main challenges is the cost, which can be prohibitive for many amputees. The average price of a bionic arm can range from $20,000 to $100,000, depending on the features and customization. Another challenge is the availability and accessibility of the technology, which may not be widely distributed or supported in some regions or countries. A third challenge is the reliability and safety of the technology, which may be affected by factors such as battery life, software glitches, or external interference.
The future of AI-powered prosthetic arms
Despite the challenges, AI-powered prosthetic arms are expected to become more advanced and widespread in the future, as the technology improves and the demand increases. Some of the possible developments include:
- More intuitive and natural control systems, such as brain-computer interfaces, that can directly communicate with the prosthetic arm without the need for sensors or electrodes.
- More realistic and personalized appearance and design, such as 3D-printed skins, tattoos, or jewelry, that can match the wearer’s preferences and style. [5]
- More sensory and interactive capabilities, such as temperature, pain, or vibration sensors, that can provide more feedback and information to the wearer and the environment. [6]
AI-powered prosthetic arms are transforming the lives of amputees and the field of prosthetics. By using AI and machine learning, these smart prosthetics can offer more realistic and accurate movement and sensation, and more personalization and customization. They can also open new possibilities and opportunities for the wearers, who can regain some of the functions and feelings of their lost limbs.
