Here is a robotic prosthetic knee that uses artificial “muscle” powered by motors and sensors to allow above-knee amputees to walk naturally. The Bio Leg uses force, angle, and acceleration sensors to detect posture, movement and environmental changes. It relies on AI algorithms to adjust support dynamically. These prosthetic legs can handle 10k steps without user fatigue. The below video shows what makes this prosthesis special:
Bio Leg can recognize user intent to allow for natural transition from a chair to standing. It has an aluminum, titanium, and carbon construction. You can find out more here.
