Icelandic prosthetic maker Ossur’s Rheo Knee, billed as the first knee with artificial intelligence, combines up to 15 sensors, a processor, software and a memory chip to analyze the motion of the prosthetic and learn how to move accordingly.

Bionics industry researchers estimate the next five years will bring major advances, including mind-controlled prosthetics in which sensors are attached directly to a patient’s brain. Already, companies and universities are developing bionic feet, new cochlear implants to restore hearing to deaf people, prosthetic arms with embedded chips to control elbow and wrist movement, and hand prosthetics with artificial intelligence to control grip.
