Smart Artificial Limbs

Traditional leg prosthetics enable amputees to maintain mobility and lead more active lives. Leg prosthetics most commonly fit amputees’ residual limbs via a socket that encloses the limb like a wooden clog. Because the socket exerts pressure on the limb’s soft tissue, pain and chafing, sores and blisters, and...
