1A1-K03 Myoelectric Prosthetic Hand with Exteriority and Functionality(Robot Hand Mechanism and Grasping Strategy(1))

In Japan, the penetration of electric prosthetic hand is low, that is around 1 %. The authors have developed a novel myoelectric prosthetic hand based on a survey on demand for prosthetic hands. The rounded appearance of our prosthetic hand is greatly inspired by female human hands. Our prosthetic hand is lightweight (under 300[g] yet achieves high grasping force (over 20[N]), and all parts are mounted in hand. Each finger has 1 degree of freedom for flexion/extension, and the thumb has 2 degrees of freedom for opposition and flexion/extension.
