The System Hand consists of three parts the hand chassis with hand mechanism, the shaped inner hand, and the cosmetic glove providing both functionality and a natural appearance. The hand mechanism is responsible for the gripping function. The System Hands voluntary opening and voluntary closing belong to the cable-activated prostheses or "active prehensile arms". They are controlled with a harness control system. The system inner hand encloses the hand mechanism and provides the shape of the cosmetic hand. The cosmetic hand is selected according to the size of the inner hand and is available in 18 colors.
