BIONIC AND HYBRID PROSTHETIC HAND EMBODIMENT

摘要

The present invention relates to an active hybrid prosthetic hand working with Electromyography (EMG) signals taken on the front arm, so as to provide a hybrid embodiment by using the shape memory alloy (SMA) and DC motors at the same time, characterized in comprising flexor tendon facilitating the closing movement of the fingers; extensor tendon which is located at the back part of fingers, not in alignment with the palm, and which helps said phalanges springs (4) for the extension movement of the fingers; flexor-actuator SMA which provides the hand to close and grasp and which is connected with the flexor tendon; extensor-actuator SMA which facilitates the returning movement of the fingers by making an extension movement following the grasping and which is connected with the extensor tendon.
