Description

<p>Electromyogram (EMG) signals represent the electric potentials on the surfaces of muscles. These signals may be applied for controlling prosthetic replacements such as a prosthetic hand. This paper treats on application of EMG prosthetic hand for congenital defects. The experimental product of EMG prosthetic hand is developed for the subjects under 5 years old. The main problem of experimental product is a design issue of socket of amputee. The socket needs to support all weight of prosthetic hand and object of handling. Furthermore, EMG sensor electrodes are needed to be attached on the surface of amputee side firmly, in order to avoid noise. Therefore this paper proposes new socket design by using conductive polymer and flexible fabric. The experimental result shows that the prototype socket is applied for infant amputees and succeeded to grasping and releasing small object and holding big heavy object by using EMG prosthetic hand.</p>
