Development of a system for finding best electrode position for myoelectric hand control for derating of upper limb amputee.

The artificial hand controlled in myoelectric signal is referred to the myoelectric hand. The myoelectric hand controls a switching action of terminal device by changing the voltage of EMG signal generated by the contraction of the muscle remaining upper limb stump. Two signals are necessary to control of switching action. It takes a long time to determine the best point where EMG signal picked up. The aim of this study is the development of a system for finding best electrode position to control a myoelectric hand for derating of upper limb amputee. We developed an electrode position finding system by using "a band-type multi-electrode" and confirmed validity of this system.
