The prototype of the 3 D.O.F myoelectric hand system for the upper limb amputee

This paper suggest a prototype of a 3 degree of freedom myoelectric hand system for the upper limb amputee. It is consists of the 3 main part, the myoelectric sensor, the myoelectric hand, and training system: the first is a surface electrode myoelectric sensor to extract the raw electromyogram signal from the residual muscle of the upper limb amputee. To implement 6 essential function of the hand, three sensors are attached to the residual muscle. The next is a 3 degree of freedom myoelectric hand itself which alternates the role of the hand of the upper limb amputee. The final is training system which help the upper limb amputee to be well adapted with repetitive rehabilitation. We prove the validity of the system with experiment.
