Surface electromyographic (SEMG) signals can be monitored noninvasively by using electrodes on the skin surface. They are the summation of all motor unit action potentials (MUAP) within the pick-up area of the electrodes, so they provide information of the neuromuscular activities of the examined muscle. In addition, these signals have been widely applied to clinical diagnosis, sports medicine, ergonomics, rehabilitation medicine, neurophysiology and electrophysiology. Aimed at control system for pow...
