Abstract

It is reported the design of electrodes which was standardized and positioned based on the anatomy study and motor units, identified by the nerve branches of an amputated leg (above the knee)[1], obtaining the myoelectric signals of maximum amplitude of 20 μV [2]. The initial identification of the optimal position of the electrode was characterized with myoelectrography in order to determine the movements that the patient makes consciously. The myoelectrical signal was accomplish by taking into account electrochemical schema of the the cellular membrane [3] based on the fields and frequencies, recognized by the circuit structural materials that provide sufficient resistivity to the spurious frequencies [4], isolating each motor unit [5]. The results show that it is possible to have a cleaned signal which describes the movement that the patient desires consciously and the application in a prosthesis.
