Development of new flexible dry electrode for myoelectric sensor using conductive silicone

This paper reports the development of a new electromyography (EMG) sensor for the myoelectric prosthetic hand. The myoelectric prosthetic hand is controlled by EMG which is detected from the surface of human skin. Our study focuses on the dry type sensor with flexible adhesion material to fit to the skin surface instead of metal electrodes. The developed electrode consisted of silicone and conductive silicone blended with conductive carbon black. These electrodes were mounted on myoelectric prosthetic hands that were applied to perform the Pick and Place Tasks to test the total performance of the control system. The results showed that the developed material obtained a thinner sensor than the conventional ones, which enabled it to naturally trace to the subject’s forearm shape without burden on the skin.
