A Novel Water Proof Prosthetic Hand Based on Conductive Silicon sEMG Sensors

Although current prosthetic hands can provide some hand functions for the amputees, they are impossible to be used in the water. During the amputees' daily lives, it is inevitable for them to use hands in the water environment, such as washing, swimming. In order to improve the quality of amputees' lives, it is very necessary to develop a water proof prosthetic hand. We develope conductive silicon surface electromyography (sEMG) sensors to acquire sEMG signals in the water environment. For sEMG signals collected by flexible water proof electrodes in the water, we develope sEMG signals recognition method. The experimental results show that we can control the prosthetic hand to complete four gestures based on the sENIG signals, and the accuracy is 93.89%. Therefore, it can be concluded that the sEMG signals recognition method and the prosthetic hand control system are feasible.
