This project presents the development of prosthetic hand using surface Electromyogram (SEMG). The main aim of this project is to create low cost prosthetic hand which can be controlled by SEMG signal, extracted using analog circuits. The proposed circuit is designed for capturing surface EMG signal from surface of the human hand. The analysis of the output signal of the developed circuit is described in this report. The final analysis of the output from muscle sensor is passed to Arduino board to control the servo motors of prosthetic hand.
