Description
Summary:An optimized circuit for processing of EMG signals has been designed and presented in this paper. This circuit acquires EMG signals from surface of the skin using bipolar electrodes and enables the amputee to control the prosthetic hand in an efficient manner. EMG can be defined as the electrical potential produced due to the contraction of muscle. It can be picked from the residual portion of muscles of an amputee. EMG signal requires the processes of amplification, band limiting and rectification, before it can be fed to an analog to digital converter (ADC) and subsequently to motors driving the prosthetic device.
