Comparison between force sensors to surface EMG electrodes used in hand prosthetics

Abstract

Design of modern prosthetic hand that have multiple degrees of freedom and able to move multiple fingers and wrist simulataneously, it has been important to use different sensor structures having advantegous in both size and energy usage. In this study, it is investigated whether piezoelectricity-based force sensors can be used instead of EMG sensors in prosthetic hand design or not. As a result of experimental studies, it is shown that using piezoelectricity-based force sensors is more affordable instead of using EMG sensors.
