A New Wearable Ultrasound Muscle Activity Sensing System for Dexterous Prosthetic Control

In this paper we introduce a novel Wearable Ultrasound Radial Muscle Activity Detection System (WURMADS) and a demonstration of its ability to recognize forearm muscle activities of amputee subjects to control a dexterous prosthetic hand. The system consists of control electronics to capture and record the ultrasound echo signals in real-time and two wearable bands embedded with eight ultrasound transducers. Based on the principles of...
