Abstract: The use of electrically powered hands is impeded by their control interfaces. EMG (electromyogram) based prosthetic control is very promising but its deployment is limited by problems with surface recording of EMG. EMG recorded from implanted electrodes seems to be good alternative. In this paper, we describe a system for artificial hand control based on implanted EMG. The system includes a data transfer link based on the IEEE 802.15.4 network, a power transfer scheme built around a pair of coupled inductors driven by a class E amplifier. The entire system can run off a mobile phone battery for around 4 hours. We describe the acquisition and classification of EMG into different groups and the effect of noise in the radio channel on the classification.

Keywords: prosthesis control; EMG classification; implanted EMG; artificial hand control; myoelectric control; myoneural interface implant; electromyograms; implanted electrodes; mobile phones; cell phones; phone batteries; artificial hands.
