Electromyography Data Transmission via Galvanic Coupling Intra-body Communication Link

Abstract

Intra-body communication (IBC) is a novel research filed that will promote personalized medicine by allowing real time and in situ monitoring in daily life. In this work, the energy efficient galvanic coupling (GC) technology is used to send electromyography (EMG) data through intra-body links. Real EMG data are first acquired and recorded with needle electrodes inserted in the muscle of a person's forearm. Then, the data are transferred via GC intra-body communication employing a GC sound card-based testbed. The experiments are conducted by transferring EMG data in both ex-vivo and in-vivo tissue with different electrodes placements. Almost error free performance is achieved with a robust and reliable communication, a valuable result in medical applications.
