Energy efficient galvanic coupling (GC) technology is used in this work to send electromyography (EMG) data through intra-body communication 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 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.
