A Wireless and Digital Electrode Bus Topology for Biopotential Measurement

Abstract:
The conventional biopotential measurement configuration utilises long lead wires which connect measuring electrodes to signal conditioning circuitry. The majority of bioelectric signals that are measured from the human body have a tiny signal amplitude (5µV-5mV range) and thus any interference that is induced on the lead wires can have a detrimental effect on the original signal. In this paper, we present an alternative configuration, in which digitisation occurs on the electrode, potentially providing enhanced signal measurement as well as significant benefits in terms of the simplification of the physical interconnections between electrodes. Multiple electrodes are combined to form a digital electrode bus. This proposed topology represents the next stage in the evolution of bioelectric measurement as, due to the decrease in cost and size of integrated circuits, more of the bioinstrumentation circuitry is shifted away from a base measurement station and into the electrode itself.
