590264 Disclosed is an electrode for a system for sensing electrophysiological signals. The electrode includes a carrier and a conductive element (54) mounted on the carrier. A shielding element (58) is carried by the carrier and maintained by the carrier in fixed, spaced relationship relative to the conductive element (54), out of plane of a surface of the conductive element (54) which picks up the electrophysiological signals. The electrode is a passive device free of any electronic components.
