Abstract
An apparatus comprising: at least one electrode, having a first potential, arranged to sense a biosignal; a conductive shield provided over the at least one electrode where the conductive shield is configured to be driven to a second potential wherein the second potential is equivalent to the first potential plus a multiple of an inverted common mode voltage; and wherein the conductive shield is coupled to a drain to enable triboelectric charges to be dissipated.
