Abstract
An apparatus and method (4,5,6,7,2) for capacitive measurement of electrophysiological signals (1) suppresses or reduces motion artifacts by providing a feedback mechanism. An average voltage between a capacitive sensor electrode (1) and the body (3) is controlled so as to reduce or minimize motion-induced signals.
