Abstract
A medical electrode for attachment to the skin of a patient has a cup member forming a cavity for containing an electroylyte. The cup member has a base portion which is movable inwardly of the cup member so as to contract the interior volume of the cavity and in so doing displace the electrolyte outwardly of the cup member for contact to the skin of a patient. In a modification, the configuration of the base of the cup member allows an electrode conductor to be supported out of contact with the electrolyte until the base portion is moved to displace electrolyte outwardly of the cup member.
