Abstract (en)
[origin: WO9611631A1] A DC biopotential sensing electrode assembly (106) is provided for an apparatus (10) for sensing DC biopotentials present at the skin of a subject. The electrodes (106) include an electroconductive medium (158) for transmitting ions from the skin which has a chloride content within a range of from 6-15 grams chloride ion per hundred grams of such medium. To reduce the corrosive effect of this electroconductive medium, each electrode includes only one metallic component (122, 144), and to provide an electrode with a low AC impedance, this metal is uniformly coated upon nonmetallic sensor (120) and terminal (142) bodies with a coating thickness within a range of from 0.5 to 1.5 mil. To pressure a complete electrical path through both the sensor and the terminal bodies, the nonmetallic portions (120, 142) are formed of conductive plastic.
