Abstract
A DC biopotential sensing electrode assembly is provided for an apparatus for sensing DC biopotentials present at the skin of a subject. An electroconductive medium for transmitting ions from the skin which has a chloride ion content within a range of from 6-15 grams per hundred grams of such medium is formulated for use with the electrode. To reduce the corrosive effect of this electroconductive medium, each electrode includes only one metallic component, and to provide an electrode with a low AC impedance, this metal is uniformly coated upon nonmetallic sensor and terminal bodies with a coating thickness within a range of from 0.5 to 1.5 mil. To insure a complete electrical path through both the sensor and the terminal bodies, the nonmetallic portions are formed of conductive plastic.
