The foil member and polycarbonate member are thin providing for flexibility and low profile, and are substantially of like identical surface area. The conductive member can be either karaya, electrode gel, ionic polymer, or other like medium. The electrode is very flexible and very conforming to the surface of the skin of the individual user. | |
