Abstract
Abstract Electrode such as a post-operative electrode including a combination of plastic foam with an adhesive layer, an electrical communication conductor member such as a wire or a thin foil member such as aluminum or silver, a thin polycarbonate member or members loaded with a conducting material such as carbon, a conductive medium, and a liner member. 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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
151 words
Electrode comprising: a. a layer of high-impedance carbon-loaded polycarbonate film material of a thickness of 0.1-5 mils; b. a metalized layer of low-impedance metallic foil material vapor desposited over said film material in a like geometrical configuration as said film material; c. a layer of plastic covering material with adhesive securing means disposed on a side of said foil material opposite said film material, said plastic covering material slightly larger than said film material and said foil material, and said securing means joining said film material, said foil material, and said plastic covering material together; d. a conductive medium layer disposed on a side of said film material opposite said foil material and substantially covering said film material; and, e. snap means for electrically connecting to said electrode in electrical and mechanical connection to said foil material whereby said electrode maintains maximum flexibility and minimum profile over skin of an individual.
