Abstract

A thin sheet of metal is first etched in accordance with similar patterns after exposure through masks, from both sides, to form parallel strips which, preferably, extend to integral connecting elements and may, also, include printed circuit connections or components; one of the sides of the strips, additionally, includes transverse cross connections to provide for mechanical attachment of the parallel strips, permitting application of the parallel strips to a substrate, for subsequent removal, so that the resulting electrode will be a plurality of closely spaced parallel strips applied, for example by an adhesive, on a substrate, integral with connecting portions for a printed circuit.
