Abstract

An electrical device of the type having a conductive layer or film on a non-conductive base, characterized by an elongate non-conductive base, an electrically conductive track having a plurality of turns on the surface of the base, a non-conductive helical path around the base that separates the turns of the track from each other and that extends in the base of the base in less than 12.7 microns below the surface of the base, and a metal electrode in each end of said base, in electrical contact with said electrically conductive track.
