Abstract
A flexible elongate strip assembly comprising at least one strip having a length and a plurality of longitudinally spaced-apart electrode structures carried by the strip. Each electrode structure is formed with a layer of an insulating material having substantially planar spaced-apart parallel outer and inner surfaces. Each layer of an insulating material is provided with a layer of a conductive material adhered to the inner surface and an opening extending between the outer and inner surfaces to expose at least a portion of the layer of a conductive material on the outer surface. A plurality of spaced-apart generally parallel traces are carried by the strip and extend longitudinally along the length thereof. Conductive elements are provided for connecting the traces to the layers of a conductive material. The exposed portion of the layer of a conductive material serves as a conductive surface for the electrode structure.
