ABSTRACT:
A flexible carrier sheet has an adhesive releasing outer surface and a heat-sealable inner surface, and one or more retaining pads are die-cut from a sheet or strip of breathable foam material attached to the outer surface by pressure-sensitive adhesive. Each retaining pad covers a hole cut within the carrier sheet and supports an electrical contact assembly which projects through the hole to confine an electrical conducting gel. A flexible bottom cover sheet has an air-impervious outer surface and a heat-sealable inner surface, and the edge or border portions of the carrier sheet and bottom cover sheet are heat-sealed together to form an air-tight chamber for the gel. The carrier sheet and bottom cover sheet may also be heat-sealed together in an area extending between adjacent electrodes, and the heat-sealed area may be provided with a line of weakening to provide for convenient separation of single electrode assemblies.
