ABSTRACT:
A sheet of resilient foam material is releasably attached by adhesive to an air impervious carrier sheet and is die cut to form on the carrier sheet an annular pad surrounding a center section. The center section and its corresponding adhesive are removed to define a center opening which receives a molded flexible hub member. The hub member has a top wall which connects with an annular U-shaped channel portion forming an annular hinge and cooperating to define a chamber closed by the carrier sheet. An electrical contact assembly extends from the chamber through the top wall portion of the hub member, and a resilient foam pad or patch containing an electrically conductive gel is confined and sealed within the chamber. The hub member also includes a flexible flange portion which projects outwardly from the U-shaped channel or hinge portion and is permanently bonded or attached to the top surface of the annular pad of resilient foam material.
