1. A disposable, skin-contacting body electrode having a selfcontained electrolyte gel therein, comprising:

  • a relatively thin, flexible, non-conductive sheet material having an aperture therein and an adhesive layer thereon for contact with the skin of a subject, a cup-shaped member, including a cavity therein, disposed in the aperture so that the opening of the cavity is toward the skincontacting area and the rim of the cup contacts the skin surface, a securing member bonded to the base of the cup-shaped member and the non-adhesive-coated surface of the non-conductive sheet material holding the cup-shaped member in the aperture thereof, a male snap connector having an inner conductive disc disposed in the base of the cavity of the cup-shaped member interconnecting with an outer conductive disc disposed over the securing member having means thereon for connecting a lead wire thereto, a strippable sheet covering only the adhesive-coated surface of the non-conductive sheet material, an electrolyte gel-impregnated pad disposed in the cavity of the cup-shaped member in contact with the inner conductive disc and extending beyond the rim of the cup-shaped member into contact with the skin surface when the electrode is applied to the skin, and a cap member over the pad and cup-shaped member including an inwardly extending flange around the inner circumference of the cap member which grips the side walls of the cup-shaped member to form an integral, frictional seal therebetween.
