Abstract
A transcutaneous electrode is disclosed having a sheet electrode of an electrically-conductive material with an electrically conductive layer affixed to a major portion of the lower surface thereof. A pad of electrically-conductive gel is applied to the lower surface of the sheet electrode over the electrically-conductive layer. An electrical conductor having an unsheathed end portion is secured to the upper surface of the sheet electrode by an electrically-conductive adhesive. A high dielectric cover overlays the end out portion of the electrical conductor, and is secured to the sheet electrode by the conductive adhesive. A method for making the electrode is also disclosed.
