Abstract: Described is a surgical tool having a unique blade comprised of a blank made of electrically conductive material, a first insulative member, a plurality of electrically conductive members laminated to the first and insulative member and a second insulative coating. The blade acts as a capacitive device or as a resistive device depending upon the precise configuration of the second insulative coating.

Abstract: A low-cost, disposable electrode for body surface stimulating applications having a backing layer formed from a sheet of foamed plastic material which is generally divided into two halves by a transversely extending fold line. The first half has an opening extending through the thickness dimension thereof and on a surface of the second half is adhesively affixed a flexible, conductive sheet which is so positioned that when the backing layer is folded along the fold line, the flexible conductive sheet fits through the opening formed on the first half. Completing the assembly is a layer of conductive adhesive which is affixed to the undersurface of the foamed plastic layer so as to abut the surface of the flexible conductive sheet exposed through the opening and an electrical lead connected to the flexible conductive sheet.
