Non-polarizable dry biomedical electrode
First Claim
1. A dry electrode system for the detection of biopotentials existing on the surface of the skin of a living body, comprising:
- a dry electrode having opposed sides, one of which is adapted to contact said skin, said dry electrode comprising a non-polarizable conductive substrate having opposed sides, and first and second adhesive layers applied to the opposite sides of said non-polarizable conductive substrate, said first adhesive layer being ionically conductive and adapted to adhere said dry electrode to said skin; and
a non-polarizable electrically conductive contact adhered to by said second adhesive layer and in conductive contact with said substrate via said second adhesive layer for conducting a biopotential from said dry electrode.

Abstract
A dry electrode for the detection of biopotentials existing on the surface of the skin of a living body, including a non-polarizable dry electrode pad having opposed adhesive surfaces, one of which is adapted to engage the skin of the living body and extend ionic charge conduction from the body to the surface of a non-polarizable electrode interface within the pad. An electrically conductive contact makes electrical and mechanical connection from the electrode pad to a wire or electronic amplifier by means of a second adhesive surface on the electrode pad. In a preferred embodiment, conductive adhesive layers are applied to opposed sides of a conductive foam pad to construct the dry electrode pad.
