Electrode
First Claim
1. In a medical electrode of the type including an electrically conductive stud member and a first electrically conductive material for electrically coupling the electrode to skin the improvement comprising:
- a substrate including a second electrically conductive material substantially chemically inert with respect to said first electrically conductive material and electrically coupled to said stud member, and a layer of a third electrically conductive material ionically reactive with said first electrically conductive material when current is transmitted therebetween, said layer being disposed on said substrate physically spaced from said stud member and electrically interfacing with said first electrically conductive material so as to define an electrical path from said first electrically conductive material, through said layer to said second electrically conductive material and from said second electrically conductive material to said stud member.

Abstract
An improved medical electrode is particularly adapted for transmitting DC currents. The electrode includes (1) an electrically conductive substrate electrically connected to a stud member and chemically inert with respect to the electrically and ionically conductive material, such as a gel, coupling the electrode to the skin of the user, and (2) a predetermined amount of an electrically-conductive material, preferably silver, disposed on the substrate in spaced relationship to the stud member and interfacing with the electrically and ionically conductive material.
