An electrolyte gel matrix, which may be a conductive adhesive such as a urethane hydrogel, is located in a cavity formed in a non-conductive tray. The matrix is adapted to engage the skin of a patient and transmit signals between the skin and an electrode conductor supported by the base of the tray for exchanging signals with peripheral equipment. A stiffening platform adhered to the tray extends across the cavity portion aligned with the conductor to minimize motion artifacts associated with the use of the electrode. The electrode is removably attachable to the skin by an adhesive layer on the lower surface of the tray and by a preferably more aggressive adhesive layer on the lower surface of the platform.

A medical electrode comprising: electrically insulating means forming a tray having a cavity, said tray forming means comprising a cover member forming the base of said tray, and a frame connected to said cover member and forming a sidewall around said cavity; conductor means supported by said cover member having one portion located within one portion of said tray and another portion projecting outwardly of said cover member for transmitting signals between the skin of a patient and peripheral equipment, said conductor means extending only into said one portion of said tray and not into the remainder of said tray; an electrolyte gel matrix filling said cavity and having one portion engaging and covering said one portion of said conductor; electrically insulating platform means connected to said frame and spanning across a first part of said gel matrix including said one portion of said electrolyte gel matrix covering said conductor means for providing a barrier that covers and thereby shields said one portion of said gel matrix from either chemical or physical interaction with the skin of a patient to which the electrode may be applied, said first part of said gel matrix comprising less than the entire said matrix, and said gel matrix having a second part exposed by said tray and said platform means for engagement with the skin of a patient; and adhesive means for adhering said platform means and said frame to the skin of a patient with said second part of said electrolyte gel matrix engaging the skin.
