Abstract
Abstract 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.
