Abstract: A surface electrode for long-term electrical communication with a skin surface of a patient, the surface electrode including: (a) a highly-conductive foil, for operatively connecting to a power source, for communication of an electrical signal between the highly-conductive foil and the skin surface of the patient, and (b) a securing arrangement for securing the highly-conductive foil to the skin surface, wherein the foil has a plurality of macroscopic air-permeable regions for fluid communication of air with the skin surface, and wherein the plurality of macroscopic air-permeable regions has a first surface area, the foil has a second surface area, and a ratio of the first surface area to the second surface area is at least 0.1.

Abstract: A surface electrode for long-term delivery of an electrical signal to a skin surface of a patient, the surface electrode including: (a) a flexible, at least partially-conductive surface layer for physically contacting the skin surface, and for delivering thereto the electrical signal, and (b) an electrically conductive layer, operatively connected to the partially-conductive surface layer, for transferring the electrical signal thereto, wherein the at least partially-conductive surface layer has a thickness of less than 0.5 mm, and preferably contains a conductive gel or artificial skin.
