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.
