Abstract
A multi-functional, differing electrochemical potential biomedical electrode is disclosed. Several embodiments are described based on the difference in composition of multiple conductors, the difference in composition of fields of ionically conductive media, or both on a single insulative backing of a tab/pad style electrode. A galvanic circuit can be created from electrodes of the present invention, permitting self-restoration of defibrillation recovery of monitoring electrodes and the powering of iontophoretic delivery of pharmaceuticals, among other uses.
