Abstract:
A single biomedical electrode having a first portion and a second portion on the single electrode to provide a differing electrochemical potential, wherein the single electrode has a combination of the first portion and the second portion selected from the group consisting of(a) at least two electrical conductors of differing compositions contacting one field of ionically conductive medium of conductive hydrogel or adhesive, wherein one of the differing compositions is carbon or an inorganic oxide and the other differing composition is a metal and wherein one electrical conductor is on the first portion and wherein one other electrical conductor is on the second portion,(b) at least two fields of ionically conductive media of differing compositions of hydrogel or adhesive wherein one field of ionically conductive medium is on first portion and wherein one other ionically conductive medium is on the second portion, and(c) at least two electrical conductors of differing compositions contacting at least two fields of ionically conductive media of differing compositions of hydrogel or adhesive wherein one electrical conductor is on the first portion and wherein one other electrical conductor is on the second portion; wherein one field of ionically conductive medium is on the first portion and wherein one other ionically conductive medium is on the second portion.
