Abstract

An electrode for selective attachment to at least one of a garment and a subject is provided. The electrode includes a conductive member defining a first side and a second side; a conductive composition disposed on the first side of the conductive member, wherein the conductive composition has a first adhesive strength; and a pressure sensitive adhesive disposed on the second side of the conductive member, wherein the pressure sensitive adhesive has a second adhesive strength that is greater than the adhesive strength of the conductive composition. The electrode is interposable between the garment and the subject such that the conductive composition is adhered to the subject and the pressure sensitive adhesive is adhered to the garment. In use, upon removal of the garment from the subject the electrode is removed only from the subject.
