Patent ID: 7979117

Claim:
A flexible dermal patch having a top surface and a skin contacting bottom surface, the patch comprising: at least one negative electrode and at least one positive electrode for electrical coupling to the skin portion and/or skin appendage of a subject, wherein the at least one negative electrode and the at least one positive electrode are disposed substantially coplanar on the skin contacting bottom surface and a first electrode of the at least one negative electrode and the at least one positive electrode is disposed on a skin contacting side of the skin contacting bottom surface; an internal flexible power source electrically coupled to the at least one negative electrode and the at least one positive electrode, wherein the flexible power source powers the patch and is disposed in or on the patch; and at least one separator comprising a porous non-conductive material retaining a conductive fluid/composition therein, said at least one separator disposed on a second electrode of the at least one negative electrode and the at least one positive electrode, the at least one separator being for preventing contact between at least one of the at least one negative electrode and the at least one positive electrode and the skin portion, wherein the first electrode does not include a separator comprising a porous non-conductive material disposed thereon.
