NOVELTY - A first electrode layer (16) is printed on a first conductive layer (14) with an ink having a base selected from the group consisting of acrylics, alkyds, alginate, latex, polyurethane, linseed oil, and hydrocarbon emulsions. A second electrode layer (18) is printed on electrolyte layer with an ink having a base selected from a group consisting of acrylics, alkyds, alginate, latex, polyurethane, linseed oil, and hydrocarbon emulsions. A second conductive layer (20) is printed on second electrode layer.    USE - Method of making thin, flexible printed battery (claimed) used in transdermal delivery systems for pharmaceuticals to provide additional driving force to facilitate diffusion of drug across skin. Can also be used in skin sensors, such a those used to monitor blood sugar levels or control insulin pumps, to power smart baggage tags an identifications, and to power certain novelty devices such as greeting cards.    ADVANTAGE - Makes relatively inexpensive, thin, flexible, disposable low energy density battery.    DETAILED DESCRIPTION - The first conductive layer is printed on a flexible substrate (12). The electrolyte layer printed on first electrode layer comprises electrolyte salts and a matrix material selected from a group consisting of aqueous acrylics, polyvinylidine fluoride (PVDF), PVDF copolymers, polyacrylonitrite (PAN) and PAN copolymers. The flexible backing sheet may be any permeable or impermeable substance and may be selected from the group consisting of paper, polyester, polycarbonate, polyamide, polyimide, polyetherketone, polyetheretherketone, polyethersulfone, polyphenolynesulfide, polyolefins, e.g., polyethylene and polypropylene, polystyrene, polyvinylidine chloride, and cellulose and its derivatives.
