Cosmetic or medical patches integrated with flexible printed battery. The battery enables the iontophoresis process. Iontophoresis is defined as the introduction, by means of direct electrical current, of ions of soluble salts into the tissues of the body for therapeutic purposes (Singh and Maibach, 1994). It is a technique to enhance the transport of drug ions across tissue barriers, such as the skin.
