Self-Current-Generating Skin-Applicable Patch Comprising Biodegradable Metal
Summary
USPTO published patent application US20260097198A1 for a self-current-generating skin-applicable patch comprising biodegradable metal. The patch includes first and second electrode layers and a support layer with ionic solution, enabling iontophoresis and micro-current effects without external power. Application 19112970 was filed September 20, 2023.
What changed
USPTO published a patent application for a self-current-generating skin-applicable patch with biodegradable metal components. The patch features electrode layers and a support layer with ionic solution designed to enable iontophoresis and micro-current effects through self-generated electricity without external battery power.
Medical device manufacturers developing transdermal drug delivery or skin treatment technologies should monitor this application for potential competitive implications. Patent prosecution may lead to granted claims that affect product development freedom in the iontophoresis and skin patch space.

Abstract
Proposed is a self-current-generating skin-applicable patch with a first area in contact with the skin and a second area adjacent to and spaced apart from it, where either area contains a biodegradable metal, decomposable and absorbable through skin contact or reaction with tissue moisture. The patch includes a first electrode layer directly contacts the skin as a thin sheet integrated with the first area and has at least one fluid-transferable penetration part, a second electrode layer of a material with a different standard reduction potential is positioned opposite a skin-contacting side, partially extending to connect electrically to the second area, and a support layer, a hydrophilic sheet of predetermined thickness, is positioned opposite the skin-contacting side, having an ionic solution supported. Thus, sufficient iontophoresis and other micro-current effects with active ingredients are achieved through self-generated micro-current, even without a battery-like external power source.
