Abstract

A non-invasive chemical monitoring device that is placed on the surface of the skin collects and measures the concentration of various chemicals within the body by outward diffusion of the chemicals from the interior of the body, through the skin and into the device, is prepared with a molded polymeric collection medium (1), adhesive surface (3), and a skin to patch transfer link (2).
