Microelectrochemical Systems for Drug-Delivery
Iontophoresis is the transport of a therapeutic compound through the skin by means of an electrical current. In iontophoretic applications, the skin resistance is highly variable (10 k Omega cm(2)-5 M Omega cm(2)), current levels are high (0.1-10 mA) and treatment durations are short (< 24 h). Small size batteries for portable applications (watches, calculators) are optimized for low current levels and a long operational life-time. Current battery technologies are not suited for iontophoresis applications, hence, new battery technologies are a prerequisite to fully exploit the therapeutic advantages of iontophoresis.
