Abstract:
1. A method of enhancing conductivity of an electrical signal through a subject's skin using a microneedle electrode comprising: applying a microneedle electrode to the subject's skin by placing microneedles of the microneedle electrode in direct contact with the subject's skin; inserting the microneedles of the microneedle electrode into the skin such that the microneedles pierce stratum corneum of the skin up to dermis of the skin; and allowing an electrical signal to pass through the microneedle electrode where impedance of the microneedle electrode is less than 10 ohms, wherein the microneedle electrode comprises a conductive metal substrate having microneedles extending therefrom which is formed by etching or cutting a microneedle pattern into a sheet of conductive metal and bending the microneedles to a desired angle.
