TRANSDERMAL GLUCOSE DETECTING BIO-SENSOR USING REVERSE IONTOPHORESIS

摘要

PURPOSE: A transdermal glucose detecting bio-sensor using reverse iontophoresis is provided, thereby rapidly and easily detecting the glucose concentration in blood without pain. CONSTITUTION: A transdermal glucose detecting bio-sensor using reverse iontophoresis comprises (1) a pair of extraction electrodes for extracting biochemical materials; (2) hydrogel compatible with the skin tissue of the human body and containing enzymes converting biochemical materials to the materials producing electric signals; (3) a 3-phase electrode system converting the quantity of the extracted materials or converted materials of the extracted materials to the quantity of electricity, wherein in case of using these electrodes together with methacrylate family as hydrogel and glucose oxidase, the transdermal glucose detecting bio-sensor has the electric current difference of 0 to 200 nA after 40 seconds of analysis when 1.0mAxmin of electric current is passed through the human body, glucose is extracted and the glucose concentration is analyzed.
