A non-enzymatic implantable blood glucose detector. The detector makes use of a non-reactive tin oxide semiconductor measurement electrode which is suitably energized by an electrical power source. Variations in current density at the measurement electrode are related to variations in glucose content...http://www.google.es/patents/US5469846?utm_source=gb-gplus-sharePatente US5469846 - Implantable non-enzymatic electrochemical glucose sensor
