A small diameter flexible electrode designed for subcutaneous in vivo amperometric monitoring of glucose is described. The electrode is designed to allow “one-point” in vivo calibration, i.e., to have zero output current at zero glucose concentration, even in the presence of other electroreactive...http://www.google.es/patents/US6881551?utm_source=gb-gplus-sharePatente US6881551 - Subcutaneous glucose electrode
