Abstract
Analyte sensor for use in medical devices for measuring analyte data such as glucose data, including: a power source providing electrical power to the analyte sensor, an enclosure of the analyte sensor, a sensor circuit powered by the power source and including two electrodes, wherein the electrodes each have a first portion that lies inside the enclosure and a second portion that lies outside of the enclosure. At least one protection unit is electrically coupled to the first portion of each of the two electrodes located inside the enclosure, wherein the at least one protection unit is configured to short-circuit the two electrodes in case a voltage signal from the sensor circuit applied to the electrodes exceeds a predetermined voltage threshold. A method for operating an analyte sensor is also disclosed.
