Service-detectable analyte sensors and methods of using and making same
First Claim
Patent Images
1. A method, comprising:
- inserting at least a portion of an analyte sensor beneath the skin of a patient, wherein the analyte sensor comprises an indicator element that provides a sensor service history;
attaching an analyte sensor control unit to the skin of the patient to couplea plurality of conductive contacts disposed on the analyte sensor control unit to a plurality of contacts of the analyte sensor;
applying an initializing potential to the indicator element;
detecting a current generated by the indicator element; and
comparing the detected current to a control current to determine a sensor service history of the analyte sensor to identify the sensor as a previously used sensor or a previously unused sensor.
