1. A system for continuous glucose sensing, the system comprising:

  • an implantable continuous glucose sensor configured to generate sensor data associated with glucose concentration in a host; and

    sensor electronics configured to;

    apply a voltage to the implantable continuous glucose sensor at a first setting,switch the voltage applied to the implantable continuous glucose sensor to a second setting, wherein the first setting is different from the second setting,measure a signal response of the electrochemical glucose sensor responsive to a change in the voltage applied, wherein the signal response is associated with a sensitivity change of the implantable continuous glucose sensor,calibrate the sensor data, wherein the calibrating accounts for the sensitivity change, andgenerate at least one glucose concentration value based on the calibrated sensor data.
