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

  • generating a glucose signal associated with a glucose concentration in a host using a continuous glucose sensor;

    measuring a sensitivity change of the continuous glucose sensor over a time period; and

    determining using electronic circuitry, a stability of the continuous glucose sensor based on the measured sensitivity change, wherein the continuous glucose sensor comprises an electrode, and wherein measuring the sensitivity change comprises switching, cycling or pulsing a voltage applied to the electrode and evaluating a response to the applied voltage.
