1. A sensor system, comprising:

  • a subcutaneous or implanted sensor, said sensor having a plurality of independent working electrodes, a counter electrode, and a reference electrode; and

    sensor electronics operably coupled to said sensor and including;

    electronic circuitry configured to selectively perform an electrochemical impedance spectroscopy (EIS) procedure for one or more of said plurality of independent working electrodes to generate impedance-related data for said one or more working electrodes;

    a programmable sequencer configured to provide a start stimulus and a stop stimulus for performing said EIS procedure; and

    a microcontroller interface configured to operably couple the sensor electronics to a microcontroller.
