Abstract: A method for monitoring an analyte within the body of a patient, an analyst sensor, and an analyte monitoring apparatus are presented here. In accordance with certain embodiments, the method for monitoring an analyte within the body of a patient includes implanting an analyte sensor at a sensor placement site in the patient. The analyte sensor includes a reference electrode, a counter electrode, a primary working electrode having a first structure, and an auxiliary working electrode having a second structure different from the first structure. The method includes communicating a primary signal from the primary working electrode and an auxiliary signal from the auxiliary working electrode to a processor. Further, the method includes monitoring the primary signal and the auxiliary signal with the processor to characterize a change in a physiological characteristic at the sensor placement site.
