摘要： A method of operating an electrochemical analyte sensor having one or more electrodes may comprise applying a time-varying input signal to at least one of the one or more electrodes, monitoring a time-varying output signal produced by the sensor in response to application of the time-varying input signal, determining a complex impedance of the sensor based on the time-varying input and output signals, and determining from the complex impedance information relating to operation of the sensor.
