METHOD OF SENSOR DIAGNOSTICS BASED ON APPLICATION OF ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY

A method provides for calibrating a sensor, the method comprises performing an electrochemical impedance spectroscopy (EIS) procedure for a working electrode of a sensor to obtain values of at least one impedance-based parameter for said working electrode; performing a bound check on said values of...

Zusammenfassung:A method provides for calibrating a sensor, the method comprises performing an electrochemical impedance spectroscopy (EIS) procedure for a working electrode of a sensor to obtain values of at least one impedance-based parameter for said working electrode; performing a bound check on said values of the at least one impedance-based parameter to determine whether said at least one impedance-based parameter is in-bounds and, based on said bound check, calculating a reliability-index value for said working electrode; and determining, based on the value of said reliability index, whether calibration should be performed, or whether calibration should be delayed until a later time.
