#$%^&*AU2016216576B220180426.pdf#####WU I 1U60 ABSTRACT A method of calculating a single, fused sensor glucose value based on respective glucose measurement signals of a plurality of redundant sensing electrodes, comprises: performing respective electrochemical impedance spectroscopy (EIS) procedures for each of the plurality of redundant sensing electrodes to obtain values of at least one impedance-based parameter for each said sensing electrode; measuring the electrode current (Isig) for each of the plurality of redundant sensing electrodes; independently calibrating each of the measured Isigs to obtain respective calibrated sensor glucose values; performing a bound check and a noise check on said measured Isig and said values of the at least one impedance-based parameter and assigning a bound-check reliability index and a noise-check reliability index to each said sensing electrode; performing signal-dip analysis based on one or more of said at least one impedance-based parameter and assigning a dip reliability index to each said sensing electrode; performing sensitivity-loss analysis based on one or more of said at least one impedance-based parameter and assigning a sensitivity-loss index to each said sensing electrode; for each of the plurality of electrodes, calculating a total reliability index based on said electrode's bound-check reliability index, noise-check reliability index, dip reliability index, and sensitivity-loss reliability index; for each of the plurality of electrodes, calculating a weight based on said electrode's total reliability index; and calculating said single, fused sensor glucose value based on the respective weights and calibrated sensor glucose values of each of the plurality of redundant sensing electrodes.
