Claim 10:
11. A glucose sensor for calibrating one or more sensor parameters used for measuring a level of glucose in a body of a user, the glucose sensor comprising:
a working electrode;
physical sensor electronics configured to periodically measure electrode current signal (Isig) values for the working electrode and Vcntr values of counter voltage for the glucose sensor; and
a microcontroller configured to
generate Electrochemical Impedance Spectroscopy (EIS) parameter values for the working electrode based on an EIS procedure;
based on the Isig values, the EIS parameter values, the Vcntr values, and a plurality of sensor glucose (SG) predictive models, calculate a respective SG value for each of the SG predictive models;
apply a factory calibration factor to fuse the respective SG values to calculate a single, fused SG value;
perform error detection diagnostics on the single, fused SG value to determine whether a correctable error exists in the single, fused SG value;
in a case where the error detection diagnostics determine that a correctable error exists, correct the correctable error to generate a corrected, single, fused SG value; and
provide the corrected, single, fused SG value.
