Abstract: Techniques disclosed herein relate to glucose level measurement and/or management. In some embodiments, the techniques involve obtaining in vivo characteristics of a glucose sensor predicted using fabrication process measurement data associated with the glucose sensor, the in vivo characteristics including an in vivo sensitivity, an in vivo intercept, or a combination thereof; receiving sensor measurement data measured by the glucose sensor, the sensor measurement data including sensor current (Isig), counter voltage (Vcntr), electrochemical impedance spectroscopy (EIS) data, an age of the glucose sensor, or a combination thereof; and estimating a sensor glucose (SG) value using an SG model, wherein input parameters of the SG model include the in vivo characteristics of the glucose sensor and the sensor measurement data, and the SG value is an output of the SG model.

Abstract: A system for reducing sensor variability includes a sensor configured to generate real-time data relating to glucose sensitivity. The system causes performance of accessing the real-time data from the sensor relating to glucose sensitivity and inputting the real-time data into a machine learning model. The system also causes performance of estimating by the machine learning model an expected glucose sensitivity based on the real-time data and correcting the glucose sensitivity based on the expected glucose sensitivity.

Abstract: An example method for calibrating a glucose sensor includes determining, by one or more processors, a set of electrical parameters for the glucose sensor of a plurality of glucose sensors and determining, by the one or more processors, a cluster for the glucose sensor based on the set of electrical parameters. Each cluster of the plurality of clusters identifies respective configuration information. In this example, the method includes configuring, by the one or more processors, the glucose sensor to determine a glucose level of a patient based on configuration information identified by the determined cluster.
