1. A system comprising:
one or more processors; and
memory storing instructions which, when executed by the one or more processors, cause performance of:
obtaining a measurement parameter representing an electrical response of a first instance of a sensing element to a physiological condition of a person;
converting the measurement parameter into a calibrated measurement parameter using calibration data specific to the first instance of the sensing element, wherein the calibration data is based on a fabrication process measurement performed with respect to a location of the first instance of the sensing element on a substrate;
determining a measurement value using the calibrated measurement parameter as input to a performance model, wherein the performance model is derived from historical calibrated measurement parameters and corresponding reference values, and wherein the historical calibrated measurement parameters are from other instances of the sensing element; and
sending a command to a medical device based on the measurement value, the command configured to cause the medical device to deliver a dose of medication influencing the physiological condition of the person.
