1. A method of calibrating an instance of a sensing element capable of providing an electrical signal influenced by a physiological condition in a body of a user, the method comprising:
obtaining, by a first electronic device, fabrication process measurement data corresponding to measurements that were performed on a substrate having the instance of the sensing element fabricated thereon, wherein the first electronic device is configured with a calibration model or communicatively coupled to a second electronic device configured with the calibration model, the calibration model being associated with the sensing element;
determining calibration data associated with the instance of the sensing element for converting the electrical signal into a calibrated measurement parameter based on the fabrication process measurement data using the calibration model, wherein determining the calibration data comprises providing, by the first electronic device, the fabrication process measurement data as input to the calibration model; and
calibrating, by the first electronic device and using the calibration data, the instance of the sensing element, wherein the calibrating of the instance of the sensing element comprises storing the calibration data in a data storage element accessible to a sensing arrangement including the instance of the sensing element, and wherein the sensing arrangement uses the calibration data stored in the data storage element to convert the electrical signal into the calibrated measurement parameter.
