Abstract: The disclosed techniques include applying one or more voltage pulses to a working electrode of a sensor probe. The techniques may also involve measuring, using a current sensor, a set of one or more current responses corresponding to the applied one or more voltage pulses, wherein the set of one or more current responses form a quasi-Cottrell profile that approximates a portion of a Cottrell curve. The techniques may further involve comparing a characteristic of the quasi-Cottrell profile to sets of predetermined Cottrell profiles. The techniques may further involve calibrating the current sensor based on the comparison.

Abstract: Processes for fabricating physiological characteristic sensor devices are disclosed here. An embodiment of the fabrication process forms a circuit pattern on a base substrate, where the circuit pattern includes circuit layouts for multiple die locations. Component stacks are mounted to the circuit layouts. Each stack has features and components to provide processing and wireless communication functionality for obtained sensor data. An enclosure structure is formed overlying the base substrate to individually cover and enclose each of the component stacks. Sensor elements are fabricated on another surface of the substrate such that each sensor element has electrodes coupled to conductive plug elements formed through the substrate, and such that each sensor element corresponds to one die location. Next, the substrate is separated into physically discrete sensor device components.
