Abstract: Various examples are directed to systems and methods of and using analyte sensors. An example analyte sensor system comprises an analyte sensor and a hardware device in communication with the analyte sensor. The hardware device may be configured to perform operations comprising applying a first bias voltage to the analyte sensor, the first bias voltage less than an operational bias voltage of the analyte sensor, measuring a first current at the analyte sensor when the first bias voltage is applied, and applying a second bias voltage to the analyte sensor. The operations may further comprise measuring a second current at the analyte sensor when the second bias voltage is applied, detecting a plateau bias voltage using the first current and the second current, determining that the plateau bias voltage is less than a plateau bias voltage threshold, and executing a responsive action at the analyte sensor.

Abstract: Aspects of the present disclosure provide a power activation module for powering one or more wearable electronic components. The power activation module includes a switch configured to provide a path for current flow between a battery associated with the power activation module, the one or more wearable electronic components, and a ground terminal. The power activation module also includes a sensor configured to detect whether a signal is applied to the sensor and, based on the detection, output a first digital output signal for controlling, at least in part, the switch to control the current flow from the battery to the one or more wearable electronic components. The power activation module also includes a lock pin configured to receive a lock signal, wherein when the lock signal is received, the switch is locked to allow current flow from the battery to the one or more wearable electronic components.
