Abstract
A wearable device is provided herein and includes an electrochemical sensor with a working electrode, a reference electrode, and a reagent that selectively reacts with an analyte. In accordance with one embodiment, a process is provided herein and includes applying an electric potential waveform pattern between the working electrode and the reference electrode, the pattern comprising a combination of a constant voltage and at least one voltage waveform including one or more of a triangle waveform, a pulse-step waveform, and a sine waveform, determining a current at the working electrode, the current resulting from the application of the electric potential waveform pattern, determining that the current is less than a threshold level of measured current, and in response, the wearable device stopping the application of the electric potential waveform pattern.
