Abstract
A wearable device comprises an exteriorly positioned first electrode and a reporting capacitor. The first electrode forms a first side of the reporting capacitor, and a second side of the reporting capacitor is formed by skin of a user when the wearable device is worn. An oscillator is configured to output a signal to drive the first electrode at a first frequency. The oscillator is configured such that changes in capacitance at the reporting capacitor adjust the signal output by the oscillator from the first frequency to a second frequency. A frequency-to-voltage converter is configured to generate a voltage representation of the second frequency. A controller determines a change between the first frequency and the second frequency based on the voltage representation and indicates an amount of movement of skin of the user relative to the first electrode based on the determined frequency change.
