Some accelerometers use MEMS capacitors etched on a chip to measure the magnitude and path of the acceleration vector. They're used to detect adjustments in acceleration, in tilt sensors, or to detect free fall, as sensors triggering airbag deployment, and in lots of different purposes. Some fingerprint sensors use capacitors. Moreover, a user can modify the pitch of a theremin musical instrument by shifting their hand since this modifications the effective capacitance between the person's hand ...
