Some accelerometers use MEMS capacitors etched on a chip to measure the magnitude and route of the acceleration vector. They're used to detect modifications in acceleration, in tilt sensors, or to detect free fall, as sensors triggering airbag deployment, and in many other functions. Some fingerprint sensors use capacitors. Additionally, a consumer can adjust the pitch of a theremin musical instrument by moving their hand since this modifications the effective capacitance between the person's ha...
