Piezoelectric Accelerometer: This device relies on the natural structures of piezoelectric crystals, which react to forces exerted on the phone by generating an electrical charge, which subsequently creates a voltage. An accelerometer is an electromechanical device used to measure acceleration forces. Several devices, part of the quantified self movement, use accelerometers.

The motion sensors in accelerometers can even be used to detect earthquakes, and may by used in medical devices such as bionic limbs and other artificial body parts.
