What Does Piezoelectric Accelerometer Mean?

A piezoelectric accelerometer is a device that uses mechanical vibrations to measure acceleration on a surface. The piezoelectric accelerometer converts mechanical energy and motion into electrical energy proportional to the applied acceleration.

Techopedia Explains Piezoelectric Accelerometer

The piezoelectric accelerometer’s operational principle measures and converts mechanical force into an electric signal.

Piezoelectric accelerometers work when mechanical force is exerted on the accelerometer. This force is applied directly on to the piezoelectric material, usually crystals, which modifies its internal alignment of negative and positive ions and results in accumulation of a charge on the opposite surface.

This charge is calculated as the voltage generated by the piezoelectric material or the accelerometer, when being exposed to stress or vibration. Piezoelectric accelerometers have various implementations and applications in industrial devices and applications that rely on the evaluation of mechanical force and vibrations for their operation.
