Piezoelectric sensors / elements are devices that utilize the piezoelectric effect and are basically devices that convert voltage into vibration and vibration into voltage. It is usually convenient to measure knock (knock sensor
) or vibration (vibration sensor).
Currently, it is also widely used in power generation projects. Step current generation.
