A piezoelectric sensor/element is a device that uses the piezoelectric effect, it is basically a device which converts voltage to vibration and vibration to voltage.
It normally comes in handy to measure knock (knock sensor) or vibration (vibration sensor). Now a days it is also used extensively in power generation projects e.g. Foot Step Power Generation.
