27 MM Piezo Ceramic Elements Sounder Sensor Trigger Drum Disc + Wire Copper Piezoelectric Buzzer Copper 27mm

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.
