20mm Buzzer COPPER PIEZO ELEMENT 20mm Sounder Sensor Trigger Drum Disc Vibration Knock Sensor Copper Piezo Element With Cables

A piezoelectric transducer converts mechanical force into electrical output. This made up of Quartz crystal which contains SiO2. Piezoelectric crystals electrically neutral. The atoms inside the crystals in an unsymmetrical manner but their electric charges balanced

When the force applied to stretch or bend it, an electric voltage generated. If there is no stress, no charges induced. When there is a stress, positive charges induced in one side and negative charges induced on the opposite side. Compression occurs in the crystal as the force applied.
