Piezoelectric Sensor Description
Piezoelectric sensors use quartz crystals to convert electrical energy into sound. When a voltage is applied, the crystal expands and contracts, generating sound frequencies. These sensors also operate in reverse: pressure or sound waves distort the shape of the quartz crystal, producing electrical energy. This generated electrical energy can be stored and harnessed using batteries and capacitors.
