Nonetheless, the million-dollar question is how does a piezoelectric transducer operate? Any device that uses this transducer can convert a physical quantity into an electric signal.
Many kinds of transducers exist, and a Piezoelectric transducer is one of them. Typically, what a transducer does is convert a mechanical signal into an electrical signal.
A transducer is any device that we can use to measure such quantities. About piezo drive circuit ，Often, we need to measure physical quantities such as temperature, sound pressure, and mechanical stress.
