We face various situations where we have to measure physical quantities like mechanical stress applied on metal and temperature levels in our daily life. For all these applications we need a device which could measure these unknown quantities in units and calibrations familiar to us.
There are different methods to classify the transducers that comprise but not restricted toward the function of the transducer, structure otherwise the occurrence of their working.
Piezoelectric transducers are a type of electroacoustic transducer that convert the electrical charges produced by some forms of solid materials into energy. The word "piezoelectric" literally means electricity caused by pressure.
