Highlights
- Piezoelectric transducers are active transducers as they are of self generating type.
- Tiny microphones and speakers are made up of piezoelectric transducers.
- In direct piezoelectric effect, the transducer generates voltage on application of force or pressure or strain. Microphone is an example.
- In inverse piezoelectric effect, transducers convert electrical energy to mechanical energy. Speakers are example of it.
