Applications of Piezoelectric effect

Last time I have discussed about the piezoelectricity. Let us discuss about the applications of piezoelectric effect.

(a) Electro-mechanical transducers.

Piezoelectric effect is used to convert electrical energy into mechanical energy and vice-versa, that is the piezoelectric substances are used as electro-mechanical transducers.

If an electric signal is applied to one end of a quartz rod, the variations in strain generated in the rod in consequence of the effect propagate down the rod, resulting in a mechanical wave, or an acoustic wave on reaching the other end of the rod.

(b) Highly stable oscillators: Continue reading “Applications of Piezoelectric effect”
