applications

what is Piezoelectric crystal????Crystal like quartz, tourmaline, rochelle salt etc cut with their faces perpendicular to its optic axis is known as Piezoelectric crystal.

what is Piezoelectric Effect????When pressure and tension applied to one pair of piezo electric crystal, the opposite charges appear across its faces this effect is known as piezo electric effect.

what is inverse Piezoelectric Effect????If an alternating voltage applied to the pair of opposite sides of piezo electric crystal, crystal starts vibrating and also produce the ultrasonic sound its known as inverse Piezoelectric Effect.
