The effect, discovered by Pierre Curie in 1883, is exhibited by certain crystals, e.g., quartz and Rochelle salt, and ceramic materials. When a voltage is applied across certain surfaces of a solid that exhibits the piezoelectric effect, the solid undergoes a mechanical distortion.

Crystals which acquire a charge when compressed, twisted or distorted are said to be piezoelectric. This provides a convenient transducer effect between electrical and mechanical oscillations. Quartz demonstrates this property and is extremely stable.

What’s more, the piezoelectric effect works both ways: stress a piece of quartz and you get an electrical output from it that is proportional to the stress it undergoes. ... Your old record player had a cartridge that used the piezoelectric effect, the ultrasonic transducers in your ancient car alarm used it,

Piezoelectric crystal oscillators are used as frequency standards (for example, replacing balance wheels in watches), and for producing ultrasound. Crystalline quartz is a good example of a piezoelectric material.

Certain crystals such as quartz, Rochelle salt, and some compounds of lead, zirconate, and titanate possess an important electro-chemical property called the piezoelectric effect. Basically, this is a process which involves the transformation of mechanical energy into electrical energy, and vice versa.
