It is Piezo Electric Effect and you should try an internet search before submitting such misspelt questions.
Piezoelectric effect is the generation of electrical potential across the faces of a quartz crystal when subjected to stress and vice versa. Other substances also exhibit this effect. Used in production of ultrasonic transducers, lighters etc.
