The document discusses the piezoelectric effect, which is the generation of an electric charge in certain solid materials in response to applied mechanical stress. Piezoelectric materials exhibit this effect, developing a separation of electric charges. Examples include quartz and Rochelle salt. Piezoelectric transducers use this effect to measure physical quantities like force, pressure, or strain. They have advantages like high frequency response, ruggedness, and not requiring external power, but their output is low and impedance is high. Applications include dynamic measurement and studying high speed phenomena.

2. PIEZOELECTRIC EFFECT

PIEZOELECTRIC EFFECT IS THE
PHENOMENON OF DEVELOPMENT OF
POTENTIAL DIFFERENCE DUE TO
SEPERATION OF CHARGES UPON THE
APPLICATION OF MECHANICAL
PRESSURE.

4. PIEZOELECTRIC TRANCDUCERS

SUCH TREANSDUCERS WHICH ARE BASED
ON THE APPLICATION OF PIEZOELECTRIC
EFFECT ARE CALLED PIEZOELECTRIC
