<strong>Piezoelectric</strong> <strong>Materials</strong><br />

Direct <strong>Piezoelectric</strong> Effect<br />

• ‘Direct’ piezoelectric effect occurs when a piezoelectric<br />

material becomes electrically charged when subjected to a<br />

mechanical stress.<br />

• These devices can be used to detect strain, movement,<br />

force, pressure or vibration by developing appropriate<br />

electrical responses, as in the case of force and acoustic<br />

or ultrasonic sensors.<br />
