How does the Piezoelectric Effect Work for Motion? Piezo Mechanisms for Motion Control

POSTED 06/07/2019

“Piezo” is related to the Greek word for pressure. The “direct piezo effect” (pressure creates an electrical charge in certain crystals) and was discovered in the late 19th century by the Curie brothers. The direct piezo effect is used in sensor applications and for energy recovery. The “inverse piezo effect” (an applied voltage creates a change in shape in certain materials) is important for motion, positioning, sound and ultrasound transducers generation.
