WHAT IS PIEZOELECTRIC EFFECT ?

Page 3: Piezoelectric effect (in non-traditional machining)

HISTORY The first demonstration of the direct

piezoelectric effect was in 1880 by the brothers Pierre Curie and Jacques Curie.

The first practical application for piezoelectric devices was sonar during world war-I.

One significant example of the use of piezoelectric crystals was developed by Bell Telephone Laboratories.

APPLICATION IN NON-TRADITIONAL MACHINING Piezoelectric Effect use in USM to generate

ultrasonic vibration. Circuits

PROS AND CONS Have a high Stiffness value and produce a

high output with very little strain. Operation over long cables may affect

frequency response and introduce noise and distortion, the cables need to be protected.

Can be used only for dynamic pressure sensing as in case of static sensing the signals will decay away.
