Forces from the sensing vane are transferred via the torque tubes to the
piezoelectric crystal sensors, which are placed in the wall of the flowmeter out of the flow stream.
Conventional ultrasound scanners use
piezoelectric crystals to create images of the inside of the body and send them to a computer to create sonograms.
It is noteworthy to mention at this stage that no previous investigations have been presented deriving explicit expressions for the deformed field components, or their angular variations near the tip of a crack, within a stack of nonuniformly loaded parallel cracks, even in hexagonal
piezoelectric crystals or purely isotropic elastic, nor even when the loads are uniform.
Piezoelectric crystals transform pressure or motion into electricity when they are compressed or vibrated; phonograph needles are one common example.
The equipment falls under Chapter 85 of the GST Rate Schedule for Goods and include diodes, transistors and similar semiconductor devices, photosensitive semiconductor devices including photo voltaic cells, light emitting diodes ( LED) and mounted
piezoelectric crystals.
Piezoelectricity is a well-studied electromechanical coupling effect in which the mechanical strain leads to electric polarization in
piezoelectric crystals, or vice versa.
Ultrasound images are generated by emission of high frequency sound waves from
piezoelectric crystals within the ultrasound probe.

piezoelectric crystals," in Proceedings of the IEEE International Ultrasonics Symposium (IUS '09), pp.
The brush also has a ceramic covering to maximise heat retention and
piezoelectric crystals which release ions to protect the hair and scalp.
McAlpine and his colleagues at Princeton have developed a way of converting everyday body movements into electricity using a flexible electricity-producing sheet of rubber imprinted with
piezoelectric crystals that can be implanted in the body.
Piezoelectric crystals make formidable transducers--a key component of medical, commercial, and industrial probes.
