Crystal Structure Analysis for Chemists and Biologists
A piezoelectric crystal contains moveable ions that, in changing position, cause a
change in the shape of the crystal. As pressure is applied to a piezoelectric
crystal, the crystal changes shape slightly by the movement of ions. Some of the ...

Principles and Practice of Ultrasonography
An example of natural piezoelectric crystal is quartz crystal. Ultrasound
application use a man made piezoelectric element such as ceramic crystal
component piezoelectric having mixture of lead zircoate, titanate (PZT) and
epoxy.

Christensen's Physics of Diagnostic Radiology
Heating a piezoelectric crystal above the Curie temperature reduces it to a
useless piece of ceramic, so obviously transducers should never be autoclaved.
The approximate Curie temperatures for several crystals are as follows:
Resonant ...

Multilayer Integrated Film Bulk Acoustic Resonators
According to the Sauerbrey's study of the mass sensibility of piezoelectric crystal,
the relation between the fundamental resonance frequency and the additional
mass on the piezoelectric crystal surface is f D 2.t/12f2m=A (9.1) where f is the ...

Piezoelectric Sensorics: Mechanical, ...
Closely related is the converse (reciprocal, inverse) effect, whereby a
piezoelectric crystal becomes strained if an external electric field is applied. Both
effects are the manifestation of the same fundamental property of the non-centric
crystal.

INDUSTRIAL ELECTRONICS AND CONTROL
Polarity of the potential on a piezoelectric crystal changes on changing the
direction of the mechanical pressure applied. The inverse of the piezoelectric
effect is called the converse piezoelectric effect. It is the potential difference
applied ...

Basic Electronics Engineering & Devices
In crystal oscillators, piezoelectric crystal are employed in place of RL or RC
circuit. The frequency of crystal oscillators remains more or perfectly constant
even if temperature changes. 15.6. CRYSTAL OSCILLATOR The crystal is
usually made ...

Medical Physics: Imaging
Electrode Conversely, if a voltage is applied across an unstressed piezoelectric
crystal, the centres of symmetry move, hence deforming the crystal. An applied
alternating voltage thus gives rise to mechanical vibrations in the crystal, or a ...
