Related to piezoelectric effect: Piezoelectric transducer

pi·e·zo·e·lec·tric ef·fect

the property of certain crystalline or ceramic materials to emit electricity when deformed and to deform when an electric current is passed across them, a mechanism of interconverting electrical and acoustic energy; an ultrasound transducer sends and receives acoustic energy using this effect.

piezoelectric effect

[pī·ē′zō·ilek′trik]
Etymology: Gk, piezein, to press, elektron amber; L effectus
1 the generation of a voltage across a solid when a mechanical stress is applied.
2 the dimensional change resulting from the application of a voltage.
3 (in ultrasound) the conversion of one form of energy into another, such as the conversion of electrical energy into mechanical energy.

piezoelectric effect

(pe-a'zo-e-lek'trik)
In ultrasound, a change of the mechanical action of ceramic crystals into an electrical impulse and vice versa.

The three different strains would possess three substantially diferent levels of the piezoelectric effect and would thus emit three different quantifiably detectable voltages.
This generates the corresponding direct or inverse piezoelectric effect.
It is also known that when a drawn PLA film is laminated, the piezoelectric effect increases" the company says.

The piezoelectric effect already finds wide applications in many devices, such as the ignition source for cigarette lighters and for igniting propane-barbecues through the push-start process, as well as in several types of scientific instruments.
The piezoelectrical effect is reversible in that materials exhibiting the direct piezoelectric effect (the product of an electric potential when stress is applied) also exhibit the reverse piezoelectric effect (the production of stress and/or strain when an electric field is applied).
The boulder, which was allegedly accidentally damaged by workmen in the park some time in the past, has a streak of quartz running through it, and some think this element occasionally creates an aura of light around the rock through the piezoelectric effect, whilst others claim the halo of the Greenstone has its origins in the supernatural.
The piezoelectric effect is used in one of two ways: applying a mechanical stress to piezoelectric materials produces an electrical charge; or conversely, an applied electrical charge produces a mechanical strain or motion in a piezoelectric material.
