pi·e·zo·e·lec·tric effect

The generation of an electric charge in certain nonconducting materials, such as quartz crystals and ceramics, when they are subjected to mechanical stress (such as pressure or vibration), or the generation of vibrations in such materials when they are subjected to an electric field.

One, called the 'piezoelectric effect,' occurs when vibrations in certain materials generate an electrical charge.
Piezoelectric materials have a unique characteristic of reversibility which allows them to exhibit direct as well as converse piezoelectric effect. While exhibiting direct piezoelectric these materials generate electricity when stress is applied, whereas during converse piezoelectric effect these materials generate stress when electric field is applied.
The direct piezoelectric effect, that is, conversion of stress/strain into surface charges, has been widely used in sensor devices with new applications in piezoelectric energy harvesters [6-8] whereas the inverse piezoelectric effect could be used for actuator devices [9-11].
Sodium Potassium Tartrate exhibits a piezoelectric effect and finds application in many piezoelectric devices.
Piezomotors are devices in which mechanical movement is achieved due to the inverse piezoelectric effect. The materials that form the basis of such drives are called piezoelectrics.
[ClickPress, Mon Nov 12 2018] Piezoelectric actuators are electromechanical motors that convert electrical energy into mechanical stress or displacement using the piezoelectric effect. Piezoelectric actuators are known for their precise movement control and hence, are highly used for finely adjusting mirrors, lenses, machining tools and in other equipment.
Electrical energy, generated by piezoelectric effect of piezoelectric ceramics, can be efficiently dissipated by external electronic circuits [5].
where [d.sub.31] and v(t) are the coefficients of the converse piezoelectric effect and the applied voltage, respectively.
The piezoelectric effect states that when a mechanical stress is applied to certain ceramics and crystals, an electrical charge is generated.
