The working principle of a piezoelectric actuator is, once the voltage is applied to piezoelectric actuators then they generate a small displacement through a high force capacity, so these are used in many appl
The commonly measured physical quantities by a piezoelectric sensor are Acceleration and Pressure. Both pressure and acceleration sensors work on the same principle of piezoelectricity but the main difference between them is the way force is applied to their sensing element. In the pressure sensor, a...
Piezoelectric devices work on the principle of tranferring energy between electric fields and mechanical forces using ferro-electric materials such as quartz.When the material is compressed or changes shape, its electrical field changes as well. A transducer converts this electrical energy into mechanica...

Crystal oscillator circuit works on the principle of the inverse piezoelectric effect, i.e., a mechanical deformation is produced by applying an electric field across certain materials. Thus, it utilizes the vibrating crystal’s mechanical resonance which is made of a piezoelectric material for genera...
vibrate and generates sound waves, which is the principle of an ion loudspeaker. In order to ionize, the high frequency voltage of the 20MHz is added, while the audio signal is superimposed on piezoelectric. Therefore, the high frequency oscillating ion speaker, modulated audio signal, ...
Piezoelectric Crystal Piezoelectric Transducer The main principle of a piezoelectric transducer is that a force, when applied on the quartz crystal, produces electric charges on the crystal surface. The charge thus produced can be called as piezoelectricity. Piezo electricity can be defined as the ele...
The model adopts the "similarity" principle, where the main variables in the equations describing the pressure of the detonation wave are the weight of the charge and the distance of the hull from the epicentre14. The authors are aware that the similarity equations used do not directly ...

Another principle used in humidity sensing is measuring changes in a conductor’s resistivity. The resistance of nonmetal conductors depends on water content. This concept is used in resistive humidity sensors, also known as hygristors.As shown in the figure, the sensor contains a material with ...
