Atomizing Piezo Ceramics for Making Humidifier and Atomizer
Application
The piezoelectric element has piezoelectric effect, and the
piezoelectric effect is reversible. The piezoelectric effect is
applied stress in a particular direction along certain crystal,
crystal polarization change, and change is proportional to the
called positive piezoelectric effect, on the contrary and stress
variables, an electric field on the crystal strain and strain
resulted in proportional to the electric field is called inverse
piezoelectric effect. Because of the piezoelectric effect,
piezoelectric element can force, pressure, acceleration,
temperature, quality and other non electrical quantity into
electrical quantity according to certain rules, all kinds of
sensors can be used to produce a detection, to achieve certain non
electrical quantity conversion, control and transmission function,
in the military and civil widely application. The piezoelectric
sensor is the direct use of piezoelectric effect and inverse
piezoelectric effect of piezoelectric material, the former is
charge by the piezoelectric element generated by reflecting the
size or change of measurement, which is measured by changes reflect
changes in the piezoelectric element vibration or deformation.
