Piezoelectric cylinder transducer

Piezoelectric cylinder transducer

Piezoelectric cylinder transducer Information:

The piezoelectric effect mechanism of piezoelectric cylinder transducer is very different from that of quartz crystals.

Electroceramic materials will not produce piezoelectric effect. After the piezoelectric ceramic is polarized, the remaining poles.

The intensity of polarization will cause bound charges to appear at the two ends perpendicular to the polarization direction (one end is positive, the other end is negative), due to the effect of these bound charges on the two surfaces of the ceramic, one layer comes from the outside.

The free electric charge of the world, and make the whole piezoelectric ceramic sheet be electrically neutral. When an external pressure parallel or perpendicular to the polarization direction is applied to it, the piezoelectric ceramic sheet will be deformed, the distance between the charge-bound layers within the sheet will become smaller, and the bound charge on one end will have an opposite sign on the other end. Enhance, and make the surface free electric charge surplus appear discharge phenomenon. When the external force received is a pulling force, a charging phenomenon will occur.
