About piezoelectric ceramics, piezo ceramics generate the DC or AC ? In addition, is it generically a piezoelectric polycrystal?
Piezoelectric ceramics produce the direct current, not alternating current. In addition, it belongs to inorganic piezoelectric materials, and this kind material can be divided into piezoelectric crystal and piezoelectric ceramic. Piezoelectric crystals generally refer to piezoelectric single crystals, while piezoelectric ceramics generally refer to piezoelectric polycrystals.
2.About P8 material piezoelectric ceramic , what does it mean?
About P8 material piezoelectric ceramic , which specifically refers to the piezo ceramic,it is of high power. In addition, we should also know that P4 material piezoelectric ceramic refers to both transmission and reception, P5 material piezoelectric sensor refers to detection drive, P6 material refers to high stability, and P7 material refers to high frequency and lead titanate. Moreover, there are certain standards for naming specifications, and the above-mentioned ones are roughly equivalent to their units.
3.What is the voltage and current of piezoelectric ceramic generated on the lighter?
The ultrasonic piezo ceramic element on the lighter is deformed by an external force to generate voltage and current instantaneously, it is in the specific values: the voltage generated by the piezoelectric ceramic, the range of which is 4000-6000V, but there are also tens of thousands of volts. The current it produces is relatively small, only a few microamps.
4.What is the dielectric property of piezoelectric ceramics?
