How to judge the positive and negative poles of piezoelectric ceramics? The positive and negative poles of piezoelectric ceramics, to be precise, from a professional point of view, such a device itself is also an electronic component. and there are two copper circular pads, all of which are placed i

1. The dielectric constant should be moderateUsually the dielectric constant is 10 to 1000. If the dielectric constant is too large, it will cause direct coupling between the interdigital electrodes; if the dielectric constant is too small, the impedance will be too large and it will not be easy to

Three elements and principles for high-voltage polarization of piezoelectric ceramics by high-voltage polarization device three elements 1. Polarized electric field Only under the action of the polarized electric field, the electric domain can be aligned along the direction of the electric field, so

Curie temperatureWhen the temperature is higher than the curie temperature (Tc), the piezoelectric ceramic is in the paraelectric phase, and the spontaneous polarization and piezoelectricity also disappear. At the Curie temperature, many physical properties of piezoelectric ceramic materials, such a

Only under the action of the polarized electric field, the electric domains can be arranged along the direction of the electric field, so it is the main factor of the polarization condition. The higher the polarization electric field, the greater the effect of promoting the alignment of electric dom
