Harbin Core Tomorrow(CoreMorrow for short) provides piezoelectric components, which could be widely selected in terms of shape and size to suit your application.
CoreMorrow piezoelectric ceramics (also often called ultrasonic ceramics) contains only one piezoelectric ceramic layer inside, and there is no electrode layer inside, only the electrode layer on the outer surface, unlike the multilayer piezoelectric ceramics, there are many ceramic layers and electrode layers. It could be used for cutting without destroying the single-layer ceramic corresponding to the positive and negative electrodes.

After the piezoelectric ceramics are installed in the equipment, the resonant frequency will be reduced, and the specific parameters need to be structured.
Displacement CALA.
Using the inverse piezoelectric effect, that is, applying a voltage to the piezoelectric ceramic, the piezoelectric ceramic will be deformed and displaced under the influence of the electric field.
1、Displacement cala.
Displacement of piezoelectric ceramic under the withstand voltage is about 1‰ of the length of displacement direction. For example, 1mm thick ceramic sheet has a withstand voltage of 1000V, and at 1000V, its displacement is about 1μm.
2、Plate piezo ceramic displacement cala.
U：voltage[V] ， H：height of piezo ceramic[m] ， E：electric field intensity[V/m] ， d：piezoelectric coefficients[m/V] ， W：width of piezo ceramic[m]
It can be seen from the above formula that the displacement of piezo ceramics is only related to the material and the driving voltage, and for the same material and different heights of piezo ceramic, as long as the same voltage is applied (Note: the voltage cannot exceed the voltage that it can withstand ), the resulting displacement is basically the same.
The displacement of other shapes can also be estimated according to this calculation formula.
Static Voltage CALA.
When the piezoe ceramic is used as a sensor, its positive piezoelectric effect is used, that is, it is deformed by applying an external force to output electric charge.
Disc static voltage cala.:
g33：material constant,
F：froce,
OD：outer diameter,
ID：inner diameter
