When an electric field having the same polarity and orientation as the original polarization field is placed across the thickness of a single sheet of piezoceramic, the piece expands along the axis of polarization (thickness direction) and contracts perpendicular to the axis of polarization (length and width direction). The motion in the thickness direction is on the order of tens of nanometers. Motion in the length direction is typically on the order of microns or tens of microns.
Please note: These sheets are thin, brittle ceramic. For a more robust product, you may want to consider our robust standard piezo benders and extenders, or even consider customizing a piezo to assist your prototyping. Piezo sheets are the fundamental building blocks of piezo devices - check out their Material Properties.
The polarization mechanism of piezoelectric ceramics
depends on its internal structure. Piezoelectric ceramics are made of many small grains irregularly "inlaid". Each small grain can be seen as a small single crystal, in which atoms (ions) are arranged regularly (periodically) to form a lattice, which is composed of repeated cells. The lattice directions of grains and grains are not necessarily the same, and they are still chaotic and irregular as a whole. In order to keep piezoelectric ceramics in the lowest state of energy (electrostatic energy and elastic properties), there will be a number of small regions in the grains. The spontaneous polarization of cells in each small region has the same direction, but the directions of spontaneous polarization between adjacent regions are different. The area with the same direction of spontaneous polarization is called electric domain, and the whole ceramic includes many electric domains.

After the nuclear tester wears protective goggles made of transparent piezoelectric ceramics, when the light radiation generated by a nuclear explosion reaches a dangerous level, the piezo electric plates in the goggles convert it into instantaneous high-voltage electricity. In 1/1000s, the light intensity can be reduced to only 1/10000, and when the dangerous light disappears, it can return to its original state. This type of goggles has a simple structure and weighs only a few tens of grams, making it very convenient to carry when installed on a nuclear protection helmet.
FBelec can customize products with special requirements according to user
P is the abbreviation of lead element Pb, Z is the abbreviation of zirconium element Zr, and T is the abbreviation of titanium element Ti. (English piezoelectric ceramic transducer). PZT piezoelectric ceramics are polycrystals sintered from lead dioxide, lead zirconate and lead titanate at 1200 ℃. It has positive piezoelectric effect and negative piezoelectric effect. Preparation of Pb (Zr1-xTix) O3 ZrO (NO3) 2 (zirconium nitrate) → ZrO2+NO2+O2 C6H4O7 Ti (titanium citrate)+O2 → TiO2+H2O+CO2 Pb3O4 → PbO + O2 (1-x)ZrO2 + x TiO2 +PbO → Pb(Zr1-xTix)O3
The piezoelectric plate from our side are normally cut from an option of three alternative standard sizes, i.e. Lateral dimensions of 40 x 20mm, 50 x 50mm, and 89 x 42mm. Still larger sizes up to 150mm lengths can be cut from discs. These are designed as per the set industry norms and guidelines.
