The mechanical energy of piezoelectric ceramics is converted into electrical energy. The electromechanical coupling coefficient is not only related to material parameters, but also related to the working mode of specific piezoelectric materials. For piezoelectric ceramics, its size is also related t

Granulation is a process in which a porcelain PZT material parameter is mixed with a binder to prepare coarser particles (about 20 mesh/inch) having good fluidity. This kind of granule is called a pellet to show the difference.1) The role of granulationSince the ground porcelain powder of sensitive

(1) Positive piezoelectric effectIf a pressure F is parallel to the direction of polarization which is applied to the ceramic sheet, the ceramic sheet is compressed, the polarization is reduced, and the free charge of piezoelectric ceramics originally absorbed is released, and a discharge phenomenon

The surface of the original piezoelectric discs sensor substrate is pure white, and the surface color is yellow. There are two possibilities, First, since the surface material of the alumina piezo ceramic is yellowe by chemical corrosion, the chemical property of the alumina is stable, and it is dif

Chemical analysis is one of the most widely used methods for the detection of piezo ceramic materials. It is a kind of thing.A chemical reaction between the masses to achieve a qualitative or quantitative study of the material. In the analysis process, the chemical composition of the substance can b

The ultrasonic transducer is a sound pressure-electrical conversion device that can convert the surface acoustic energy and electrical energy.Since 1917, the French scientist Paul Langevin discovered the inverse piezoelectric effect, it is using quartz crystals as piezoelectric materials.The first p

We designed the three-dimensional spherical array of geometric model-spherical crown array model. In other words, using the adjacent triangles as the modeling material, a finite shape is established.A geometric model of a spherical crown array is composed of planar regular hexagonal elements of the

piezoelectric ceramic disc transducerIn order to meet the control requirements of flexibility, rapidity, and simplicity, the domestic and foreign scientific and technological communities and industry have been working on various new types of micro-motors for many years. A

what is the use of piezoelectric sensorPiezoelectric transducers use the piezoelectric effect and inverse piezoelectric effect of piezoelectric ceramics to realize the mutual conversion of electrical energy and acoustic energy. Piezoelectric ultrasonic transducers

piezoelectric ceramics crystal for ultrasonic motorBecause of its low energy consumption, fast response, high rigidity, and easy control, piezoelectric ceramic materials can be affixed to the surface of the body structure or can be embedded inside the body structure, and
