1, resonance frequency of ultrasonic piezoelectric ceramicsThe resonance frequency of the ultrasonic piezoelectric ceramic transducer is related to the thickness of the piezo ceramic. After the piezoelectric ceramic is installed in the ultrasonic device, the resonance frequency of the piezo ceramic

Piezoelectric ceramics are a type of crystal material that undergoes a shape change such as compression or elongation when subjected to mechanical stress. As the shape changes, different charges are generated on both sides of the crystal. Conversely, adding a different voltage across the linear piez

Transducer is an important part of sonar. From the perspective of the history of hydroacoustics, every step of the development of underwater acoustics is inseparable from the development of transducer technology. Since hydroacoustic transducers play a key role in underwater acoustic engineering, man

Since the Curie brothers discovered the piezoelectric effect of tourmaline in 1880, the history of piezoelectrics ceramics began from quartz and BaTiO3, ceramics have played an important role in the history of piezoelectrics. However, after the discovery of PZT piezoelectric ceramics, the speed of a

Transducer characteristics and calibration methodsA hydroacoustic transducer is a device that converts acoustic energy and electrical energy each other. The position in sonar is similar to the antenna in a radio, an acoustic system that emits and receives sound waves in seawater. A piezoelectric tra

The polarized PZT piezo ceramic becomes an ordered arrangement due to the polarization electric field forcing the disordered 90°domain and 180°domain steering in the unit cell, and the spontaneous polarization axis in the unit cell is longer than the non-spontaneous polarization axis. When the 90°do

Piezoelectric ceramic round tube is a commonly used for the acoustic transducer unit. It has simple structure, stable performance, convenient layout, uniform directivity along the radial direction and high sensitivity. Therefore, it is mostly used in the fields of underwater acoustics, geology and p

In the 1970s, scientists use piezoelectric ceramic materials(PZT) and non-piezoelectric materials (polymers compound) according to a certain arrangement, thereby forming a combination of piezoelectric materials and non-piezoelectric materials.Piezoelectric composites have their own shortcomings, for

High-temperature thin film flowmeters generally consist of a thermal resistance layer and a thin film thermometer layer. The thermal resistance layer of piezos discs transducer usually uses PZT material with a small thermal conductivity so that the thermometers are on both sides can obtain a large t
