What are Typical Piezo Transducer Materials?

Piezoelectric material is a kind of crystal material which appears voltage between two ends when subjected to pressure.Piezoelectric ceramics refers to piezoelectric polycrystals. Piezoelectric ceramic is a polycrystal formed by mixing, molding, sintering at high temperature, irregularly assembling the fine grains obtained by the solid phase reaction and sintering process between the powder particles with the necessary components. Such as: barium titanate BT, lead zirconate titanate PZT, modified lead zirconate titanate, lead niobate, lead lithium barium niobate PBLN, modified lead titanate PT and so on. The successful development of such materials, to promote the sound transducer, piezoelectric sensor performance of various piezoelectric devices to improve and improve.

Piezoelectric polymer material and flexible material, low density, low impedance and high voltage constant (g) has attracted worldwide attention, and the development is very rapid, acoustic ultrasonic measurement, pressure sensor, ignition and Application..

Piezoelectric Composite materials have been widely used in the water acoustic, electro-acoustic, ultrasound, medical and other fields . If it is made into a hydroacoustic transducer, not only has a high hydrostatic response rate, but also impact resistance, is not easily damaged and can be used with different depths.

Due to the ability of producing a ceramic transducer in numerous sizes and shapes, ceramic transducers can be easily adapted to a wide variety of industrial applications. Consequently, they allow for complete customization to meet a customer’s specific needs. Today, the most commonly used ceramic transducer manufacturing materials are lead zirconate titanate compositions, a trend that traces its origins to the 1960s. As ceramic transducer technology has continued to evolve, the use of piezo-polymers and composites has likewise gained acceptance.
