• Piezoelectric ceramics is one of those information functional ceramic material that can convert mechanical energy and electricity to each other-piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and have been extensively utilized in medical imaging, Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made by utilizing their materials to cause relative displacement of the great and damaging fee facilities contained within the material below the motion of mechanical stress, resulting in polarization, resulting in the alternative signs of sure costs performing on either ends of the material, that is, the piezoelectric effect. It has sensitive characteristics. Ceramics are mainly used to fabricate ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, excessive voltage generators, infrared detectors, surface acoustic wave devices, electro-optical instruments and In addition to being used in high-tech fields, piezoelectric ceramic are used to serve humans in daily life and work hard to create a more in-depth existence for people ceramics Alumina ceramics is largely probably the most widely used, most versatile, and ideal ceramic materials among oxide ceramics voltage is applied to piezoelectric ceramics, it's going to produce mechanical deformation with adjustments in voltage and frequency. On the alternative hand, when the piezoelectric ceramic is vibrated, an electric payment is generated. Using this principle, when an electrical sign is utilized to a vibrator composed of two piezoelectric ceramics or a piezoelectric ceramic and a metallic sheet, the so-called bimorph element, ultrasonic waves could be emitted due to bending vibration. On the contrary, when ultrasonic vibration is utilized to the piezoelectric bimorph element, an electrical sign is generated. Based at the above effects, piezoelectric ceramics can be utilized as ultrasonic sensors ceramics are handy ceramic materials which will mutually convert mechanical calories and electric energy, and belong to inorganic non-metallic materials. At an identical time, it has a good and unfavorable piezoelectric effect. The piezoelectric ceramic wafers produced via approach of Changzhou Ultrasonic Electronics Co., Ltd. are mainly utilized in the fields of ultrasonic probes, ultrasonic clinical treatment, ultrasonic flowmeters, and automatic control. With ideal functionality and total specifications, PZT piezoelectric wafers and new composite piezoelectric wafers can meet different types of needs.
