Piezoelectric ceramic materials and applications：
The research and development of the dielectric material has become an industrial field and a subject field, which was formed in the 20th century with the development of the electrical industry.
The international dielectric discipline was formed in the 1920s and 1930s. The landmark events were: the Institute of Electrical and Electronics Engineers (IEEE) started the International Insulation Media Conference in 1920 and later the corresponding chapter (IEEE Dielectric and Electrical Insulation Society). The United States MIT established a research laboratory led by Professor Hippel. Leningrad University, the Soviet Union established a professional electrical insulation and cable technology, Moscow Institute of Technology established a dielectric and semiconductor professional.
In particular, Professor DeBai in Germany obtained the Nobel Prize in the 1930s for the study of the relationship between polarization and loss characteristics of the dielectric and its molecular structure, laying the foundation for the dielectric physics. With the development of electrical and electronic engineering, the formation of the dielectric physics, dielectric loss, conduction, breakdown as the center of the dielectric physics.
Applications: Bolt-clamped ultrasonic transducer, Ultrasonic Sensor, Vibration Sensor, Pressure sensor, Vibration generation, Biodiesel mixing transducer, Piezo expansion sensor, compression sensor, Piezo Welding, Tonpilz Transducer and others.
