Development and application history of piezoelectric ceramics


In 1881, the Curie brothers experiment verified the inverse piezoelectric effect and gave the same positive and negative piezoelectric constants for quartz. In 1894, Voigt pointed out that crystals of only twenty point groups without symmetry centers are likely to have a piezoelectric effect. Quartz is a representative of piezoelectric crystals, and it has been applied.


 In World War I, the survivor of Curie, Lang Zhiwan, first used the piezoelectric effect of quartz to make an underwater ultrasonic detector for detecting submarines, thus uncovering the history of piezoelectric applications.


The epoch-making progress of piezoelectric materials and their applications should be attributed to the discovery of BaTiO3 ceramics in the Second World War. In 1947, Roberts of the United States applied high pressure on BaTiO3 ceramics to obtain the voltage of piezoelectric ceramics. Japan has carried out research on the application of various piezoelectric devices such as ultrasonic transducers, high-frequency transducers, pressure sensors, filters, and resonators using BaTiO3 piezoelectric ceramics. This research has been carried out until the mid-1950s.


In 1955, B. Jaffe et al. found that PZT piezoelectric ceramics, which are superior in piezoelectricity to BaTiO3, have greatly advanced the application of piezoelectric devices. Some applications that are difficult to be practical in the BaTiO3 era, especially piezoelectric ceramic filters and resonators, have been rapidly put into practical use with the advent of PZT, and SAW filters, delay lines, and oscillators have been applied. The device was also put into practical use in the late 1970s.
