By using the inverse piezoelectric effect of the piezoelectric ceramic, precise displacement control can be conveniently realized to form a piezoelectric ceramic actuator. In recent years, the research and application of piezoelectric ceramic actuators has developed rapidly, and has formed an import

Pzt piezo ceramic actuators can be fabricated by using the inverse piezoelectric effect of piezoelectric ceramics, and are used in the automotive field to drive electric rearview mirrors, electric windows and doors, power seats, and the like. This kind of driving can greatly reduce the volume of the

In the past 20 years,piezoelectric crystal cost has developed rapidly at home and abroad. Due to their advantages of simple production, low cost and good stability, they have been widely used in the fields of electronics, light, heat and acoustics, and have a wide range. Ultrasonic transducers are m

Since the curie brothers discovered the piezoelectric effect of tourmaline in 1880, piezoelectric science has officially entered the stage of human science and technology civilization. Early theoretical research was mainly done by the curie brothers later. In 1881, the curie brothers verified the in
