DEVELOPMENT AND APPLICATION OF PIEZOELECTRIC ACTUATION AND CONTROL

The piezoelectric actuator is a kind of device which gets the mechanical actuating or controlling ability by use of inverse piezoelectric effect of the piezoelectric material. The device, actuated and controlled by the piezoelectric material, gets the simple structure, prompt reaction and the wide concern of the scientists, just because of the advantages of the piezoelectric material, such as rapid reaction, high precision, the ability against interfering. At present, the developed devices with piezoelectric actuation and control are mainly ultrasonic motor and precise actuator etc, widely and successfully used in the national defence, the biomedicine, the photoelectron and so on many fields. The research actuality and application in this fields are introduced. Some representative device examples are given here. And there are some evaluations about the relational performance .
