The application range of piezoelectric ceramics can be roughly divided into piezoelectric vibrators and electro-acoustic transducers. The former, such as piezoelectric power generation,oscillators and filter oscillators, mainly use the method of inputting electrical signals from the electrical terminals. The latter, such as microphones and ultrasonic transducers, are mainly used for energy conversion. With the development of piezoelectric ceramic material modification, piezoelectric ceramic transducers will play a greater role in measuring instruments, piezo ceramic generator,ultrasonic metering, underwater acoustic transducers and medical instruments.
Piezoelectric ceramic transducer have the advantages of rapid response, high resolution, high displacement resolution, proportional displacement and voltage, small size, low electromagnetic noise, and high energy conversion efficiency. At present, piezoelectric sensor working is mainly used in piezoelectric switches, relays, piezoelectric pumps, valves, piezoelectric inkjet printers, piezoelectric scanners, piezoelectric buzzers, etc. Piezoelectric inkjet printers utilize the strain and displacement of a piezoelectric actuator element under the action of an electric field to generate a hydraulic pulse in the ink in an airtight container, piezometer for therary device eject it from a nozzle, and print out text or graphics on paper. Commonly used actuating elements are round tube
