Performance of piezoelectric ceramic material

Performance of piezoelectric ceramic material is maturing, piezoelectric plate price is making it a functional piezo ceramics get the most widely used type of material. Not only used in industrial and commercial products, such as ceramic filters in the telecommunication equipment,piezo requency discriminators, piezo attenuators; underwater acoustic transducers and detectors for underwater communications and torpedoes; piezo plates and blocks is radar, televisions, computers ceramic transformers and ceramic surface wave devices, but also in the military also received a large number of applications, such as the piezoelectric ceramic transducer , you can smooth underwater navigation, communications, reconnaissance enemy ships, clean the enemy cloth mines. Piezoelectric ceramics can precisely ignite for detonating armor shells and other lethal weapons. In addition, piezoelectric vibration sensor is widely used in precision measurement, navigation, ultrasonic testing, ultrasonic cleaning, ultrasonic diagnosis and so on.With the development of Surface Mount Technology (SMT), functional piezoelectric plate sensor as for components are gradually required to be multi-layered, integrated with chip components, which integrated with analog and multi-functional components. At present, the latest research of rectangle shape piezo plates is a hot issue .how to achieve the multi-functional integration of piezoelectric ceramics, it is the new integrated, intelligent and miniaturized piezoelectric devices. The laboratory has also made some progress in this respect, realizing a new type of acoustic and vibration control device is combining piezomagnetic material with electrorheological fluid which adapt to active vibration control.strong vibration isolator and aerospace, piezoelectric electricity generation has rapid braking control of power machinery ; the need of anti-vibration (anti-vibration and anti-vibration) of nuclear facilities is medical care and bridge engineering; and the use of anti-infrasound and blast shock wave.
