Make Your piezoelectric transducer A Reality

The application of high temperature piezoelectric ceramic materials has a very wide range of piezoelectric rings sensor , but also the hot spots at home and abroad. From the existing research situation, although the non-perovskite piezoelectric ceramics have a higher Curie temperature, but the piezoelectric ultrasonic plate transducer is lower; and perovskite structure of piezoelectric ceramics due to its excellent piezoelectric ferroelectric properties has a more extensive application, but also the main direction of piezo sounder transducer. On the one hand, the new material system can be developed according to the relationship between the tolerance factor and the curie temperature. For example, BiInO3 and BiYbO3 should have a higher curie temperature than BiScO3; on the other hand, they can be guaranteed by doping modification and process improvement structure stability and improve its performance of piezoelectric tubes underwater communication. At the same time, with the miniaturization of electronic components, integrated development trend, high-temperature piezoelectric thin film material will also become the future research hot spots. It is also the direction of future efforts to develop the piezoelectric film with high performance and high curie temperature.piezoelectric cylinder transducer is using the existing piezoelectric ceramic system to study the variation of material properties after thinning. In short, with the continuous development of industries such as automobile and aviation, more and more urgent practical needs piezoelectric tube sensor are constantly putting forward higher requirements on the performance of high-temperature piezoelectric ceramics, which needs the joint efforts of all researchers.
