 piezo discs and cylinders is a polycrystalline with piezoelectric properties is an important part of information-functional ceramics. It has the advantages of high electromechanical coupling coefficient, low price and easy mass production. It has been widely used in all fields of social production. Especially in the field of ultrasound of 15khz electrical model piezo disc and electronic science and technology, electrical model piezoelectric discs ultrasound piezoelectric ceramic materials have been gradually dominated by absolute advantages Status, such as medical and industrial ultrasonic testing, underwater detection, piezoelectric transducers, ultrasonic motors, display devices, electronic control multicolor filters. However, in practical components, different applications require different performance parameters of piezoelectric ceramic materials, which force people to make corresponding performance improvement on biomedical applications of cylindrical piezoelectric ceramic materials.At present, there are mainly two methods at home and abroad: one is doping modification, that is, doping with some impurity ions; the other is improving the preparation process.

This article will make a brief overview of the latest developments, research and application of acoustic cylindrical piezoelectric ceramic materials and their development trend. The purpose of 40 Khz acoustic electrical model piezoelectric is to enable relevant scientific research and teaching personnel to pay attention to the new development in this field and the problems to be solved. The biggest feature of piezoelectric ceramics is a positive piezoelectric and inverse piezoelectric. Positive piezoelectricity refers to some of the dielectric medium under the action of external forces, the medium positive and negative charge center relative displacement occurs and cause polarization, resulting in the opposite ends of the dielectric surface of the opposite bound charges, when the piezoelectric Dielectric plus external electric field, the positive and negative center of charge within the dielectric is not only the relative displacement of polarized, at the same time, as a result of this displacement caused by deformation of the dielectric, this effect is called inverse piezoelectricity.
