HIFU Piezoelectric ceramic used for UltraShape

Piezoelectric ceramic material as the core component of the ultrashape realizes the conversion between electrical energy and mechanical energy. The performance of the piezoelectric ceramic material directly affects and restricts the output performance of the ultrashape . Although the existing hifu piezo ceramics can basically meet the practical application of ultrasonic motors, with the continuous development of piezo ceramics in the application fields of robots,ultrashape , aerospace, and weaponry, the requirements for the use of hifu piezo ceramics transducers in different environments are also increasing. 

The more is demanding,Japan has a leading position in the research of ultrasonic motors. The piezoelectric ceramics are used for mainly Panasonic Group's PCM series products, which have large k and e. The motor can realize low voltage drive and large output force. The research is mainly based on military and large-scale weapons applications. It is mainly based on the hard PZT hifu piezoelectric sensor produced by Vemita-on, including the high sensitivity of PZT-5, PZT-8 and PZT-5. The stability is good, but PZT-8 material has low field loss and high power density. based on the protection of the environment, it is the development of non-lead piezoelectric ceramic for UltraShape , including perovskite-based piezoelectric ceramics and piezoelectric layered piezoelectric ceramics, their components are located near the quasi-homogeneous phase boundary solid solution, optimized its piezoelectric coefficient can exceed 300 pC/N, it is close to Pzt material.

Its Curie temperature of high focus piezo sensor can reach above 200°C, and it is more suitable for brakes and high-power devices including ultrasonic motors. As a big country in the production and application of piezoelectric ceramics, a series of high-power piezoelectric ceramics have also been used in ultrasonic motors and have been applied in standing wave ultrasonic UltraShape. The rotational speed can reach 300 rpm and the torque is 1 kg. Driving voltage of high focus piezo crystal is 20 V. At the same time, the company is developed by the performance of a typical PZT-8 hard material piezo ceramic for UltraShape.
