The resonance frequency of 1-3 piezoelectric composites and 2-2 piezoelectric composites materials we produced can be designed from 50 kHz to 2000 kHz. According to the requirements, we can produce multi-function and various shapes piezoelectric composite materials such as rectangle, circle, circular tube and spherical cap structure. So far, the piezoelectric composite materials have been widely applied to the preparation of acoustic transducer、nondestructive testing probe and ocean detection sensor, etc.
