Jiakang Composite Piezoelectric Ceramics

Jiakang Composite Piezoelectric Ceramics Because the acoustic impedance of the piezoelectric ceramic differs significantly from that of air, water, or organisms, the acoustic wave is difficult to incident. To address this issue, a variety of resins are mixed with piezoelectric ceramic. After the composite, the piezoceramic acoustic impedance is low, with good incident characteristics, and the ceramic volume ratio may be modified to control piezoelectric capabilities.
