Fabrication and Performances of 1-3-2 Piezoelectric Ceramic/Polymer Composite

Keywords： 1-3-2 piezoelectric composite

A novel 1-3-2 piezoelectric composite has been developed, which consists of piezoelectric ceramic plate and 1-3 piezoelectric composite. The composite was fabricated by dicing PZT ceramic along mutual perpendicular two directions and then filling epoxy into grooves. The piezoelectric and electromechanical properties of the novel composite were determined.The results show a coefficient d33 of 405 pC/N, a vibration displacement of 113.5 pm, an acoustic impendence of 13.3 Mraly,a bandwidth of 12 kHz and a thickness electromechanical coupling coefficient of 0.56.
