Abstract

In this study, piezoceramics/polymer composites with 3-3 connectivity were made by BURPS(Burnout Plastic Sphere) technique with PZT ceramics and PMMA sphere(50 - 80${\mu}m$). And the dielectric and piezoelectric properties dependent on the PZT vol.% were investigated. The dielectric constant($K_{33}$) of 3-3 composites is increased almost linearly with increasing the PZT vol.%, while piezoelectric coefficient($d_{33}$) is slightly increased.
