Abstract

Structural and piezoelectric properties of Pb(Zr 0.54Ti 0.46)O 3+0.2wt% Cr 2O 3+1.0wt% Nb 2O 5 (PZT-CN) thick films were investigated for potential use in energy harvesting device applications. The PZT-CN thick films, fabricated by a conventional tape casting process, were successfully synthesized at a sintering temperature of 1100°C. The sintered film exhibited excellent piezoelectric properties of d 33=365pC/N, γ 33 T/γ0=1069, and k p=0.52. Its d 33·g 33, which can characterize this material as a energy density material for energy harvesting device applications, was excellent, being as large as approximately 14,072×10 -15m 2/N. It was also demonstrated that a unimorph cantilever using the PZT-CN film could generate a significant power of 17.3mW (2083μW/cm 3) for high performance energy harvesters.
