    Abstract

    (1-x)Pb(Zr0.47Ti0.53)O3-xPb[(Zn0.4Ni0.6)1/3Nb2/3]O3 [(1-x)PZT-xP(ZN)N] ceramics with 0.26≤x≤0.31 were sintered at 1100°C, and their energy harvesters were fabricated. All specimens exhibit a similar energy convergence efficiency. However, the transduction coefficient (d33×g33) increased with x, reaching 21.5×10-15m2/N for the x=0.31specimen; the figure-of-merit of the specimens shows a similar variation. The output energy density of the energy harvester also increased with x, and a high output energy density of 231mW/cm3 was obtained for the harvester fabricated using the x=0.31 specimen, indicating that the d33×g33 value significantly affects the output energy density of the energy harvester.
