Energy harvesting, which can translate the wasted vibration energy into electric energy, is now a hot topic in the field of new energy, and the key point is to design high power piezoelectric ceramic according with the requirements of low-frequency vibration energy harvesting. In this study, high quality Co-modified 0.2Pb(Zn-1/ Nb-3(2/3))O-3-0.8Pb(Zr0.50Ti0.30)O-3 (PZN PZT + Co) ceramics have been prepared by the two-stage method, and the energy harvesting characteristics were investigated. The results showed that the hierarchical nanodomain structure boosts the strong piezoelectric activity, leading to the high energy harvesting performance. The PZN PZT + Co ceramic sintered at 1000 degrees C exhibits an excellent d(33) x g(33) value of 14080 x 10(-15) m(2)/N, which are much larger than that of commercial PZT-based ceramics. In the mode of the cantilever-type energy harvester, the output voltage and energy density of 33 V, 4.4 mu W/mm(3) were obtained at a low resonance frequency of 85 Hz and acceleration of 10 m/s(2), showing potential application in piezoelectric energy harvester.
