A dense PZT thick film with a thickness of 10 μm was prepared on a stainless steel substrate using a SolGel technique.The effects of annealing conditions on the crystallization of thick films were investigated.X ray diffraction analysis showed that the pure perovskite phase of the PZT thick films was obtained after annealing at 700 ℃ with 20 min.The electrical properties of the films showed that the residual polarization (Pr) was 7.5 μC/cm2,the coercive field strength (Ec) was 7.2 V/μm,and the piezoelectric constant (d33) was 73 pC/N.A vibration energy harvester with piezoelectric cantilever structure of length of 20 mm and width of 4 mm was designed and manufactured. The output performance test results showed that the vibration frequency was 95 Hz,the collector output voltage was the highest,and the output voltage value was 862 mV.
