چکیده انگلیسی
In order to collect energy from human activities, piezoelectric energy harvesters should have a flexible structure, low resonant frequency and wide frequency bandwidth. In this paper, the fabrication and characterization of a metal-based Pb(Zr,Ti)O3 (PZT) bimorph thick film energy harvester. PZT thick films were deposited on cantilever-shaped titanium (Ti) substrate via a dip-coating process. The electrical properties of the PZT films sintered at different temperatures were investigated. The nonlinear piezoelectric energy harvester has the following advantages: it is suitable for low frequency, weak vibration, and wide frequency bandwidth. The maximum open-circuit voltage of the piezoelectric energy harvester is 1.6â¯V and the output power is 0.85â¯Î¼W with 150â¯kΩ load resistance at low resonant frequency of 17.6â¯Hz when the input vibration acceleration was 0.12â¯g. In addition, the frequency bandwidth is broadened from 0 to 8.4â¯Hz as the input acceleration increases from 0.05â¯g to 0.12â¯g.
