The harvester is operated by converting the low frequency of waves to mechanical oscillation with higher frequency, and the mechanical oscillation can able to excite the flexible piezoelectric composite film to generate electric power finally. The frequency-up conversion mechanism designed in this study includes a rack and a combination of a large gear and two small gears with a crankshaft mechanism. The purpose of the rack is to turn the vertical wave motion into mechanical rotation; the purpose of the gear group is to increase the rotation speed, and the crankshaft mechanism combined with the gear group, the combination mechanism can turn the rotation to the vertical mechanical oscillation with a stable displacement. This harvester is measured by experimental, in the wave period 1s and wave height parameter is 100mm, this piezoelectric wave harvester can produce the mechanical oscillation with nearly 7Hz, and this piezoelectric wave harvester generated a maximum output voltage 2.8V, output current 1.44μA and the maximum electric power 1.37μW. 吳嘉哲 2017 學位論文 ; thesis 90 zh-TW |
