摘要

本研究所提出的創新的Self-Alternation Magnetic-Flux (SAMF）和三維堆疊線圈結構(3D-coils)的設計具有重現性、元件尺寸微縮的可能性及寬頻偵測震盪頻率之高靈敏度的能源採擷器(Energy Harvester)。創新的SAMF結構可使振動擷取器擁有高靈敏度與較寬的操作頻率1Hz∼1kHz與非常短暫的暫態時間 < 0.25μsec；同時也證明我們所提出的三微堆疊線圈結構於1Hz外加震動訊號的條件下，元件輸出電壓量2~9.08(mv/coil)比先前的發表輸出電壓量(~1mV/coil)來的高，證明可在固定元件面積下來達到提升元件的輸出電壓量。因此，所設計之能源擷取器有潛力擁有較多的應用層面例如人體走動、汽車行駛間的晃動等等。

In this study, we report a reproducible, highly scalable, and highly sensitive broadband 1Hz~1kHz vibrated energy harvester with innovated self-alternation magnetic-flux (SAMF) and 3D-coils designs. High sensitivity of 2~6 mV/coil at very wide frequency range of 1Hz ~ 1kHz than previous reports (~1 mV/coil), small magnet volume of 132 mm3, and the very fast transient time of < 0.25 ?sec are achieved due to innovated SAMF. Meanwhile, we also demonstrated 3D-colis stack-ability for output voltage enhancement. This vibrated energy harvester thus offers high potential for several kinds of applications, such as human motion, automotive etc..
