摘要: 本文是探討利用卡門渦列作用驅動來收集能量的微流道結構,此能量收集器的主要動作方式系由以一穩定的流體流入流道內,並在流道內製作一半橢圓型阻擋物,藉由水流流過此阻擋物而在其後方流場引發卡門渦列作用以產生具有固定頻率之振動。 在製程方面,本研究採多層結構堆疊出流道,以負光阻(JSN126N)製作微流道後利用聚二甲基矽氧高分子(Polydimethylsiloxane, PDMS)作為振動薄膜貼在流道表面上,利用水通過流道時聚二甲基矽氧高分子薄膜所產生的變化來量測所產生的震動位。 但由於微流道的障礙物是利用光阻所製作出來的,當流道注水時相當容易造成毀損影響量測時的數據,所以我們利用雕刻機製作一兩倍尺寸的壓克力微流道,並利用此流道量測來證實本文所設計的微流道概念是可行的。
In this study, the Karman Street was used to harvest the energy from the microchannel structure. The movement of the energy harvester is from the stable fluid flow through a semi-oval baffle which was made in the channel and the flow distribution triggers the Karman Street to yield vibration with constant frequency. The channels were fabricated by multilayer structures. After using negative photoresist to fabricate the microchannel, a polydimethylsiloxane (PDMS) membrane was pasted on the surface of the microchannel and the vibrational potential was measured using the water flow through the polymer membrane to yield the variation of the potential. The measured data was easily damaged when the micro-fluidic channel was full of water because the baffle was made by photoresist. Therefore, we fabricated an acrylic microchannel with one to two times bigger by a carving machine and the concept of micro-fluidic channel was feasible using the measurement of this study.
