本研究設計一陣列式微型混合器，以表面張力做為驅動力，透過
特殊開放式的微流道網絡與混合腔體設計，利用壓力差完成有效定
量、同步且快速的混合效果。晶片中特殊流道的網絡設計，可定量不
同體積比例的二欲混合流體，並利用電濕潤法與流道梯度設計造成的
壓力差將其同時、反向地引流至混合腔體內，其後，利用兩反向流體
造成的介面作用力，在陣列式的混合腔體(250x250x60μm3) 中生成三維渦流，達到體積定量、快速且陣列式同步混合效果。

研究中探討四種不同腔體次結構設計(基礎型、橫閂型、導角型、
改良式橫閂型)與三代陣列式微型混合器對混合效率的影響。逆時針
長橫栓的次結構設計混合效率較佳，其可限制流體進口長度與混合區
域、影響混合介面長度，使兩液體在160ms 內造成均勻且快速的混合；搭配第三代陣列式微型混合器的外部定量設計，可一次多工地完成不同濃度樣品的混合需求。

研究中利用微粒子顯像測速儀觀測混合腔體內部的流場，搭配
CFD-RC 軟體的模擬結果，了解液體在腔體內三維渦流的形成狀況及
物理機制。此外，透過高速流體攝影系統與螢光樣品實驗，了解混合效率。
