Chinese Abstract

本研究探討各種氣動式微流體驅動系統。微流體指各種存在於微晶片管道內的流體,氣動式驅動方法指利用外接壓縮空氣通過特殊設計之流道而產生低壓或高壓,來驅動微流體的方法。該驅動裝置若只能產生吸力或只能產生斥力,則微流道之兩端都必須連接驅動裝置以進行雙向驅動,若該裝置能產生吸力也可產生斥力,則微流道只需在一端連接驅動裝置即可進行雙向驅動。本研究將以計算流體力學為分析工具,研讀元件設計的參數變化,提出新的改良設計;最後本研究將製作1mm寬深的微流道以及公分級的驅動元件,以實驗來驗証各種設計的可能性。

English Abstract

This research studies the design of pneumatic driving systems for bidirectional flow control in microchannels. A pneumatic driving system uses an external air compressor as the power source. It induces a pressure difference across the microchannels by driving compressed air through specially designed air passages. The pressure difference provides either a suction force or an exclusion force to drive the microfluid in the channel. If the driving system is capable of generating only one kind of force, either suction or exclusion, then both ends of the microchannel must be connected to a driving unit in order to acquire bidirectional flow control. If the driving is capable of generating both kinds of force, then the microchannel requires only a single driving unit at one end for bidirectional flow control. The research uses computational fluid dynamics as a tool to examine the various geometric parameters of pneumatic driving systems. New designs are proposed based on the computational results. Finally, experiments are conducted on microchannels of 1 mm × 1 mm cross section to verify the validity of the new designs.
