...Henry D. Davis; James G. Harkness; Isa M. Kohls; Brian D. Jensen; Richard Vanfleet; Nathan B. Crane; Robert C. Davis High-temperature microfluidic devices (such as gas chromatography microcolumns) have traditionally been fabricated using photolithography, etching, and wafer bonding which allow...

... desktop surface texturing system is proposed for efficiently and economically fabricating microchannels on the surface of thin sheet material for microfluid and friction/wear reduction applications. Both the experimental and numerical studies were employed to analyze the problems of the flatness...

... of four μ IM parameters, melt temperature, mould temperature, injection speed, and packing pressure on these three pressure-related process parameters was investigated. A design of experiment study was conducted by moulding a test part, a microfluidic component, in three different polymer materials, PP...

...Thor Eusner; Melinda Hale; David E. Hardt Polymeric substrates have significant advantages over silicon and glass for use in microfluidics. However, before polymer microfluidic devices can be mass produced, it must be shown that the manufacturing method used to create these devices is robust...

...), and overall stiffnesses of 32 N ∕ μ m ( X -axis) and 36 N ∕ μ m ( Y -axis). A comparison of microfluidic channels manufactured with a micromachine tool (mMT) alone and with the stage stacked on the mMT shows an improvement in feature accuracy from 870 nm to 170 nm . The stage is integrated...

...Bong-Kee Lee; Chul Jin Hwang; Dong Sung Kim; Tai Hun Kwon In the present study, replication of flow-through microfilters in the newly developed microfluidic lab-on-a-chip for blood typing by microinjection molding process was experimentally investigated. As a precise replication of the microfilters...

..., the pressure drop through the finished microchannel is 23.5 mmHg, which is 26.7% of the pressure drop through the unfinished microchannel (87.9 mmHg). From this result, it was verified that the proposed surface-finishing process using the MR fluid significantly improved performance of the microfluidic channels...

...Hyun-Wook Kang; In Hwan Lee; Dong-Woo Cho, Professor, Member ASME As it is difficult to construct a microfluidic system composed of micromixers, microchannels, and/or microchambers in a single process, an assembly process is typically used. Using microstereolithography technology, however...
