Proc. ASME. IMECE2020, Volume 12: Mechanics of Solids, Structures, and Fluids, V012T12A031, November 16–19, 2020
Paper No: IMECE2020-23957
...Abstract Abstract This study reports the design, fabrication, and a two-dimensional numerical analysis to identify the optimal operating parameters of a novel microfluidic co-culture platform with an integrated pressure-controlled valve. Replica molding using 3D printed PDMS molds were used...

Proc. ASME. IMECE2019, Volume 3: Biomedical and Biotechnology Engineering, V003T04A008, November 11–14, 2019
Paper No: IMECE2019-11545
.... Upon completion of pattern printing, the samples were then encapsulated in polydimethylsiloxane (PDMS) and cured; formed microchannels were then characterized via micrographic image analysis. The results show that three gels, 2% w/v agarose gel, 7.5% w/v gelatin gel, and a mixture of 2% w/v agarose gel...

Paper No: IMECE2019-12187
... Abstract The nanoindentation response of polydimethylsiloxane (PDMS) is examined using single nanoindentation loading and small-scale fatigue. It is well known that viscoelastic material response is inherently related to the local loading and environmental conditions. First, quasistatic...

... sensitivity, selectivity, time response, and operating life-span. This paper will analyze the electrical resistivity of the sensor relative to the percentage of different type of particles in PDMS matrix in order to understand the effect of corrosion mechanism on metal particle polymer composites. This paper...

Proc. ASME. IMECE2003, Microelectromechanical Systems, 369-372, November 15–21, 2003
Paper No: IMECE2003-41213
... This paper presents two types of novel micro check valves that are based on PDMS. The valves consist of a thin flap and a flow restriction block inside a microchannel. The flap is perpendicular to the flow and lies near the block, which forms a restricted fluid path inside the channel...
