Recent advancements in 3D printing technology have provided a potential low-cost and time-saving alternative to conventional PDMS (polydimethylsiloxane)-based microfabrication for microfluidic systems. In addition to reducing the complexity of the fabrication procedure by eliminating such intermediate steps as molding and bonding, 3D printing also offers more flexibility in terms of structural design...
This paper presents a combined experimental and numerical simulation study of polydimethylsiloxane (PDMS) pneumatic micropumps. The micropumps consist of three pneumatic PDMS membranes, one pump chamber, and two check valves. In particular, two flow stoppers in fluidic channel corresponding to the check valves can avoid back flow, and increase the flow rate. The flow rates of the micropumps have been...
This paper presents a telemedicine system utilizing an integrated microfluidic chip for fast, automatic detection of insulin. The telemedicine system expedites the insulin assay results digitally from the assay site to medical professionals located off-site, while the off-site specialist can directly provide diagnosis through the Internet. The integrated microfluidic chip contains pneumatic micropumps,...
