We present a new microfluidic system for transdermal interstitial fluid (ISF) extraction, collection, and volumetric measurement towards the application of noninvasive, continuous, and real-time glucose monitoring. This device consists of a Venturi Tube for vacuum generation, chambers for the introduction of ISF and normal saline solution, pneumatic valves for fluid control, and flow sensors for ISF...
We present a microfluidic volumetric measurement system for applications involving conductive fluids. The low cost polydimethylsiloxane (PDMS) device consists of an interconnected Venturi Tube to generate vacuum for fluid manipulation, and a resistance based sensor for fluid volume quantification. The Venturi Tube achieves less than 88 kPa (absolute pressure) vacuum when a 256 kPa external pressure...
