Experimental Studies on the Capillary Flow Phenomena in Polyimide Based Glass Microfluidic Devices
Abstract: The polyimide based glass microfluidic devices are fabricated using the maskless lithography. Water is the only working liquid in this work. The effects of micropillar side length, microfluidic friction and surface area to volume ratio on the surface-driven capillary flow of water are studied experimentally. The surface-driven capillary flow of water is slower due to higher microfluidic friction. This work will be useful to control the water inside the microfluidic …
