Abstract
An inertia microfluidic chip is designed to separate small particles suspended in a liquid. ANSYS fluent was further used to simulate the separation efficiently. Assuming the 3D printing resolution, the minimum printable feature size was assumed to be 850um. For results validation, the chip was made by a 3D printer and the separation was tested in the chip. Two particle sizes (50um and 5um) were used for testing. The particles were mixing first with ethanol and then diluted in water in order to create a suspension. A syringe pump then used to inject the flow into the chip. The results show good separation of particles with the selected design and in accordance with simulation results.
This results showing proof of principles of using day-today 3D printing tools for fabrication of microfluidics which can eliminates the needs for advanced manufacturing steps like photo-lithography for microfabrication of chips for particle separation. One of the main application of this technology is to enable separation of big dusts and air prolusions (which are in the same size category) for air quality monitoring in the GCC countries which is a big challenge. The next phase of this work is to integrate this chip with a sensing method (RF sensing) for continuous monitoring/detection.
