Development of a microfluidic gas generator from QQQAN efficient film-based microfabrication method

Abstract

We report the development of a microfluidic gas generator using polymer film-based microfabrication method. The method is time and cost efficient and capable of fabricating microfluidic devices with feature resolution lower than 100 μm. Complicated 3-dimentional devices can be fabricated by aligning and stacking multiple layers of patterned polymer (polystyrene, polycarbonate) films and double-sided tapes which are obtained from a digital craft-cutter. Integrated with functional features like Pt catalyst, the device can generate a variety of gas (O2, H2, etc) through controllable catalytic reaction.
