Abstract
This work reports on a passive compact flow regulator designed to maintain a steady flow during breath diagnostics using a flow regulation principle where a cantilever is directed towards the direction of the flow. A theoretical model has been developed describing the flow behavior and a prototype has been fabricated for proof of concept. The prototype uses a single integrated 300 μm thick 3D-printed plastic cantilever to control comparatively large air flows in the 50 ml/s regime suitable for asthma diagnostics.
