Space-filling open microfluidics for droplet collection: Generalized design of fractal hyperbranched channels

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We have previously designed hyperbranching open microfluidic channels that collect aqueous droplets sprayed on the surface, by means of directional droplet transport by Laplace pressure imbalance and hierarchical fusion of droplets. The channels were made of a fractal branching, space-filling tree that densely fills a triangular area, and can accumulate liquid at the central focal point. In this study, the patterns of space-filling open microfluidic channels are generalized so that the pattern can cover any convex polygon with an arbitrary focal point. The distributions of liquid at the equilibrium for different space-filling patterns are experimentally investigated.
