Abstract

Microfluidics are being used in diagnostics, but their relative high cost has prevented their adoption in low resource settings so far. Here we present yarn based microfluidics with the potential for low cost manufacture. We describe methods to control the hydrophilicity of the yarn, its encapsulation, and how to make self-powered microfluidic circuits based on capillary force. Branched microfluidics were made by knotting two or more threads to one another. We discovered that knots are effective mixers, and that a different topology leads to different mixing results. We demonstrate a complex circuit using a mesh with hydrophilic, hydrophobic and selectively coated yarns and use it for transporting and routing different fluids along separate paths.
