Fog harvesting relies on a material's ability to quickly repel water droplets off its surface. Elastic slippery rough surfaces, consisting of PDMS lubricant-covered micropillars, exhibit passive actuation under fog harvesting conditions, resulting in more efficient water collection. In addition, a series of surface characterization tests were performed on these elastic slippery rough surfaces to gain a better understanding of how micropillar elasticity influences mobile Wenzel state droplets.
