Kirigami fog nets: how strips improve water collection

P. Bintein, A. Cornu, et al.

This innovative research conducted by Pierre-Brice Bintein, Axel Cornu, Floriane Weyer, Nicolas De Coster, Nicolas Vandewalle, and Denis Terwagne explores the potential of kirigami-designed fog nets in harvesting water more efficiently than traditional methods, addressing the urgent issue of water scarcity driven by climate change.... show more
Abstract
As scarcity of water is expected to intensify with global warming, unconventional water sources such as advective fogs may become essential. In numerous arid regions, nets are used to harvest such water droplets. However, many current fog nets are either not durable or expensive, and have poor performances for short time or low intensity fog events. With a dedicated test bench, we show here that a low-cost net with kirigami design offers a higher and faster fog collecting ability than the usual fibers nets. This kirigami fog net consists of a continuous network of strips where water quickly forms a stable film, accounting for its superior capture efficiency. We rationalize this mechanism with a simplified structure composed of disconnected strips whose optimization paves the way to the shaping of original fog nets such as the kirigami one.
