Biomimetic fog-collecting meshes

Jonathan Chan, New Zealand 16-18

Fog collection is a method of atmospheric water collection used in less economically developed areas of the world located in high-altitude and arid environments. It involves the collision of fog droplets with a mesh, which then coalesce to form larger droplets that drain away and are collected. Certain organisms have directional water-collecting properties that would facilitate this process, such as the cribellate spider web and the cactus spine. Thus, this project aims to incorporate such biomimetic properties into reproducible, industrially applicable 3D-printed fog-collecting meshes and to investigate the fog-collecting efficiency of such meshes.
