纳米布沙漠中的一些甲虫从它们的背上充满雾气的风中收集饮用水。我们在这里表明，这些大液滴形成凭借昆虫的凹凸不平的表面，其中包括交替的疏水性，蜡涂层和亲水性，非蜡质区域。这种集雾结构的设计可以在商业规模上廉价地复制，并且可以应用于例如集水帐篷和建筑物覆盖物，或者应用于水冷凝器和发动机。
Some beetles in the Namib Desert collect drinking water from fog-laden wind on their backs. We show here that these large droplets form by virtue of the insect's bumpy surface, which consists of alternating hydrophobic, wax-coated and hydrophilic, non-waxy regions. The design of this fog-collecting structure can be reproduced cheaply on a commercial scale and may find application in water-trapping tent and building coverings, for example, or in water condensers and engines.
