Fog harvest has emerged as a direct and efficient water harvesting technology to relieve the intense pressure of freshwater scarcity worldwide. With the vagaries of climate and increasing amount of energy consumption, high‐efficiency fog harvest devices focus on the fast water droplet capture and transportation are highly desired. In this study, a novel harp structure is developed using cross‐twisted copper filaments arranged in a spatial triangular pattern to enhance water droplet capture and transportation. Inspired by the natural differences in Laplace pressure observed in cactus and spider silks, this design accelerates the movement of water bridges. Besides, drawing on the fruit waxes on the surface of hogweed and blueberries, a paraffin wax coating is applied on the copper sheet frame to create a solid slip frame, improving the synergy between filament capture and frame transportation. The monolithic fog collector (MFC) thus achieves a significant increase in fog harvest efficiency and demonstrates excellent durability. Integration of the MFCs into a 3D high‐efficiency fog harvest system results in a harvest rate of 0.5027 g cm−2 min−1, showing promise for practical applications due to its durability, simplicity, and environmental friendliness.

3D 仿生集水系统可有效捕获和传输雾气


雾收集已成为一种直接有效的集水技术，可缓解全球淡水短缺的巨大压力。随着气候的变化和能源消耗量的增加，人们非常需要专注于快速水滴捕获和运输的高效雾收集装置。在这项研究中，开发了一种新型竖琴结构，使用以空间三角形图案排列的交叉扭曲铜丝来增强水滴的捕获和运输。受仙人掌和蜘蛛丝中观察到的拉普拉斯压力自然差异的启发，该设计加速了水桥的移动。此外，利用大猪草和蓝莓表面的果蜡，在铜片框架上涂上石蜡涂层，形成坚固的滑移框架，提高细丝捕获和框架运输之间的协同作用。因此，整体式集雾器 (MFC) 显着提高了集雾效率，并表现出出色的耐用性。将 MFC 集成到 3D 高效雾收集系统中，收集率达到 0.5027 g cm−2 min−1，由于其耐用性、简单性和环境友好性，显示出了实际应用的前景。
