3D-printed spider-web structures for highly efficient water collection

Environmentally Responsive Materials for Building Envelopes: A Review on Manufacturing and Biomimicry-Based Approaches

“…Some well-known examples of species that have inspired biomimetic approaches that could develop water harvest systems recently are: different species of cactus [ 57 , 75 , 76 , 77 , 78 , 79 ], spiders and spider silks [ 80 ], Triarrhena sacchariflora [ 81 ], pitcher plants [ 82 ], such as the Nepenthes alata [ 83 ], cicadas [ 74 ], and beetles [ 56 , 79 , 84 , 85 ]. According to Li et al [ 83 ], even if cactus and spider silk have been well-studied, their gradient surfaces can only move the harvested water droplets over a limited drop-sized distance, which leads to a slow speed and limited practical use.…”

Overview of the design of bionic fine hierarchical structures for fog collection

“…Although the structure of spider silk can readily cause directional transport, it is difficult to reproduce its spindle-knot structure via a straightforward method. 141…”

“…Although the structure of spider silk can readily cause directional transport, it is difficult to reproduce its spindle-knot structure via a straightforward method. 141 Inspired by cactus spines, the conical structure is the same to realize directional transport. Seven years ago, Zheng's group designed a type of artificial conical copper wire with HS, which was fabricated by controlled electrochemical corrosion methods with periodic current gradients inspired by spider silk and cactus spines.…”

Bionic Surfaces for Fog Collection: A Comprehensive Review of Natural Organisms and Bioinspired Strategies

“…In nature, certain insects and plants have evolved to utilize fog as an important source of freshwater, particularly in arid regions where rainfall is scarce . These organisms have undergone extended periods of evolution, developing specialized structures and chemicals that enable them to extract freshwater from fog. − Notable examples include the Namib Desert beetles, − spiders, − cactus, − etc. The mechanism of fog collection by these organisms has become a subject of considerable interest, leading to the development of various fog-collecting surfaces through different methods.…”
