Abstract

Geckos have never failed to amaze the scientific realms with their fascinating innate characteristics. The species are adapted with a captivating pair of toepads that can reversibly attach to almost every surface, thus enabling them not only to climb vertically up but also to run across the ceilings. Moreover, the hierarchical fibrillar structure present in gecko’s feet provides an additional self-cleaning trait, especially under dry environments, which have gained immense importance in the field of soft robotics and smart adhesives. This perspective aims to provide a short reflection of the author on how the ‘self-cleaning’ traits work along with their exhibited mechanistic properties citing references of the recent advancements in the scope of self-cleaning gecko-inspired adhesives.

摘要

壁虎总是以其迷人的先天特征令科学领域惊叹不已。该物种适应了一对迷人的脚趾垫，几乎可以可逆地附着在每个表面上，从而使它们不仅可以垂直向上爬，而且可以穿过天花板。此外，壁虎脚中存在的分层原纤维结构提供了额外的自清洁特性，尤其是在干燥环境下，这在软机器人和智能粘合剂领域获得了巨大的重要性。这个观点旨在提供作者对“自清洁”特性如何与其展示的机械特性一起工作的简短反思，并引用了自清洁壁虎粘合剂范围内最新进展的参考资料。
