Velcro, the most typical hook‐loop interlocker, often suffers from undesirable deformation, breaking, and noise because of the structure of the hook. Inspired by the arrester system of dragonfly, a new mechanical interlocker with a nylon pestle instead of the traditional hook is developed. The pestle‐loop mechanical interlocker shows a tunable peeling force from 0.4 ± 0.14 to 6.5 ± 0.72 N and the shear adhesion force of pestle‐loop mechanical interlocker is about twice as much as that of velcro. The pestle tape can be separated and fastened with the loop tape up to 30 000 cycles while keeping the original adhesive force and the pestle structure. In comparison, only after 4000 cycles most hooks of the commercial velcro are deformed and even broken, completely losing their adhesive function and their hook structure. These experimental results are further supported by finite element simulitions—the base of pestle mainly bears the separation‐caused strain while the middle of hook does. Notably, the sound volume during the separation of pestle‐loop mechanical interlocker is merely 49 ± 7.4 dB, much lower than 70 ± 3.5 dB produced by the velcro.

仿生超耐用杵环机械联锁器，具有可调剥离力、强剪切粘合力和低噪音

魔术贴是最典型的魔术贴，由于其钩子​​的结构，经常会出现变形、断裂和噪音等问题。受蜻蜓制动系统的启发，开发了一种新型机械联锁器，用尼龙杵代替传统的钩子。杵环机械联锁装置的剥离力可调，范围为 0.4 ± 0.14 至 6.5 ± 0.72 N，并且杵环机械联锁装置的剪切粘附力约为尼龙搭扣的两倍。研杵胶带可与环形胶带分离并紧固多达 30 000 次，同时保持原有的粘合力和研杵结构。相比之下，大多数市售魔术贴的钩子仅在4000次循环后就变形甚至断裂，完全失去了粘合功能和钩子结构。这些实验结果得到了有限元模拟的进一步支持——杵的底部主要承受分离引起的应变，而钩的中部则承受。值得注意的是，杵环机械联锁器分离时的音量仅为49±7.4dB，远低于魔术贴产生的70±3.5dB。
