在自然界中，各种界面上的机械联锁结构已经被观察了很长时间，并且它们的相互作用机制已经被深入研究。通过材料和结构工程，利用仿生联锁结构获得具有特定界面特性的理想功能，旨在现代电子产品中的实际应用。在本文中，这些生物启发的互锁被总结并根据其工程功能分为静态和可调节的类别。静态互锁增强界面强度，而可调节的互锁进一步促进可调和可逆的连接或刺激响应能力。各种仿生联锁结构与所需的功能提供的静态和可调联锁显示出巨大的潜力，在皮肤接口的电子产品，仿生粘合剂和可拉伸的电子皮肤的应用范围。然而，需要进一步探索和深入理解自然联锁的机制，以利用每个独特的联锁结构，为特定的应用场景。随着材料工程的发展，面向功能的互锁结构将在集成医疗电子产品中得到实际应用。
Mechanically interlocking structures at various interfaces in nature have been observed for a long time, and their underlying interacting mechanisms have been deeply investigated. Through material and structural engineering, bioinspired interlocking structures were exploited to gain desirable functionalities with specific interfacial properties, aiming for practical applications in modern electronics. Herein, these bioinspired interlocks are summarized and classified into static and regulable categories according to their engineered functionalities. Static interlocks enhance the interfacial strength, while regulable interlocks further facilitate tunable and reversible attachment or stimuli-responsive ability. Various biomimetic interlocking structures with desirable features offered by static and regulable interlocks show great potential in the application scope of skin-interfaced electronics, bioinspired adhesives, and stretchable electronic skins. Nevertheless, further exploration and thorough comprehension of mechanisms of natural interlocks are required to utilize each unique interlocking structure for a specific application scenario. With the advancement in materials engineering, functionality-oriented interlocking structures will be developed toward practical applications in integrated healthcare electronics.
