Self‐healing materials are capable of spontaneously repairing themselves at damaging sites without additional adhesives. They are important functional materials with wide applications in actuators, shape memorizing materials, smart coatings, and medical treatments, etc. Herein, this study reports the self‐healing of graphene oxide (GO) functional architectures and devices with the assistance of moisture. These GO architectures can completely restore their mechanical‐performance (e.g., compressibility, flexibility, and strength) after healing their broken sites using a little amount of water moisture. On the basis of this effective moisture‐triggered self‐healing process, this study develops GO smart actuators (e.g., bendable actuator, biomimetic walker, rotatable fiber motor) and sensors with self‐healing ability. This work provides a new pathway for the development of self‐healing materials for their applications in multidimensional spaces and functional devices.

水分触发的基于自修复氧化石墨烯的功能架构

自修复材料能够在损坏部位自发修复，而无需使用其他粘合剂。它们是重要的功能材料，在执行器，形状记忆材料，智能涂料和医疗等领域具有广泛的应用。在此，本研究报告了在水分的帮助下氧化石墨烯（GO）功能结构和设备的自修复。这些GO体系结构在使用少量水湿气修复破裂的部位后，可以完全恢复其机械性能（例如，可压缩性，柔韧性和强度）。在此有效的水分触发自修复过程的基础上，本研究开发了具有自修复能力的GO智能执行器（例如，可弯曲执行器，仿生步行器，可旋转光纤电机）和传感器。
