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. Self-healing graphene oxide (GO) functional architectures including 3D compressible foams, 2D flexible films, and 1D wearable fibers are demonstrated. These GO assemblies exhibit excellent and fast self-healing ability with moisture assistance. Apart from the construction of graphene macroblocks, this promising healing ability has been incorporated into GO smart actuators and sensors.
