Graphene oxide (GO), which has many oxygen functional groups, is a promising candidate for use in moisture-responsive sensors and actuators due to the strong water-GO interaction and the ultrafast transport of water molecules within the stacked GO sheets. In the last 5 years, moisture-responsive actuators based on GO have shown distinct advantages over other stimuli-responsive materials and devices. Particularly, inspired by nature organisms, various moisture-enabled soft robots have been successfully developed via rational assembly of the GO-based actuators. Herein, the milestones in the development of moisture-responsive soft robots based on GO are summarized. In addition, the working mechanisms, design principles, current achievement, and prospects are also comprehensively reviewed. In particular, the GO-based soft robots are at the forefront of the advancement of automatable smart devices.
氧化石墨烯（GO）具有许多含氧官能团，由于其与水的强相互作用以及水分子在堆叠的 GO 片层内的超快传输，是用于响应湿度的传感器和致动器的有前途的候选材料。在过去的 5 年中，基于 GO 的响应湿度的致动器在性能上优于其他刺激响应材料和设备。特别是，受自然生物的启发，通过合理组装基于 GO 的致动器，已经成功开发了各种基于湿度的软体机器人。本文总结了基于 GO 的响应湿度的软体机器人的发展中的里程碑。此外，还全面回顾了其工作机制、设计原则、当前成就和前景。特别是，基于 GO 的软体机器人处于自动化智能设备发展的前沿。
