在这里，报告了一种基于石墨烯的湿度传感器的简易制造方法，用于智能器件设计。聚焦太阳光光还原氧化石墨烯(GO)有助于去除GO片上的大部分含氧基团，这不仅恢复了它们的导电性，还导致形成了高度多孔的纳米结构，使得通过非常简单的技术制造多功能湿敏智能设备，如湿度控制器、湿度检测器机器人，甚至是一种新型的电子口琴。作为一种简单、不含化学物质的方法，聚光光还原GO为智能设备的发展提供了一条制造多功能传感器件的途径。
Here, a facile fabrication of graphene-based humidity sensors is reported for smart device design. Focused sunlight photoreduction of graphene oxide (GO) helps to remove most of the oxygen-containing groups on GO sheets, which not only recovers their conductivity but also leads to the formation of a highly porous nanostructure, enabling the manufacture of versatile humidity-sensing smart devices, such as moisture controllers, humidity detector robots, and even a novel electronic harmonica, through a very simple technique. As an uncomplicated and chemical-free method, focused sunlight photoreduction of GO provides an avenue to produce versatile sensing devices for the development of smart devices.
