Designing a humidity sensor with high performance to quick and accurate detect relative humidity (RH) is important in various applications. Consideration must be given to both the high response and the quick reversibility. Here, based on Quartz Crystal Microbalance (QCM) sensing platform, we utilized commercial graphene oxide as a sensing material, and added commercial carbon nanocoil to block the stacking of graphene oxide layers. The fabricated novel sensor possessed super high response (4618 Hz/97 % RH) and quick reversibility (2 s). This work not only expands the application of commercial carbon materials, but also achieves the development of high‐performance humidity sensor with commercial potential.

用于高性能湿度传感器的氧化石墨烯/碳纳米线圈复合材料

设计高性能的湿度传感器以快速准确地检测相对湿度（RH）在各种应用中很重要。必须同时考虑高响应性和快速可逆性。在此，我们基于石英晶体微天平（QCM）传感平台，利用商品化的氧化石墨烯作为传感材料，并添加了商品化的碳纳米线圈来阻止氧化石墨烯层的堆叠。所制造的新型传感器具有超高响应（4618 Hz / 97％RH）和快速可逆性（2 s）。这项工作不仅扩展了商业碳材料的应用，而且实现了具有商业潜力的高性能湿度传感器的开发。
