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.
