Graphene has attracted extensive attention because of its excellent electrical properties, outstanding thermal conductivity, high transparency, ultrathin thickness, and large specific area, and naturally, it has been used as a sensing material.
In ACS Applied Materials Interfaces “Simultaneous High Sensitivity Sensing of Temperature and Humidity with Graphene Woven Fabrics”, researchers now report a flexible temperature and humidity sensor (FTHS) from graphene woven fabrics (GWFs) prepared by chemical vapor deposition (CVD).
The sensor was prepared through an environmentally friendly layer-by-layer assembly process. Compared with the common graphene films produced by CVD, the GWF was composed of criss-crossed interlacing graphene micrometer ribbons and had rectangular holes, demonstrating ultra-sensitivity with a gauge factor of 500 to deformation within 2%.
