Water Vapor Sensing by Carbon Nanoparticle “Skin”

An overlapping graphene nanoplatelet “skin” is fabricated on a single glass fiber surface, exhibiting multifunctional sensing capabilities for water vapor, relative humidity, liquid–solid phase transitions, and temperature. The “skin” sensor demonstrates capabilities for in-situ monitoring of human breathing frequency and liquid–solid phase transitions with a freezing point of traces of water on solid surfaces far below 0 °C.
