Graphene oxide relative dielectric permittivity, both its real and imaginaryparts, have been measured under various humidity conditions at GHz. It isdemonstrated that the relative dielectric permittivity increases withincreasing humidity due to water uptake. This electrical property of grapheneoxide was used to create a battery-free wireless radio-frequency identification(RFID) humidity sensor by coating printed graphene antenna with the grapheneoxide layer. The resonance frequency as well as the backscattering phase ofsuch graphene oxide/graphene antenna become sensitive to the surroundinghumidity and can be detected by the RFID reader. This enables batterylesswireless monitoring of the local humidity with digital identification attachedto any location or item and paves the way for low-cost efficient sensors forInternet of Things applications.
