Abstract
In this work, the film of graphene oxide was deposited by drop-casting process for humidity sensor device. The structural property of graphene oxide film was performed by Raman spectroscopy. The humidity device was fabricated onto the indium tin oxide, as the transparent electrode. The device exhibited the adsorption and desorption behaviors of humidity in a range of 23-93 %RH. The complex impedance measurement was used to explain the mechanisms of the humidity device. The equivalent circuit model of the device was demonstrated.
