| Summary: | In this article, we present the results of GO as a primary material of the humidity sensor and the electro-physical characteristics of this sensitive element. The sensitive humidity sensor created using the GO membrane was obtained via vacuum filtration. Initial material GO was synthesized by the modified Hummers method and characterized by Raman spectroscopy, XRD analysis and SEM. The stability of the electrical resistance, also the rate of recovery and response of a humidity sensor element based on GO was studied as a function of the relative humidity level. The GO sensor was demonstrated to function properly in a wide range of humidity over an extended 10 hour period at room temperature. The deviation of the electrical resistance readings of the device during the experiment did not exceed 2 %. |
