Abstract
A novel microwave-based gas sensor realized as a coupled-line section covered with a graphene oxide (GO) film as a gas-sensitive layer is proposed and verified. It is shown that the developed sensor’s reflection coefficient, measured at 2.4 GHz with the aid of a dedicated five-port reflectometer featuring decreased measurement uncertainty, can be used for estimating the gas concentration with a high level of accuracy. The developed microwave-based sensors were tested at room temperature under exposure to various volatile organic compounds: ethanol, acetone, methanol and isopropanol in the 0–200 ppm concentration range, with the highest response for acetone. Moreover, the simple circuitry of the proposed system together with its high performance enables its application in portable devices.
