Inkjet – printed graphene oxide thin layers on Love wave devices for humidity and vapor Detection

Abstract : We report inkjet printing as an alternative deposition method for low-cost gas or humidity sensors based on graphene oxide (GO)-coated Love wave devices. Our inkjet printing method paves the way toward massive, large-area industrial production of multi-layered GO chemical sensing films for volatile organic compounds and relative humidity (RH) detection applications. The adsorption of vapor compounds on GO led to the sensitivities of 30 Hz/ppm, 24 Hz/ppm, and 2.4 kHz/1% of ethanol (C2H6O), toluene (C7H8), and RH, respectively. Electrical, gaseous, and RH characterization analyses showed that this GO-based inkjet printing method is one of the most promising features for inexpensive and high-speed patterning devices for high demanding gas trace or RH sensing applications.
