Novel SAW gas sensor based on graphene

Abstract : This work presents ultrasensitive Surface Acoustic Wave (SAW) devices based on graphene. Since, a great deal of research work has been invested in this field, graphene innovative solutions have been prepared in order to explore gas - moisture sensing applications. The real time detection measurement of the coated sensor under C2H6O and Relative Humidity (RH) is presented. The adsorption of vapor compounds leads to a frequency shift of several kHz, at low exposures of the target analytes, respectively. The experiments have realized at room temperature and rapid response and short recovery time were observed.
