Rapid detection of volatile organic compounds (VOCs) from skin ducts as biomarkers leads to early diagnosis of disease in human beings [1]. The skin emits gas molecules such as acetone, NH3, H2S, and VOCs which are considered primary and key biomarker gases in the detection and diagnosis of numerous diseases like diabetes, asthma, renal disease, halitosis, and lung cancer [2]. Recently, graphene has attracted much attention as a promising material in the detection of toxic gases due to its excellent physical and chemical properties such as large young modulus, elasticity, single-atom thickness, and large surface area. These properties drive graphene as an ideal material for the Surface acoustic wave sensor (SAW) [3]. Herein, we report the experimental and simulation of a suspended chemical vapour deposition (CVD) grown graphene SAW (SG-SAW) sensor operating with love mode to detect acetone gas in a real time atmosphere.
