摘　　要：Decane is one of the volatile organic compounds （VOCs） in human breath. Successful detection of decane in human breath has vast prospects for early lung cancer diagnosis. In this paper, a novel detecting device based on a filter surface acoustic wave （SAW） gas sensor is presented. SAW sensors coated with a thin oxidized graphene film were used to detect decane in parts per million （ppm） concentrations. Control and signal detection circuits were designed using a vector network analyzer with a detection resolution of insertion loss down to 0.0001 dB. The results showed that the SAW sensor could respond quickly with great sensitivity when exposed to 0.2 ppm decane. This device shows tremendous potential in medical diagnosis and environmental assessment.Decane is one of the volatile organic compounds （VOCs） in human breath.
