摘要

这项工作提出了基于石墨烯的超灵敏表面声波(SAW)器件。由于在这一领域投入了大量的研究工作,石墨烯的创新解决方案已经准备好,以探索气体湿度传感应用。介绍了涂层传感器在c2h60和相对湿度条件下的实时检测测量。在目标分析物的低暴露下,蒸气化合物的吸附分别导致数千赫的频移。实验在室温条件下实现,反应速度快,恢复时间短。

Novel SAW gas sensor based on graphene
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.
