Abstract

Gas sensors are widely used in many industrial and home applications. There is therefore continued need to develop novel gas sensor substrates which provide good mechanical and electrical stability, and good flexibility in comparison with the conventional alumina and silicon-based materials. In this paper, we present the experimental results on flexible gas sensors based on the Kapton foil and alumina substrate covered by copper oxide as a gas-sensitive layer. These sensors exhibited good mechanical stability and gas-sensing characteristics. The Kapton-based CuO gas sensors were tested under exposure to acetone in the 0.05–1.25 ppm range (150 °C, 50%RH). The results confirmed that sensors deposited on the flexible substrate such as Kapton can be used in the exhaled breath analyzers dedicated to diabetes biomarker detection or other applications for which the elastic substrate is needed.

印刷在聚合物基板上的柔性气体传感器，用于低于ppm的丙酮检测

摘要

气体传感器广泛用于许多工业和家庭应用中。因此，继续需要开发与常规的氧化铝和硅基材料相比具有良好的机械和电稳定性以及良好的柔韧性的新型气体传感器基板。在本文中，我们介绍了基于Kapton箔和被氧化铜覆盖的氧化铝基底作为气体敏感层的柔性气体传感器的实验结果。这些传感器表现出良好的机械稳定性和气敏特性。基于Kapton的CuO气体传感器在暴露于0.05-1.25 ppm范围（150°C，50％RH）的丙酮中进行了测试。
