6.2.4 Influence of Flexible Substrate Materials on the Performance of Polymer Composite Gas Sensors

Thomas Kinkeldei, Christoph Zysset, Niko Münzenrieder & Gerhard Tröster
We report on the fabrication of gas sensors on different polymer substrates to evaluate the substrate material influence on the gas sensor performance. For this purpose, we developed a resistive type gas sensor out of a conductive polymer composite material on flexible polymer substrates (PI, PEN, PPS and PEI). We compared the sensors on polymer substrates to a similar one on a glass substrate as ground truth. The exposure to increasing levels of humidity showed...
