A photonic gel sensor changes its color by external stimulus without detector and it is changed by Bragg's law. In this study, we investigate aldehyde responsive photonic gel sensor that can be used for breath analyzer. Most of hydrogel sensors are used in an aqueous environment. However, by using F-containing ionic liquid instead of water, the sensor exhibited low volatility and thermal stability, and changed the color by aldehyde and alcohol vapor. The sensor responses were rigorously investigated with repeated changes in N2/acetaldehyde mixture in various composition. The results demonstrate that the higher the flow rate of vapor and the composition acetaldehyde, the higher the responsibility |
