This paper describes a hydrogen sulfide (H2S) gas sensor using ionic liquid (IL). In this sensor, a reservoir for the IL was integrated above a surface acoustic wave (SAW) resonator. The IL serves as an absorber for H2S gas. Mass change due to this absorption is detected as a frequency-shift of the resonance. In this study, we fabricated and demonstrated the sensor using the LiNbO3 SAW resonator with the resonant frequency of 38 MHz. The integrated reservoir was filled by the IL 1-butyl-3methlimidazlium tetrafluoroborate ([BMIM]-[BF4]). As experimental results, we could observe the linear correlation between the amount of the frequency-shift and the exposure time of the sensor to the H2S gas.
