This paper reports on a low-power-consumption carbon dioxide (CO2) gas sensor based on an ionic gel. Ionic gel is a mixture of ionic liquid and polymer. We employed 1-ethyl-3-methyl-imidazolium tetrafuloroborate ([EMIM][BF4]) as ionic liquid and polyvinylidene fluoridecohexafluoro propylene (PVDF-HFP) as polymer. The [EMIM][BF4] selectively absorbs CO2 gas. Our proposal sensor consisted of an ionic gel and two Pt electrodes patterned under the ionic gel. The CO2 gas concentration can be… CONTINUE READING
