This study presents the development of gas sensors based on the PEDOT:PSS@ZnO hybrid active layer slot-die printing aqueous ink. Two different zinc oxide (ZnO) nanoparticles were studied to form the nanocomposites, as well as the use of glass and PET substrates to manufacture the devices. Despite the influence of the morphology of the active layer, all device variations studied here exhibited high response values for methanol gas at room temperature, in addition to presenting good repeatability, reversibility, and the possibility of technology transfer to flexible substrates. Furthermore, PEDOT:PSS@ZnO showed good selectivity to methanol compared to ethanol, ammonia, and CO
