We report on the fabrication process of a sensing device obtained by ink‐jet printing of polyaniline suspension on alumina substrates. We optimized the inkjet parameters (amplitude and duration of jetting impulse, jetting frequency, substrate velocity) to obtain thin polyaniline lines as sensitive layers and we analyzed the morphology of PANI lines on substrate. Device response towards ammonia are also discussed and compared with reference device obtained by spin‐coating.
