Abstract: Method for realising a sensor device (20) suitable for detecting the presence of chemical substances and comprising, as detection element, an active film (24) of metallic nanoparticles able to interact with the chemical substances to determine a variation of the global electric conductivity of the film (24). The method comprises the steps of preparing an ink comprising a solution of metallic nanoparticles, and depositing the obtained ink on a supporting substrate (26) by means of ink-jet printing so as to form the active film (24).
