Functionalized SnO2 Sensors on Flexible Substrate for Ammonia Detection at Low Temperature

Ce congrès est un événement digital: 4th international nanoFIS 2020 conference – 100% Digital at highest scientific level!; International audience; Ammonia detection at ambient with low-cost sensors is a challenge for various applications like breath analysis and agriculture. Such a challenge can be reached with functionalized SnO2 based gas sensors using silanization by 3-aminopropyltriethoxysilane (APTES) as an intermediate step before grafting with functional end group providing selectivity for the target gas. Moreover, operation at room temperature gives the opportunity to develop a sensor on a plastic substrate entirely manufactured by inkjet technology, by developing suitable inks, in particular to obtain SnO2 sensing element.
