More Information
Summary:Functional ammonia, humidity and nitrogen dioxide sensors were fabricated by screen and gravure printing on flexible poly(ethylene terephthalate) (PET) substrates. Ammonia and humidity sensors were based on resistive principle (chemiresistors) while an electrochemical sensor was used for nitrogen dioxide detection - a semi-planar, three-electrode topology with polymer electrolyte containing organic ionic liquid was utilized. New type of polyaniline hydrochloride colloid was used as a sensitive layer for ammonia detection whereas a thin film of poly(3,4-ethylenedioxythiophene):poly(sodium 4-styrenesulfonate) (PEDOT:PSS) was used for the humidity sensor. All sensors were completely prepared by printing technologies which enables future compatibility with R2R fabrication process intended for mass production of low cost and all-organic flexible gas sensors.
