We report the design and scalable fabrication of a low-cost and low-power polyaniline-based (PANI) ammonia (NH3) gas sensor on polyimide (PI) substrates using additive manufacturing techniques. The silver interdigitated electrode (IDE) arrays and conducting polymer films are printed onto PI using a direct-write technology of aerosol-jet printing. Morphological characteristics are examined by scanning electron microscopy and energy-dispersive X-ray analysis which reveal homogeneously printed… 


Fabrication of an ammonia gas sensor using inkjet-printed polyaniline nanoparticles
An aqueous ammonia sensor based on an inkjet-printed polyaniline nanoparticle-modified electrode.
The combination of the environmentally inert, aqueous nanoparticle dispersion with the inkjet printing technique allowed the rapid fabrication of sensors based on polyaniline that was not easily achievable in the past due to the lack of processability of bulk forms of the conducting polymer.
Flexible room temperature ammonia sensor based on polyaniline
Ammonia/amine electronic gas sensors based on hybrid polyaniline–TiO2 nanocomposites. The effects of titania and the surface active doping acid
New ammonia and amine sensing materials based on hybrid polyaniline/titanium dioxide nanocomposites were synthesized by a one-pot chemical polymerization. Particular attention was paid to the
Polyaniline films deposited by anodic polymerization: Properties and applications to chemical sensing
Polyaniline conductive thin films have been used for the detection of a number of important gases and vapors: organic solvents, ammonia, oxygen, hydrogen sulfide, nitrogen and sulfur oxides. The
Flexible, all-organic ammonia sensor based on dodecylbenzene sulfonic acid-doped polyaniline films
Carbon Nanotube Sensors for Gas and Organic Vapor Detection
A gas sensor, fabricated by the simple casting of single-walled carbon nanotubes (SWNTs) on an interdigitated electrode (IDE), is presented for gas and organic vapor detection at room temperature.
