Inkjet printed colorimetric ammonia sensor on plastic foil ...

The gas sensitive layer was inkjet printed on a plastic foil used as an optical waveguide. The planar configuration of the sensor makes it compatible with large scale fabrication techniques, such as roll-to-roll processes. Its power consumption and noise level were measured. The sensor exhibited a good sensitivity to ammonia with a theoretical limit of detection of 104 ppb in a constant ...
