Chemoresitive gas sensors based on multiple nanowires (M-NWs) randomly grown and electrically inter-connected on the top of interdigitated electrodes (IDEs) and arrays of single nanowires connected between faced nanoelectrodes (A-S-NWs) are developed in this work. These systems, consisting of gas sensitive tungsten oxide nanowires (NWs), are tested to NO2, and their performance regarding the response magnitude, sensitivity and response rate are evaluated here.

Highly Sensitive Detection

Here we report on fabrication of integrated-optical sensors for relative humidity and ammonia detection based on natural polysaccharide chitosan. The sensing properties of the fabricated sensor to gaseous ammonia are presented. The sensor exhibits a linear response in the range of 1-300 ppm with the response time less than 1 second. It has been shown that 1 μm-thick chitosan-based waveguide film allows highly sensitive detection of RH level.
