  This work focuses on the application related to the detection of low moisture
and environmental pollutants. A novel gas sensor with inkjet printed Double
Walled Carbon Nano Tubes (DWNTs) on a Love wave sensor platform was developed
for Volatile Organic Compounds (VOCs) and humidity detection application. The
experiments were conducted in real-time at ambient conditions. Results
demonstrate the adsorption of vapor compounds on DWNTs sensitive material and
leads for example to frequency shifts of 1.97 kHz and 2.93 kHz with 120 ppm of
ethanol vapor and 6.22 % RH, respectively.
