Abstract(summary):

There is a need for low-cost mass-production circuits on various substrates, possibly performing some simple functions as switches, antennas, displays, and sensors. Also in the field of gas sensors widely used in several applications there is a need for such novel fabrication technologies and materials. In this paper, we present three gas sensor structures fabricated using novel printing techniques. Inkjet and gravure printing techniques were used for fabrication of resistive WO3 nanoparticle gas sensors for detection of NO, and inkjet printing was utilized for fabrication of solid electrolyte (mixture of H3PW12O40 and PVC) in a nanostructured Metal-Electrolyte-Insulator-Semiconductor (MEIS) transistor for detection of H-2. The sensor structures were found to be sensitive for detection of NO below 10 ppm, and H-2 below 100 ppm concentrations in synthetic air, respectively. (C) 2011 Published by Elsevier Ltd.
