Abstract
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 H2. The sensor structures were found to be sensitive for detection of NO below 10 ppm, and H2 below 100 ppm concentrations in synthetic air, respectively.
