CONTACT:Liam Garvey
DESCRIPTION:The talk will review the state-of-the-art technologies in gas 
 sensors with emphasis on CMOS compatible gas-sensors.  The design and expe
 rimental results of a new generation of environmental gas and odour sensor
 s based on silicon-on-insulator (SOI) technology will be presented. Compar
 ed to current commercial solid-state gas sensors\, these new sensors offer
  ultra low power consumption (below 50 mW)\, a superior sensitivity to gas
 es\, full CMOS compatibility and low cost\; achieved through smart CMOS in
 tegration of the sensing device\, transducer and drive circuitry. Unlike e
 xisting commercial gas-sensors that employ platinum resistive heaters\, th
 ese new smart sensors have micro heaters embedded into a membrane made of 
 fully compatible CMOS layers.
