Research on Selective Thick Film CO Gas Sensors and Their Characters |
| |
| Abstract: | Selective thick film CO gas sensors were made. The characters of gas sensitivity and thick film heater were investigated. A better identity of the sensors was obtained by controlling suitable conditions. At low temperatures, high sensitivity and selectivity were obtained by adding proper dopants. The thick film heater has a better stability by using a protecting layer. |
