Abstract
A novel micro catalytic methane sensor array with four interchangeable sensor units operating at alternative "one-hot" mode was proposed and in-situ printed on a quartz micro hotplate. A quartz micro hotplate with high surface temperature gradient was utilized to decouple the temperature zones between a working units (450 °C) and rest of idle units (below 200 °C) due to quartz's low thermal conductivity. This "one-hot" design will enable the sensor array to endure 64 hours continuous working in 2% methane and maintained sensitivity above 12 mV/% CH4, which shows good prospect for long term coal mine applications.
