Research Abstract |
Different types of gas sensors (semiconductor-type, solid-electrolyte-type, photoluminescence-type and adsorption/combustion-type) have been developed by various techniques (screen-printing, dip-coating with modified a sol-gel technique and radio-frequency magnetron sputtering) employing a self-assembly of surfactants as a mesopore template and/or polymethylmethacrylate microspheres as a macropore template. The strict control of the gas-reactivity and -diffusivity of gas sensing materials by their microstructural and/or compositional optimization effectively improved their gas sensitivity and response and recovery speeds.
