Abstract: A gas sensing device is manufactured with three dimensionally connected metal oxide foam structure of large surface area and elongated channel pores within the three-dimensional porous structure for gas sensing applications, thereby increasing the surface area of the sensing layer and expediting sensitivity and sensor response. A gas sensor device includes the fabricated metal-oxide-foam sensing material attached via silver paste to platinum electrodes and ruthenium heater that are printed on low temperature co-fired ceramic substrate. This device will provide improved gas sensing performance with improved sensitivity and response time. Gas sensors including the metal oxide foam sensing material exhibit higher sensitivity to toxic gases such as ethanol and carbon monoxide due to the large surface area achieved from the porous three-dimensional structure providing increased chemical reaction sites and the larger porous channels allowing gases to easily pass, shortening the gas diffusion reaction path.
