Abstract
A gas sensor includes a substrate preferably made of beryllium oxide which is both an electrical insulator and thermal conductor, the substrate having thereon at least one heating element for the substrate, at lease one gas-sensitive active material deposited on the substrate and a set of at least two space electrodes in contact with the active material. The thermal conductivity of the substrate as arranged together with the heating element cooperate and assists to ensure that the substrate achieves a desired thermal gradient while the sensor establishes a near-uniform temperature throughout substantially the entire sensor, thus enabling the operating temperature of the active material to be maintained substantially constant throughout its entire volume.
