摘要
Solid state gas sensor devices exhibit a high sensitivity in the ppm range and can be applied for the detection of noxious or explosive gases and vapours in air. Detection principles are outlined and examples for a spectroscopical characterization of gas-surface interactions are given. An improved specificity is attained by the use of sensor arrays and a computational evaluation, e.g. by a neural network. Recent realizations of such multisensor arrangements are discussed.
