Engineering approaches for the improvement of conductometric gas sensor parameters

Engineering approaches designed to improve the parameters of conductometric gas sensors, are considered in this short survey. In particular, in the first part of the paper we analyze the engineering approaches used for the improvement of sensor sensitivity and selectivity. Analysis has shown that engineering approaches in a number of cases can eliminate some intrinsic disadvantages of conductometric gas sensors, can give significant improvement of gas sensors performances and expand their application in various fields.
