Abstract

Chemical concentrations such as gas partial pressures may be determined by making use of the class of recently developed solids with fast ion transport. For the detection of many species it is required to modify the surface. Chemical concentrations are directly converted into electrical signals which may be readily further processed for actors or simply for display. The sensors may be based on potentiometric and amperometric principles depending on the specific type of application. Appropriately selected materials allow to eliminate problems of interference by other chemical species. The development of suitable materials has to include also the reference electrodes and housing.
