Date Jan. 29, 1987.A description is given of sensors in in the form of field effect transistors and capacitors which are suitable for qualitatively and quantitatively determining species to be analyzed, for example molecules or ions, in liquid or gaseous media. A special field of application is the selective determination of the presence and concentration of gases. The sensors are defined in that they have a sensitive layer consisting of a heteropolysiloxane.
