Abstract: The invention relates to a reference electrode for chemical sensors based on ion-selective field-effect transistors (CHEMFETs) in an electrolyte/insulator/semiconductor (EIS) system. The reference electrode consists essentially of an insulator/semiconductor substrate coated with polyglutamate or of a phthalocyaninato-polysiloxane polymer film which is coated with polyglutamate and mounted on an insulator/semiconductor substrate.

Abstract: The invention relates to a miniaturisable, capacitively measuring chemical sensor system on a semiconductor basis, comprising a sensor and a reference element which are to be contacted with the electrolyte to be measured, the reference element being connected in series with the sensor, the reference element comprising a highly doped semiconductor substrate or metal/semiconductor substrate which is coated with a membrane, and the sensor comprising an insulator/semiconductor substrate which is coated with a sensitive membrane, and the sensitive membrane of the sensor being more sensitive than that of the reference element. Sensor and reference element of said sensor system can either be applied to the same chip or consist of individual components which can readily be interchanged.
