The sensor is formed on a corundum ceramic base. On to this surface the working, the reference and two auxiliary electrodes are applied. The electrodes can be made from variety of materials (see below). At the end of the sensor there is a contacting field. It is connected with the active part by the silver conducting paths which are covered by a dielectric protection layer. A bio-chemically active substance can be immobilised on the working electrode of the sensor.
