Narrow amperometric single working electrode sensor made by thick film technology

The sensor is formed on a corundum ceramic base. On to this surface the working electrode is applied. The working electrode is made of variety of materials. At the end of the sensor there is a contact which 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.
