Amperometric sensor with an array of 8 working electrodes and 1 common reference electrode made by thick film technology with integrated connector

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