Patent ID: 8308922

Claim:
A biosensor operating on an electrochemical detection principle, comprising: a transducer array, containing a flexible metal/isolator composite composed of a metal layer having a top surface and a bottom surface that separates a first isolator layer from a second isolator layer, with a permanent connection between the top surface of the metal layer and the bottom surface of the first isolator layer and a permanent connection between the bottom surface of the metal layer and the top surface of the second isolator layer and a permanent connection between the bottom surface of the metal layer and the top surface of the second isolator layer, the metal layer structured such that individual measurement electrodes and at least one reference electrode are electrically isolated from one another are formed, said bottom surface of the first isolator layer, directly contacting said top surface of the metal layer, the first isolator layer having open spaces formed therein such that the top surface of the metal layer has exposed areas as sensor surfaces in the isolator layer; said top surface of the second isolator layer directly contacting said bottom surface of the metal layer, the second isolator layer exposing portions of said metal layer such that they can each be electrically contacted with discrete electrodes.
