Abstract: A method is provided to manufacture an electrochemical sensor that includes a strip with a receptacle formed therein, and a working electrode located in a wall of the receptacle. The method includes the steps of applying a working electrode layer onto a first insulating material, and applying a dielectric layer, formed by a first dielectric layer and a second dielectric layer, onto at least a part of the working electrode layer to form a laminate. A hole or well is created in the laminate, wherein the hole or well passes through the working electrode layer and a first surface of the laminate. The method further includes applying a pseudo reference electrode layer onto at least a part of the first surface of the laminate, and optionally attaching a base to a second surface of the laminate to produce a bonded article.
