Abstract
The present invention provides an inventive biosensor that includes multiple regions in which the electrical pattern is formed from different electrically conductive materials. The present invention also provides an inventive method for mass producing biosensors as just described. In one embodiment of this method, first and second different electrically conductive materials are deposited side by side on a portion of an electrically insulating base material, and a plurality of electrical patterns is formed on the portion of the base material. Each electrical pattern includes a first region formed from the first electrically conductive material electrically connected to a second region formed from the second electrically conductive material. The electrically conductive materials can be deposited as layers on the base material and portions of the layers can be removed to form the electrical patterns, or, the electrical patterns can be formed by transferring the conductive material in the shape of the electrical pattern directly to the base material, such as by a laser direct transfer technique.
