Abstract:
1. A method of manufacturing electrochemical sensors, the method comprising steps of: forming a plurality of working electrodes on a first electrode region of a substrate; forming a plurality of counter electrodes on a second electrode region of the substrate; forming a plurality of indicator electrodes on one of the first and second electrode regions; disposing a spacer layer on one of the first and second electrode regions; removing a portion of the spacer layer to define sample chamber regions; folding the substrate with the spacer layer between the first electrode region and the second electrode region to form a layered structure; and separating a plurality of electrochemical sensors, each electrochemical sensor comprising at least one working electrode, at least one counter electrode, at least one indicator electrode, at least one sample chamber region, and first and second lateral extensions from the sensor body flanking the sample chamber region to indicate to a user where the openings for the sample chamber are provided.
