Abstract
An inventive electrochemical sensor has a substrate with proximal and distal regions. The proximal region has at least one contact element configured to communicate with a measurement device. A working electrode is located in the distal region of the substrate and includes a conductive trace. A plurality of enzyme fields are provided, each enzyme field having an enzyme configured for providing a reaction with an analyte. The enzyme fields are spaced apart and each enzyme field is at least partially located on the conductive trace. The conductive trace may be provided in the form of a grid. The enzyme fields can be formed such that they extend beyond one or both edges of the trace or such that they cover only a portion of the full width of the trace. Manufacturing tolerances can be improved.
