Abstract

An analyte sensor system including a substrate, a first electrode disposed on a first surface of the substrate, a second electrode disposed on a second surface of the substrate, a third electrode provided in electrical contact with at least one of the first or second electrodes, where at least a portion of the first electrode and the second electrode are subcutaneously positioned in a patient, and where the third electrode is substantially entirely positioned external to the patient, and corresponding methods are provided.

Claims

1. A method of providing an analyte sensor, comprising the steps of:

providing a substrate;

disposing a first electrode on a first surface of the substrate;

disposing a second electrode on a second surface of the substrate; and

positioning a third electrode in electrical contact with the first and second electrodes, where the third electrode is substantially entirely external to the patient.
