A sensor for use in a glucose measuring device, the sensor comprising: a plurality of electrodes, wherein the plurality of electrodes comprises a first electrode and a second electrode, wherein the first electrode comprises an electrochemically reactive surface;a non-conductive body located betwe
1. A sensor for use in a glucose measuring device, the sensor comprising: a plurality of electrodes, wherein the plurality of electrodes comprises a first electrode and a second electrode, wherein the first electrode comprises an electrochemically reactive surface;a non-conductive body located between the first electrode and the second electrode; anda multi-region membrane covering the plurality of electrodes, wherein the multi-region membrane comprises an immobilized enzyme domain comprising an enzyme in at least a portion thereof, wherein the immobilized enzyme domain covers and contacts the first electrode among the plurality of electrodes and does not cover and contact any other electrode of the plurality of electrodes. 2. The sensor of claim 1, wherein the multi-region membrane further comprises a resistance domain. 3. The sensor of claim 1, wherein the multi-region membrane comprises a silicone-containing copolymer. 4. The sensor of claim 3, wherein the multi-region membrane further comprises an acrylate polymer.
