Abstract:
1. A continuous glucose sensor configured for insertion into a host's tissue, the sensor comprising: a first working electrode comprising a first electroactive surface disposed beneath an active enzymatic portion of a sensor membrane, wherein the active enzymatic portion of the sensor membrane is configured to produce H a second working electrode comprising a second electroactive surface disposed beneath an inactive-enzymatic or a non-enzymatic portion of the sensor membrane, wherein the second working electrode is configured to generate a second signal having a second noise component related to the noise-causing species, wherein the first electroactive surface and the second electroactive surface are each dimensioned to integrate at least one signal generated by a plurality of local point sources that produce the noise-causing species, such that the first noise component and the second noise component are substantially equivalent; wherein each of the first electroactive surface and the second electroactive surface are configured and arranged to integrate noise detected about a circumference of the sensor.
