Abstract
Disclosed herein are systems and methods for a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes first and second working electrodes to measure additional analyte or non-analyte related signal. Such measurements may provide a background and/or sensitivity measurement(s) for use in processing sensor data and may be used to trigger events such as digital filtering of data or suspending display of data.
Claims20
A sensor for measuring an analyte in a host, the sensor comprising:
- a first working electrode disposed beneath an active enzymatic portion of a first membrane;
- and
- a second working electrode disposed beneath an inactive-enzymatic portion of a second membrane, wherein the inactive enzymatic portion comprises at least one of a deactivated enzyme or an inactive enzyme, wherein the first working electrode and the second working electrode are coaxial.
A sensor for measuring an analyte in a host, the sensor comprising:
- a first working electrode disposed beneath an active enzymatic portion of a membrane system;
- a second working electrode disposed beneath an inactive-enzymatic or non-enzymatic portion of the membrane system;
- and
- an insulator located between the first working electrode and the second working electrode, wherein the first working electrode and the second working electrode are coaxial.
