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 continuous glucose sensor configured and arranged for insertion into a host for and detecting glucose in the host, the sensor comprising:
- a first working electrode comprising a first resistance domain, wherein the first working electrode is configured to generate a first signal having a first noise component related to a noise-causing species;
- a second working electrode comprising a second resistance domain, wherein the second working electrode is configured to generate a second signal having a second noise component related to the noise-causing species;
- and
- a third resistance domain disposed continuously over the first resistance domain and the second resistance domain.
