  • Publication number: 20240041366
    Abstract: A sensor, system, and method for detecting and correcting for an effect on an analyte indicator of an analyte sensor. The analyte indicator may have a first detectable property that varies in accordance with an analyte concentration and an effect on (e.g., degradation of) the analyte indicator. The analyte sensor may also include an interferent indicator having a second detectable property (e.g., absorption) that varies in accordance the effect on the analyte indicator. The analyte sensor may generate (i) an analyte measurement based on the first detectable property of the analyte indicator and (ii) an interferent measurement based on the second detectable property of the interferent indicator. The analyte sensor may be part of a system that also includes a transceiver. The transceiver may use the analyte and interferent measurements to calculate an analyte level.

  • Patent number: 11826143
    Abstract: A sensor (e.g., an optical sensor) that may be implanted within a living animal (e.g., a human) and may be used to measure an analyte (e.g., glucose or oxygen) in a medium (e.g., interstitial fluid, blood, or intraperitoneal fluid) within the animal. The sensor may include a sensor housing, an analyte indicator covering at least a portion of the sensor housing, and a multiple metal protective system including multiple metals incorporated in and/or in close proximity to a surface of the analyte indicator that reduce deterioration of the analyte indicator.

  • Publication number: 20230103609
    Abstract: A sensor, system, and method for detecting and correcting for changes to an analyte indicator of an analyte sensor. The analyte indicator may be configured to exhibit a first detectable property that varies in accordance with an analyte concentration and an extent to which the analyte indicator has degraded. The analyte sensor may also include a degradation indicator configured to exhibit a second detectable property that varies in accordance with an extent to which the degradation indicator has degraded. The analyte sensor may generate (i) an analyte measurement based on the first detectable property exhibited by the analyte indicator and (ii) a degradation measurement based on the second detectable property exhibited by the degradation indicator. The analyte sensor may be part of a system that also includes a transceiver. The transceiver may use the analyte and degradation measurements to calculate an analyte level.
