  • Patent number: 11963761
    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 one or more compounds having metal chelating moieties that reduce degradation of the analyte indicator.

  • Patent number: 10392538
    Abstract: A pressure sensitive adhesive composition is described comprising at least one low Tg (meth)acrylic polymer, and at least one silsesquioxane polymer crosslinker comprising a plurality of ethylenically unsaturated groups. The low Tg (meth)acrylic polymer typically has a Tg no greater than 10° C. In some embodiments, the low Tg (meth)acrylic polymer comprises at least 50, 55, 60, 65, or 70 wt-% of polymerized units derived from low Tg ethylenically unsaturated monomer(s). The low Tg ethylenically unsaturated monomer(s) is typically an alkyl (meth)acrylate comprising 4 to 20 carbon atoms. Also described are pressure sensitive adhesive articles and methods of preparing such articles.
