  • Physical vapor deposited biosensor components
    Patent number: 11835481
    Abstract: A biosensor component is provided that provides enhanced characteristics for use in biosensors, such as blood glucose sensors. The biosensor component comprises a substrate and a conductive layer coated on the substrate. The conductive layer includes nickel, chromium, and iron, such that a combined weight percent of the nickel and chromium in the conductive layer is in the range of 80 to less than 95 weight percent, and the weight percent of iron in the conductive layer is greater than 5 weight percent and less than 12 weight percent.
    Type: Grant
    Filed: June 1, 2017
    Date of Patent: December 5, 2023
    Assignee: Eastman Chemical Company
    Inventors: Spencer Erich Hochstetler, Senthil Nathan Sambandam, Dennis Lee Ashford, II
  • Physical vapor deposited biosensor components
    Patent number: 11609205
    Abstract: A biosensor component that provides enhanced characteristics for use in biosensors, such as blood glucose sensors. The biosensor component comprises a substrate, and a composite layer deposited on the substrate. The composite layer includes a conductive metal component and a resistive material component, where the conductive metal component comprises one or more non-noble metals, and where the resistive material component in the composite layer is present in an amount greater than 20 atomic percent.
    Type: Grant
