  • Patent number: 11630075
    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, a conductive layer deposited on the substrate, and a resistive material layer deposited on the conductive layer. 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 25 to less than 95 weight percent, the weight percent of nickel in the conductive layer is at least 4 weight percent, the weight percent of chromium in the conductive layer is at least 10 weight percent, the weight percent of iron in the conductive layer at least 2 weight percent, and such that the conductive layer comprises 0 to 20 weight percent molybdenum.
    Type: Grant
