Biosensor test member and method for making the same

摘要

A biological test member, and method of making the same, is disclosed with the member including a substrate. The test member has usefulness, for example, in testing a person's blood glucose level. A first layer and a second layer of conductive metal are printed or otherwise applied on the substrate in an electrode pattern. The metal or metals are cured or sintered at a low, non-damaging temperature, such as by applying one or more pulses of a high-energy broad spectrum light. A layer of reagent may be provided on said second metal layer.

主权项

1. A biosensor test member, comprising:
an electrically conductive first layer comprising a first metal in an electrode pattern on a substrate such that said first layer has at least two electrode layer portions that are spaced from each other on said substrate; and an electrically conductive second layer comprising a second metal and located on and substantially coinciding with said electrically conductive first layer such that said electrically conductive second layer has at least two second layer electrodes portions that are spaced from each other on said substrate, wherein said second metal is different from said first metal, and said first metal and said second metal being at least partially sintered together, and wherein said first metal and said second metal each are in a cured ink carrier of the respective first layer and second layer.
