First Claim
Patent Images
1. An electrochemical test strip comprising a multilayer construct including:
- a substrate layer having a top surface and a bottom surface,a metal conductor layer deposited onto the top surface of the substrate layer, anda protective layer deposited onto a top surface of the conductor layer, wherein the protective layer is a transparent conducting oxide;
wherein a pattern is formed from the metal conductor layer; and
wherein the protective layer has substantially continuous surfaces without any pattern formed therein.
