Multi-layer micro-wire structure

摘要

A multi-layer micro-wire structure resistant to cracking including a substrate having a surface, one or more micro-channels formed in the substrate, an electrically conductive first material composition forming a first layer located in each micro-channel, and an electrically conductive second material composition having a greater tensile ductility than the first material composition forming a second layer located in each micro-channel, the first material composition and the second material composition in electrical contact to form an electrically conductive multi-layer micro-wire in each micro-channel, whereby the multi-layer micro-wire is resistant to cracking.

1. A multi-layer micro-wire structure resistant to cracking, comprising:
a substrate having a surface; one or more micro-channels formed in the substrate; an electrically conductive first material composition forming a first layer located in each micro-channel; and an electrically conductive second material composition having a greater tensile ductility than the first material composition forming a second layer located in each micro-channel, the first material composition and the second material composition in electrical contact to form an electrically conductive multi-layer micro-wire in each micro-channel, wherein the first material composition is susceptible to cracking when the multi-layer micro-wire structure is flexed such that gaps are formed in the first material composition, and wherein the second material composition forms an electrical connection that bridges the formed gaps, whereby the multi-layer micro-wire is resistant to cracking.
