摘要
Presently described are articles such as antennas, EMI shields, and touch screen sensors as well as patterned substrates having overlaid micropatterns with low visibility. Also described are methods of determining the visibility of a patterned substrate. In one embodiment, a patterned substrate is described comprising a visible light transparent substrate; and at least two overlaid electrically conductive mesh micropatterns, wherein each mesh has a repeating cell geometry and the combination of overlaid micropatterns has a spatial constrast threshold at a distance of 30000 units of greater than - 35 decibels.
