Claim Text:
1. A method of making a transparent micro-wire device including a cured ink located in a micro-channel structure, comprising: a) providing a substrate having a transparency of greater than 50%, wherein the substrate has a first side opposite and substantially parallel to a second side; b) depositing a first single layer of a curable polymer on the first side of the substrate, the first single curable layer having a surface and a first layer thickness; c) embossing one or more first micro-channels into the first single curable layer, the first micro-channels having a first micro-channel thickness that is in a range of two microns to ten microns less than the layer thickness, and curing the first single curable layer to form a first single cured layer having a thickness that is in a range of about four microns to about twelve microns so that deformations of the first micro-channels or the surface of the first single cured layer are reduced; d) coating a curable ink over the surface and first micro-channels of the first single cured layer; e) removing the curable ink from the surface of the first single cured layer; f) curing the curable ink in the first micro-channels; g) depositing a second single layer of the curable polymer on the second side of the substrate, the second single curable layer having a surface and a second layer thickness; h) embossing one or more second micro-channels into the second single curable layer, the second micro-channels having a second micro-channel thickness that is in a range of two microns to ten microns less than the second single curable layer thickness, and curing the second single curable layer to form a second single cured layer so that deformations of the second micro-channels or the surface of the second single cured layer are reduced; i) coating the curable ink over the surface and second micro-channels of the second single cured layer; j) removing the curable ink from the surface of the second single cured layer; and k) curing the curable ink in the second micro-channels to provide a transparent micro-wire device.
