  • Patent number: 9754704
    Abstract: A method of making a thin-film multi-layer micro-wire structure includes providing a substrate and a layer on the substrate with one or more micro-channels having a width less than or equal to 20 microns. A conductive material including silver nano-particles and having a percent ratio of silver that is greater than or equal to 40% by weight is located in the micro-channels and cured to form an electrically conductive micro-wire. The electrically conductive micro-wire has a width less than or equal to 20 microns and a depth less than or equal to 20 microns. Each micro-wire is electrolessly plated to form a plated layer located at least partially within each micro-channel between the micro-wire and the layer surface in electrical contact with the micro-wire. The plated layer has a thickness less than a thickness of the micro-wire so that the micro-wire and plated layer form the thin-film multi-layer micro-wire.

  • Patent number: 9591752
    Abstract: Conductive articles and devices have conductive micro-wires formed by curing a photocurable layer on a transparent flexible substrate that has a distortion temperature of less than 150° C.

Simultaneously, the rollers are pressed against the respective first portions and rolled along the respective support surfaces of the first and second stamps from the first portion to the second portion. The first and second curable layers are simultaneously cured to form cured imprinted layers on both sides of the substrate. The first and second stamps are removed.

    Abstract: A method of making a micro-channel structure and applying a curable ink to the micro-channel structure includes providing a substrate and depositing a single layer of a curable polymer on the substrate, the single curable layer having a layer thickness. One or more micro-channels adapted to receive curable ink are embossed into the single curable layer, the micro-channels having a micro-channel thickness that is in a range of two microns to ten microns less than the layer thickness. The single curable layer is cured to form a single cured layer so that deformations of the micro-channels or the surface of the single cured layer are reduced. Curable ink is coated over the surface and micro-channels of the single cured layer. The curable ink is removed from the surface of the single cured layer and the curable ink is cured.
