Abstract: Methods of passivating an adhesive via printing an ink onto a release liner, and adhesive articles or products made by the same are provided. An ink pattern is printed onto a release liner to form a pattern of features. The features are at least partially embedded in an adhesive layer such that when the release liner is peeled from the adhesive layer, the passivation features remain with the layer of adhesive to form selected areas having adjusted adhesive functionality. Articles including the passivated adhesive on a release liner are also disclosed.

Abstract: Electronic devices including a layer of polymeric material and solid semiconductor dies partially embedded in the layer are provided. The dies have first ends projecting away from the first major surface of the layer. The electronic devices can be formed by sinking the first ends of the dies into a major surface of a liner. A flowable polymeric material is filled into the space between the dies and solidified to form the layer of polymeric material. The first ends of the dies are exposed by delaminating the liner from the first ends of the dies. Electrical conductors are provided on the layer to connect the first ends of the dies.

Abstract: Processes of making an electrical jumper (120) for electrical devices are provided. A micro-replication stamp (300) is used to press a layer of curable material (124) on a circuit substrate (102) to make patterned features. A conductive liquid (230) is disposed into the patterned features to make electrically conductive traces (126) that pass over a circuitry (110) and connect electrical contacts (122A, 122B). In some cases, the stamp (300) has a standoff (310).

Abstract: A stretchable conductor includes a substrate with a first major surface, wherein the substrate is an elastomeric material. An elongate wire is on the first major surface of the substrate; the wire includes a first end and a second end, and further includes at least one arcuate region between the first end and the second end. At least one portion of the arcuate region of the wire in the region has a first surface area portion embedded in the surface of the substrate and a second surface area portion unembedded on the substrate and exposed in an amount sufficient to render at least an area of the substrate in the region electrically conductive. The unembedded second surface portion of the arcuate region may lie above or below a plane of the substrate. Composite articles including a stretchable conductor in durable electrical contact with a conductive fabric are also disclosed.

Abstract: The present disclosure relates to micro-optical assemblies containing at least one optical element adhered to a receptor substrate, e.g. a transparent receptor substrate, the receptor substrate contains at least one graphics layer. The micro-optical assemblies include both functional micro-optical structures that can alter, for example, incident light, and a graphic layer, which includes at least one graphic, e.g. a graphic design, which may include color, patterns, imagery, indicia and the like. The combination of the micro-optical elements with the graphic of the graphics layer can provide unique light altering assemblies that have graphic designs that may be functional, e.g. to display a message, and/or have aesthetic value. The micro-optical assemblies of the present disclosure are useful in a variety of applications which include, but are not limited to, display and graphics applications and architectural glass applications. The present disclosure also provides a method of making the micro-optical assemblies of the present disclosure.
