Abstract: A method of applying a pattern to a nonplanar surface. A stamp has a major surface with pattern elements having a lateral dimension of greater than 0 and less than about 5 microns. The major surface of the stamp has a functionalizing molecule with a functional group selected to chemically bind to the nonplanar surface. The stamp is positioned to initiate rolling contact with the nonplanar surface, and contacts the nonplanar surface to form a self-assembled monolayer (SAM) of the functionalizing material thereon and impart the arrangement of pattern elements thereto. The major surface of the stamp is translated with respect to the nonplanar surface such that: a contact pressure is controlled at an interface between the stamping surfaces and the nonplanar surface, and a contact force at the interface is allowed to vary while the stamping surfaces and the nonplanar surface are in contact with each other.

Abstract: A stretchable conductor includes a substrate with a first major surface and an elongate wire, wherein the substrate is an elastomeric material, the 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. Additionally, different methods of preparing said stretchable conductor are disclosed. Composite articles including said stretchable conductor in durable electrical contact with a conductive fabric are also disclosed.

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: Processes for automatic registration between a solid circuit die and electrically conductive interconnects, and articles or devices made by the same are provided. The solid circuit die is disposed at a registration area of a substrate. Fluid channels extend into the registration area and have a portion underneath the bottom surface of the solid circuit die. Electrically conductive traces are formed by flowing a conductive liquid in the channels toward contact pads on the bottom surface of the circuit die to obtain the automatic registration.
