Methods and apparatuses for roll coating are provided. The roll coating system () includes a coating roll () having a deformable inner layer () with a surface thereof covered by a deformable outer layer (), the inner layer being softer than the outer layer. A substrate () is conveyed to the nip () between the coating roll and a back-up roll (). A metered coating material is transferred from the coating roll to a patterned surface structure () of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.

Roll coating using metered coating roll including deformable layers

Methods and apparatuses for screen or stencil printing a pattern on a substrate are provided. The substrate () has its major surface in contact with a first major surface () of a stencil shell () having apertures (). A coating material is disposed onto the second major surface () of the stencil shell () to flow through the apertures () to contact the substrate (), where the coating material is at least partially cured. The substrate () is separated (C) from the first major surface () of the stencil shell () after the curing () and a pattern () of the at-least-partially-cured coating material is formed on the substrate ().

Methods and systems for stencil printing

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.

Stretchable conductors

Diagnostic devices for quantitative or qualitative analysis of a sample fluid including an analyte include at least two portions made from a hydrophilic material. The planar portions are stacked on each other and each occupy a different and substantially parallel plane to form a three-dimensional structure. At least one of the planar portions includes a hydrophobic region formed by applying a low surface energy material that extends through a thickness of the substrate portion from a first major surface to a second major surface thereof. The hydrophilic regions in the overlying substantially parallel substrate portions can be aligned with each other such that a fluid is passively transported between adjacent hydrophilic regions to provide a sample flow path between adjacent substrate portions.

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.
