Abstract: The present disclosure provides articles including an adhesive layer; a film layer bonded to the adhesive layer having a microstructured surface including numerous capillary channels; and a cover layer disposed on the capillary channels and attached to the adhesive layer. The adhesive layer is hydrophobic and includes an aperture for fluid (e.g., sweat) collection from a skin surface. The film layer also includes an aperture that overlaps the adhesive layer aperture to direct collected fluid to the capillary channels of the microstructured surface, which have a hydrophilic surface. Optionally at least one indicator chemistry can be present in the channels to facilitate optical (e.g., visual) determination of total fluid volume and/or concentration of at least one analyte in the fluid as a function of time.

Abstract: Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

Abstract: A substantially planar self-folding film assembly to generate a folded three-dimensional assembly. The assembly includes a flexible support substrate, adhesive elements, and folding members. The folding members include a base, a folding region, and a hinge adjacent each folding region attached at the base to the flexible support substrate by at least one of the adhesive elements. An array of polymer actuators is co-extensive, or shaped to be not co-extensive, with each of the flexible folding members. Upon activation by a patterned light to heat conversion layer, each polymer actuator is designed and configured to provide a displacement of the corresponding flexible folding member about each hinge.

Abstract: A condensation management apparatus comprises a microstructured film arranged to condense water vapor on an underside of a substantially horizontal surface. The film comprises channels disposed at least on a first major surface and configured to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the film. A capillary siphon structure of the film comprises a fold in the film, a condensate collection region proximate the fold, and a siphon region between the fold and a condensate release location of the film. At least a portion of a second major surface is attached to the underside of the substantially horizontal surface such that longitudinal openings of the channels of the condensate collection region are oriented towards a direction of gravity and the condensate release location is positioned lower along the direction of gravity than the condensate collection region.
