    Abstract: A patterned article includes a polymeric layer having opposing first and second major surfaces and defining a plurality of through openings therein. For each through opening in at least a sub-plurality of the through openings, a metallic body is disposed in the through opening. The metallic body has a first outermost surface, an opposite second outermost surface and at least one lateral sidewall extending therebetween. The first outermost surface of the metallic body is substantially flush with the first major surface of the polymeric layer. Each lateral sidewall extends from the first outermost surface of the metallic body toward or to, but not past, the second major surface of the polymeric layer. The metallic body is substantially coextensive with the through opening in at least one cross-section parallel to the polymeric layer. The metallic bodies can be electrically isolated from one another.

    Abstract: The present disclosure provides articles having conformal layers and methods of making such articles. An article includes a first polymeric layer having a substantially planar major surface and an opposing major surface bonded to a second polymeric layer. One major surface of the second polymeric layer is conformal to the first polymeric layer while the opposing major surface defines a cavity having at least one wall. The second polymeric layer also has a channel connecting the cavity to at least one edge of the second polymeric layer or to the planar surface of the first polymeric layer. A surface of the cavity exhibits an advancing contact angle with water of less than 90 degrees. A method includes obtaining a tool having protruding features; disposing a first polymer on the protruding features; disposing a second polymer on the first polymer; and applying compression to the polymeric tooling, the first polymer, and the second polymer at an elevated temperature to form the article. The articles can be formed to have small cavities for use as precision fluidic devices, such as blood glucose testing strips.

    Abstract: Medical diagnostic devices or components thereof are described that comprise a microstructured surface that comprises peak structures and adjacent valleys wherein the valleys have a maximum width ranging from 1 to 1000 microns and the peak structures. In some embodiments (e.g. for improved cleanability) the peak structures of the microstructured surface have a side wall angle of 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-comers elements. The microstmctured surface of the medical diagnostic device typically comes in contact with multiple patients during normal use of the device, such as a stethoscope diaphragm. The microstmctured surface exhibits better microorganism (e.g. bacteria) removal when cleaned and/or provides a reduction in microbial touch transfer. Also described are methods of making and methods of use.

    Abstract: A battery system includes a plurality of battery cells and a heat exchanger including a plurality of channels for transporting fluid. The channels extend generally along a first direction and are arranged along an orthogonal second direction. Each channel in the plurality of channels has a major surface disposed to contact the fluid. An integrally formed polymeric sheet extending along the first and second directions includes at least a portion of the major surface of each channel in the plurality of channels. A major surface of the heat exchanger is in thermal contact with a major surface of the plurality of battery cells.
