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.
