  • Patent number: 11752745
    Abstract: Disclosed is a stretchable, three-dimensional tubular structure formed due to processing-induced wrinkles to result in a platform for stretchable interactive electronics. The three-dimensional tubular structure is fabricated simply by releasing a pre-stretched two-dimensional film-substrate precursor, and the resulting wrinkled surface shows a strong directional dependence that drives the tube formation.

  • Patent number: 10950146
    Abstract: A moisture responsive system comprising: a thin film polymer layer, wherein the thin film polymer comprises a hydrophilic polymer; and a substrate polymer layer, wherein the substrate polymer comprises a hydrophobic elastomer; wherein the thin film polymer layer is attached to the substrate polymer layer at a bottom surface of the thin film polymer layer and the thin film polymer layer has a top surface opposing the bottom surface is provided. A method of making a moisture responsive system, comprising: applying a thin film polymer layer to a foundation; applying a substrate polymer layer on the thin film polymer layer; curing the substrate polymer layer to form a thin film polymer layer/substrate polymer bilayer; and removing the thin film polymer layer/substrate polymer bilayer from the foundation is provided. A method of using such a moisture responsive system by applying moisture to the moisture responsive system is provided.
