  • HYDROGEL COMPOSITE INK FORMULATION AND METHOD OF 4D PRINTING A HYDROGEL COMPOSITE STRUCTURE
    Publication number: 20180251649
    Abstract: A method of 4D printing comprises depositing a layer of filaments in a predetermined arrangement on a flexible substrate. Each filament comprises a hydrogel matrix and a plurality of anisotropic filler particles embedded therein. The filaments contact the flexible substrate at one or more contact regions. The layer of filaments is hydrated, and the filaments swell in size while remaining in contact with the flexible substrate at the contact regions. The flexible substrate is thereby induced to adopt a predetermined curved shape.

  • Patterning structures using deformable substrates
    Patent number: 8557341
    Abstract: Aspects of the present invention describe soft imprint lithography methods capable of preparing structural features on surfaces. Disclosed methods include surmounting a deformable substrate, having an original form, with a composition, wherein the deformable substrate is capable of achieving at least one predetermined deformed state; predictably deforming said deformable substrate from its original form to the at least one predetermined deformed state; and transferring at least a portion of the composition surmounting the deformed substrate to a receiving substrate.
