  • Patent number: 11839998
    Abstract: Three-dimensional (3D) hierarchical morphologies widely exist in natural and biomimetic materials, which impart preferential functions including liquid and mass transport, energy conversion, and signal transmission for various applications. While notable progress has been made in the design and manufacturing of various hierarchical materials, the state-of-the-art approaches suffer from limited materials selection, high costs, as well as low processing throughput. Herein, by harnessing the configurable elastic crack engineering-controlled formation and configuration of cracks in elastic materials, an effect normally avoided in various industrial processes, the present invention provides a facile and powerful technique to enable the faithful transfer of arbitrary hierarchical structures with broad material compatibility and structural and functional integrity.

  • Publication number: 20050154567
    Abstract: The present invention relates to three-dimensional microstructures and methods for making these microstructures, particularly microstructures having integral features less than about 1 mm. Examples of these microstructures include trusses. The microstructures can be prepared from two-dimensional structures having a deformable portion. Thus, by applying a deformation along these deformable portions, e.g. bending, a third-dimension can be created. The deformable portions can comprise thinner dimensions than more rigid portions to allow facile deformation to a predetermined angle or orientation. Electroplating at least a portion of the three-dimensional microstructure with a metal coating allows the formation of integral features in addition to covering any defects formed by the deformation and/or strengthening any thin components. The initial two-dimensional microstructure can be prepared by various patterning methods such as soft lithographic methods.
