Abstract:Origami is a traditional Japanese paper folding art that transforms planar patterns to three-dimensional (3D) structures. In our recent research, the design principles of origami are applied to fabricate 3D microscale structures and devices. Two-dimensional patterns created by lithography can spontaneously rise up out of the plane to yield 3D structures via compressive buckling on elastomer substrates, analogous to actions of children pop-up books. The new method is applicable to a wide range of materials, from device-grade single crystal silicon to biomaterials and cells. This picture shows four false-colorized scanning electron micrographs of origami-inspired 3D microstructures formed by compressive buckling. The top two images are the inverse pyramid and starfish structure made of bilayer of metal (gold) and polymer (epoxy) with scale bars of 200 'm. The bottom two images are the football structure and the three-floor Ziggurat architecture made from thin plastic film with scale bars of 20 mm. The complexity and capabilities of 3D structures formed by compressive buckling far exceed those created by traditional 3D printing techniques. The fabricated 3D microstructures can be further developed into microelectronic circuits, antennas and other biomimetic constructs due to their stretchability and compressibility.
