In a proof-of-concept study a team of researchers in the US (North Carolina State University, Yale University) cut bulk materials into spatially closed-loop to construct a new class of 3D kirigami metamaterials. The module is transformable with multiple degrees of freedom that can transform into versatile distinct daughter building blocks. Depending on how the cubes are connected to each other, the building blocks can be folded into more than 300,000 different designs. Their conformable assembly creates a wealth of reconfigurable and disassemblable metamaterials with diverse structures and unique properties, including reconfigurable 1D column-like materials, 2D lattice-like metamaterials with phase transition of chirality, as well as 3D frustration-free multilayered metamaterials with 3D auxetic behaviors and programmable deformation modes. The technique could be used in applications such as lightweight construction materials for buildings, components for modular robotics and wave guiding in acoustic metamaterials…read more.
