a, b Reversible switching of a tuneable 3D SRR metasurface in the infrared (IR) wavelength region83. c Kirigami nanocomposites as wide-angle diffraction gratings89. d Schematic of a Miura-ori chiral metamaterial, in which the chirality can be switched by changing the deformation direction27. e Schematic illustration of (left) the 2D precursor and (right) two 3D kirigami-based metamaterials with opposite chirality110. f Displacement of the spiral structure with respect to the applied pressure, which deformed the planar spiral to a left-handed or right-handed helix111. The lateral size of each spiral is 150 μm. g Mechanical compression and release of a three-arm pinwheel array, which changed the height of the pinwheels and enabled reversible switching between chiral transmission and non-chiral transmission108.
