Kirigami/origami: Unfolding the new regime of advanced 3D micro-/nanofabrication with ‘folding’

Emerging kirigami/origami techniques, neither subtractive nor additive, provide an automated fashion for 3D micro-/nanofabrication through folding, bending and twisting of 2D materials/structures. Aiming to shine a glimpse on this new regime, a research team in China reviewed some of the latest kirigami/origami-like 3D fabrication techniques in micro-/nanoscale, including the stimulus strategies and potential applications on reshaping 2D materials, optical reconfigurations, etc. The review is helpful to build new platforms for both physics and application exploration.
