Once merely ancient arts, origami (ie, paper folding) and kirigami (ie, paper cutting) have in
recent years also become popular for building mechanical metamaterials and now provide …

Mechanical metamaterials are man-made structures with counterintuitive mechanical
properties that originate in the geometry of their unit cell instead of the properties of each …

Origami, the ancient Japanese art of paper folding, is not only an inspiring technique to
create sophisticated shapes, but also a surprisingly powerful method to induce nonlinear …

A rapidly expanding area of research in materials science involves the development of
routes to complex 3D structures with feature sizes in the mesoscopic range (that is, between …

Transforming flat sheets into three-dimensional structures has emerged as an exciting
manufacturing paradigm on a broad range of length scales. Among other advantages, this …

This review presents the state of the art in strain and ripple-induced effects on the electronic
and optical properties of graphene. It starts by providing the crystallographic description of …

Abstract Three-dimensional (3D) structures capable of reversible transformations in their
geometrical layouts have important applications across a broad range of areas. Most …

Shape plays an important role in defining the function of materials, particularly those found
in nature. Several strategies exist to program materials to change from one shape to …

Recent advances in lithography technology and the spread of 3D printers allow us a facile
fabrication of special materials with complicated microstructures. The materials are called …

Origami describes rules for creating folded structures from patterns on a flat sheet, but does
not prescribe how patterns can be designed to fit target shapes. Here, starting from the …
