Programmable Self‐Locking Origami Mechanical Metamaterials
Advanced Materials, 2018 AbstractDeveloping mechanical metamaterials with programmable properties is an emerging topic receiving wide attention. While the programmability mainly originates from structural multistability in previously designed metamaterials, here it is shown that nonflat‐foldable origami provides a new platform to achieve programmability via its intrinsic self ...
