Can a rigid objet wrap around a ball without bending and stretching? Can a flat sheet be transformed into a three-dimensional device that can take any force applied to it? And can this 3D shape be reversibly ironed back to the original sheet without damage? In current materials, we find no answer. In contrast, products that can stretch and fold, pack and unpack, as well as change drastically volume and shape are sought in a manifold of applications. Deployable solar panels, for example, are just one of them, but many others exist across disciplines and length scale, all chasing the Holy Grail of material science and engineering: “materials that can shape-transform to work in diverse configurations”.

刚性物体可以在不弯曲和伸展的情况下包裹球吗？平板能变成可以承受任何力的三维装置吗？这种3D形状可以被可逆地熨回到原来的板材上而不会损坏吗？在目前的材料中，我们找不到答案。相比之下，可以拉伸和折叠、打包和拆包以及大幅改变体积和形状的产品在各种应用中都被寻求。例如，可展开的太阳能电池板只是其中之一，但还有许多其他的电池板存在于不同的学科和长度范围内，都在追逐材料科学和工程的圣杯：“可以变形以在不同结构下工作的材料”。
