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”.

一个刚性的物体可以不弯曲和拉伸地缠绕在一个球上吗？一张平板能变成一个能承受任何力的三维装置吗？这种3D形状可以可逆地熨烫回原始板材而不会损坏吗？在目前的材料中，我们找不到答案。相比之下，在多种应用中寻求可以拉伸和折叠、包装和打开以及急剧改变体积和形状的产品。例如，可部署的太阳能电池板只是其中之一，但其他许多跨学科和长度规模存在，都在追逐材料科学和工程的圣杯：“可以变形以在不同配置中工作的材料”。
