Rationally designed architected materials have attained previously untapped territories in
materials property space. The properties and behaviours of architected materials need not …

Soft matter exhibits a multitude of intrinsic physico-chemical attributes. Their mechanical
properties are crucial characteristics to define their performance. In this context, the rigidity of …

Advances in additive manufacturing techniques have enabled the creation of stimuli-
responsive materials with designed three-dimensional (3D) architectures. Unlike biological …

Elastic properties of classical bulk materials can hardly be changed or adjusted in operando,
while such tunable elasticity is highly desired for robots and smart machinery. Although …

From stadium covers to solar sails, we rely on deployability for the design of large-scale
structures that can quickly compress to a fraction of their size,,–. Historically, two main …

Stimuli-responsive geometric transformations endow metamaterials with dynamic properties
and functionalities. However, using existing transformation mechanisms to program a single …

There is growing interest in voxelated matter that is designed and fabricated voxel by voxel,,–
. Currently, inkjet-based three-dimensional (3D) printing is the only widely adopted method …

In nature, cellular materials exhibit enhanced multifunctionalities driven mainly by their
sophisticated topologies and length scales. These natural systems have inspired the …

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 exhibit properties and functionalities that cannot be realized in
conventional materials. Originally, the field focused on achieving unusual (zero or negative) …
