Auxetics are a class of structural metamaterials with a negative Poisson's ratio. In
comparison to conventional structures, auxetic structures are proven to exhibit several …

Composite materials have now been adopted in a wide range of applications, primarily due
to their weight-saving potential. Overwhelmingly so, these materials have been used in …

Mechanical metamaterials offer exotic properties based on local control of cell geometry and
their global configuration into structures and mechanisms. Historically, these have been …

Lightweight yet strong cellular structural materials have long been sought for varied
engineering applications due to the outstanding performance, and have been existing in …

Ultralight materials present an opportunity to dramatically increase the efficiency of load-
bearing aerostructures. To date, however, these ultralight materials have generally been …

Versatile programmable materials have long been envisioned that can reconfigure
themselves to adapt to changing use cases in adaptive infrastructure, space exploration …

Programmable architected materials with the capabilities of precisely storing predefined
