The expansion of conventional prosthetic skin grafts has been quantified to be very low and
insufficient for treating large and severe burn injuries with small amounts of available donor …

This review serves as a comprehensive design strategy for designing quasi-zero stiffness
(QZS) mechanical metamaterials (MMs). It discusses their underlying deformation …

Auxetic metamaterials with excellent mechanical properties have attracted considerable
attention for use in various applications, especially for energy-absorption. In this work, novel …

This work investigates the mechanical response of bio-inspired titanium mechanical
metamaterials with negative Poisson's ratio evolved from rotating squares unit. The systems …

This paper presents for the first time two types of metamaterials based on the fragmentation–
reconstitution of rotating units in order to produce Poisson's ratio discontinuity at the original …

This research reports on the design, fabrication, and multiscale mechanical characterization
of flexible, planar mechanical metamaterials with tailorable mechanical properties. The …

In this paper, a novel auxetic structure with rotating squares with holes is investigated. The
unit cell of the structure consists of four units in the shape of a square with cut corners and …

The work presents a novel polyhedral mechanical metamaterial based on rotating triangular
prisms connected by their corners, which possesses the ability to attain large values of …

A mechanical metamaterial with anomalous thermal expansion and Poisson's ratio is
introduced herein by inspiration from the tangram puzzle. The on-axes coefficients of …

An auxetic metamaterial based on a semirotation system is designed herein by combining
rigid units of two different shapes, such that each unit cell consists of one nonrotating …
