Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201500716-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>By prescribing asymmetric ligaments</bold> with different arrangements in elastomeric porous membranes of pre‐twisted kagome lattices, the buckling instability is avoided, allowing for smooth and homogenous structural reconfiguration in a deterministic fashion. The stress–strain behaviors and negative Poisson's ratios can be tuned by the pre‐twisting angles. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjkz034dk" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
