Multistable sheets with rewritable patterns for switchable shape-morphing

<p>This dataset contains raw data and images used in "Multistable sheets with rewritable patterns for switchable shape-morphing", published in Nature in September 2023. The Version of Record is available online at: http://dx.doi.org/10.1038/s41586-023-06353-5.</p><p>In this paper we demonstrate "groovy sheets": undulating metasheets which store &nbsp;memories of mechanical stimuli in patterns of self-stabilizing scars. After removing external stimuli, scars persist and force the sheet to switch to sharply selected curved, curled and twisted shapes. These stable shapes can be erased by appropriate forcing, allowing rewritable patterns and repeated and robust actuation. Our strategy is material-agnostic; extendable to other undulation patterns and instabilities; and scale-free, allowing applications from miniature to architectural scales.</p><p>The data in this replication package is organized in one directory for each main figure in the paper.
