A toolkit for transformable materials: How to design materials with reprogrammable shape and function | Wyss Institute

By Leah Burrows (CAMBRIDGE, Massachusetts) - Metamaterials - materials whose function is determined by structure, not composition - have been designed to bend light and sound, transform from soft to stiff, and even dampen seismic waves from earthquakes. But each of these functions requires a unique mechanical structure, making these materials great for specific tasks, but difficult to implement broadly.
