Plants provide model for new shape-changing materials
...act, we hope to move on from the morphing wings to other
applications that require structures that can produce large shape changes. An example might be a compact container that will deploy into an antenna after it is transported to a particular location," Leo said. "Biological systems are excellent templa...
