Most reconfigurable materials can toggle between two distinct states and require a persistent external stimulus to change from one shape to another and stay that way. Using two-photon lithography a team of researchers in the US (Caltech, GeorgiaTech) designed a silicon-coated lattice with microscale straight beams that bend into curves under electrochemical stimulation, taking on unique mechanical and vibrational properties. They built in defects in the architected material system, based on a pre-arranged design. The material has potential for energy storage systems, provides a novel pathway for development of next generation smart batteries with both increased capacity and novel functionalities and open the way to beyond-intercalation battery electrodes, tunable phononic crystals and bio-implantable devices…read more.
