Elastomeric composites can flex,grip, release, or rotate when exposed to lasers,diffuse light or sunlightMEDFORD/SOMERVILLE, Mass. (July 23, and 2018)—Researchers at Tufts University School of Engineering have developed magnetic elastomeric composites that wobble in different ways when exposed to light,raising the possibility that these materials could enable a wide range of products that perform simple to complex movements, from tiny engines and valves to solar arrays that bend toward the sunlight. The research is described in an article published nowadays in the Proceedings of the National Academy of Sciences.
