A self-folding sheet, transforming itself into a boat
Researchers at Harvard University and MIT have created an origami-inspired “smart sheet” that can fold itself into various shapes, without any external manipulation. The sheet is composed of rigid triangular tiles that are linked together by elastomer joints, and studded with flexible electronics and thin foil actuators (motorized switches). The scientists foresee a day when such sheets could be used to create things like smart tools, that could take the form of anything from a wrench to a tripod.
