Kirigami cools electronics

Scientists from SANKEN (The Institute of Scientific and Industrial Research) at Osaka University, Oita National College of Technology, and Tokyo Polytechnic University demonstrated enhanced passive convective cooling using cellulose nanofiber films designed based on kirigami, a traditional paper design form similar to origami. The difference when compared with origami is that, in addition to folding, kirigami involves cutting the paper as well. This work may enable small flexible electronic devices to operate without overheating.
