NANO-KIRIGAMI

Kirigami, although coined in 1962 from Japanese words kiri (meaning "cut") and kami (meaning "paper"), is actually one of the most traditional Chinese arts (named "paper-cuts" or "jianzhi") that has been widely used in window decorations, gift cards, festivals, ceremonies, etc., since 1500 years ago. Through cutting and folding flat objects into 3D shapes, the knowledge of kirigami has recently aroused tremendous interests in both sciences and technologies, including deployable designs of solar arrays, biomedical devices and micro-/nano- electromechanical systems...
