- History of kirigami
Kirigami, i.e. the cutting and folding of flat objects to create versatile shapes, is one of the most traditional Chinese arts (named “jianzhi”) that plays important roles in people’s daily life, such as the paper-cuts used frequently in window decorations, gift cards, festivals, and various ceremonies. The symbol role of kirigami and origami (origami does not involve the cutting process), as recorded in the famous Chinese book of “Records of the Grand Historian”, existed much earlier before the invention of paper (around 105 A.D. in China). For example, around 1055~1021 B.C., the King Cheng of Zhou Dynasty patterned one leaf of a Chinese parasol tree and treated it as a pledge to award his brother a territory. The earliest example of paper-based kirigami, named “Flowery Horses”, was found in a relic of the Chinese Northern Dynasties (386-581 A.D.). During the 6th century, paper was introduced into Korea and then into Japan, where the kirigami and origami emerged as special symbols in religious rituals and important ceremonies. Different from ancient Chinese who treated kirigami and origami as phenomenological skills, Japanese pioneers recorded and analyzed the detailed methods of these ancient arts since 17th century, benefiting from which the knowledge of kirigami and origami has been well accumulated and communicated in Japan and other regions of the world. In the West, kirigami and origami might have been developed independently as ceremonial symbols in 15th and later on became popular as gifts, occupations or art forms among the social elites. It was in 1962 that the English word “kirigami” was coined by Florence Temko from Japanese words kiri (meaning “cut”) and kami (meaning “paper”).
- Modern applications of kirigami/origami
Applicable “Miura-ori” pattern [Phys World 28, 21-24 (2015)], the satellite solar panels [J. Mech. Des. 135, 111005 (2013)], the mini-robot [Science 345 , 644 ( 2014 )] and the graphene kirigami [Nature 524, 204-207 (2015)].
- Application examples of 3D suspending nanodevices
Suspended 3D subunits have been successfully employed by commercial digital micromirror devices (DMD, Texas Instruments) in digital light processing projection (DLP) and related 3D printing industry, as well as in mirasol display (Color e-Reader, Qualcomm).
