Description:
In origami, form follows the sequential spatial organization of folds. This requires continuous intervention and raises a natural question: Can origami arise through self-organization? We answer this affirmatively by examining the possible physical origin for the Miura-ori leaf-folding patterns that arise naturally in insect wings, leaves, and other laminae-like organelles. In particular, we point out examples where biaxial compression of an elastically supported thin film, such as that due to differential growth, shrinkage, desiccation, or thermal expansion, spontaneously generates these patterns, and we provide a simple theoretical explanation for their occurrence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mahadevan, L -- Rica, S -- New York, N.Y. -- Science. 2005 Mar 18;307(5716):1740.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Engineering and Applied Sciences and Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, MA 02138, USA. lm@deas.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15774751" target="_blank"〉PubMed〈/a〉
