MIT<\/span>Material acts like strands of spaghetti tangled in a latticeMIT<\/span><\/p><\/div>\n

A new synthetic metamaterial created at the Massachusetts Institute of Technology (MIT) reconciles two properties that are incompatible in conventional materials: strength and elasticity\u2014typically, the stronger a material, the less stretchy it is. The new metamaterial combines rigid microscopic structures in the form of grids or lattices with a softer woven architecture in the form of spirals that intertwine around each lattice. The two networks are made from a polymer similar to plexiglass (a type of transparent plastic derived from petroleum) and printed at the same time using high-precision laser 3D printing. The double network can stretch to three times its original length without completely breaking, which is 10 times further than the same plastic in a lattice pattern. Strategically placed holes in the material make it even more resistant to breakage. The material could be used to make stretchy ceramics, glasses, or metals, tear-resistant fabrics, flexible semiconductors, electronic chip packaging, and scaffolds on which cells are grown for tissue repair (Nature Materials<\/em><\/a>, April 23).<\/p>\n","protected":false},"excerpt":{"rendered":"Researchers develop synthetic metamaterial that combines seemingly incompatible properties","protected":false},"author":475,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[228,2413],"coauthors":[785],"class_list":["post-567858","post","type-post","status-publish","format-standard","hentry","category-notes","tag-engineering","tag-technology"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/567858","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=567858"}],"version-history":[{"count":3,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/567858\/revisions"}],"predecessor-version":[{"id":569718,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/567858\/revisions\/569718"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=567858"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=567858"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=567858"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=567858"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
