When injected with water, the hollow robots inflate and move as they were designed to. By stretching out or curling up, they can, for example, kick a ball or retrieve a live fish inside an aquarium and then let go of it. Composed mostly of water mixed with polymers, hydrogel is a tough, rubbery material that is nearly transparent, although it can be dyed. \u201cHydrogels are. . .biocompatible and can form more friendly interfaces with human organs,\u201d MIT professor and team leader Xuanhe Zhao said in a press release about the study. \u201cWe are actively collaborating with medical groups to translate this system into soft manipulators such as hydrogel \u2018hands,\u2019 which could potentially apply more gentle manipulations to tissues and organs in surgical operations.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Hydrogel robots can carry out tasks in water","protected":false},"author":475,"featured_media":0,"comment_status":"open","ping_status":"open","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":[228,243],"coauthors":[785],"class_list":["post-243640","post","type-post","status-publish","format-standard","hentry","category-notes","tag-engineering","tag-innovation"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/243640","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=243640"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/243640\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=243640"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=243640"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=243640"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=243640"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
