They strikingly resemble your own muscles. When grouped together, they can generate significant force and movement, all while remaining completely silent and hidden.<\/p>\n<p><span id=\"more-240189\"\/><br \/><iframe title=\"An electric motor in the form of a fiber\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/_P6QoE8zGw0?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><br \/>Each electrofluidic muscle fiber is only 2 millimeters thick and weighs roughly 2 grams. Inside, there\u2019s a little self-contained loop of highly unique liquid and a tiny pump the size of a toothpick. When you run some electricity through the pump, the liquid zooms ahead without any of the rotating elements or big storage tanks you\u2019d expect. On one side, the liquid accumulates and shortens the fiber, while on the other, it is sucked out and the fiber extends out, similar to how your biceps and triceps work together to bend your elbow.<\/p>\n<div class=\"aawp\">\n<div class=\"aawp-product aawp-product--horizontal\" data-aawp-product-asin=\"B07TZP8WWZ\" data-aawp-product-id=\"225491\" data-aawp-tracking-id=\"tec02e-20\" data-aawp-product-title=\"Unitree G1 Humanoid Robot\uff08No Secondary Development\uff09\">\n<div class=\"aawp-product__thumb\">\n<p>            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41V+YgoPxVL._SL160_.jpg\" alt=\"Unitree G1 Humanoid Robot\uff08No Secondary Development\uff09\"\/><\/p><\/div>\n<div class=\"aawp-product__content\">\n<p>            Unitree G1 Humanoid Robot\uff08No Secondary Development\uff09        <\/p>\n<div class=\"aawp-product__description\">\n<ul>\n<li>Sleek &amp; Durable Design: Standing at 132cm tall and weighing only approx. 35kg, the G1 is constructed with aerospace-grade aluminum alloy and carbon&#8230;<\/li>\n<li>High Flexibility &amp; Safe Movement: Boasting 23 joint degrees of freedom (6 per leg, 5 per arm), it offers an extensive range of motion.

Just that simple method prevents the development of microscopic air bubbles, allows the pump to operate at greater voltages, and allows the fiber to contract far more than it would otherwise. As a result, they can now achieve a 20% contraction in roughly a third of a second and generate 50 watts of power per kilogram, which is comparable to human skeletal muscle.<\/p>\n<p><iframe title=\"Electrofluidic Fiber Muscles on Science Robotics\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/8h4UEZTyres?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><br \/>Bundles of these fibers scale up quickly, with one configuration lifting and moving 4 kilograms, or 200 times its own weight, and stretching out around 30 millimeters. Another one, with several more pumps working simultaneously, elevates a lever arm at 180 millimeters per second and flings small items around in less than a tenth of a second. Woven into a cloth sleeve, the same fibers bend a robotic arm 40 degrees while remaining soft enough to allow for a friendly handshake.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/04\/11103119\/electrofluidic-muscle-fibers-artificial-mit-1.jpg\" alt=\"Electrofluidic Muscle Fibers Artificial MIT\" width=\"1280\" height=\"720\"\/><br \/><span><strong>Photo credit<\/strong>: Ozgun Kilic Afsar<\/span><br \/>Traditional motors in robots have large heavy cylinders near each joint, forcing designers to add a slew of gears and other connections that add bulk and make it difficult to achieve the fine movement required. However, these fibers may be stretched the whole length of a limb or an article of clothing, distributing weight evenly and allowing the structure to bend and twist in all the correct places. Everything remains sealed inside, allowing you to operate the device without the noise or mess of compressors and dangling hoses. This makes all types of wearing exoskeletons much more practical, and a sleeve knitted from the fibers allows you to lift huge objects without feeling stiff or being driven insane by incessant whirring. Prosthetic arms can achieve motion that is far more natural, quiet, and obedient.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2026\/04\/11103124\/electrofluidic-muscle-fibers-artificial-mit-2.jpg\" alt=\"Electrofluidic Muscle Fibers Artificial MIT\" width=\"1280\" height=\"720\"\/><br \/><span><strong>Photo credit<\/strong>:  Gabriele Pupillo, Ozgun Kilic Afsar<\/span><br \/>Ozgun Kilic Afsar, the project\u2019s lead student who also worked with academics from Politecnico di Bari and MIT\u2019s Media Lab, points out that previous fluid-powered systems all required large, heavy support equipment that was difficult to transport or wear. The new fibers address this by putting all of the necessary components directly inside the strand. Vito Cacucciolo, one of the team\u2019s professors, observes that these fibers allow engineers to distribute actuators throughout a robot rather than grouping them all at the joints.<br \/><span>[Source]<\/span><\/p>\n<\/p><\/div>\n<p> Electricity Sparks Movement in MIT&#8217;s New Artificial Muscle Fibers<br \/>\n<br \/>#Electricity #Sparks #Movement #MITs #Artificial #Muscle #Fibers<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists from MIT\u2019s Media Lab have developed extremely thin strands that wrap and unravel at&#8230;<\/p>\n","protected":false},"author":1,"featured_media":6422,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[1179,4406,6067,6066,4452,276,5793],"class_list":["post-6421","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-tech","tag-artificial","tag-electricity","tag-fibers","tag-mits","tag-movement","tag-muscle","tag-sparks"],"featured_image_urls":{"full":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit.jpg",1280,1280,false],"thumbnail":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit-150x150.jpg",150,150,true],"medium":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit-300x300.jpg",300,300,true],"medium_large":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit-768x768.jpg",640,640,true],"large":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit-1024x1024.jpg",640,640,true],"1536x1536":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit.jpg",1280,1280,false],"2048x2048":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit.jpg",1280,1280,false],"covernews-featured":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit-1024x1024.jpg",1024,1024,true],"covernews-medium":["https:\/\/news678.top\/wp-content\/uploads\/2026\/04\/electrofluidic-muscle-fibers-artificial-mit-540x340.jpg",540,340,true]},"author_info":{"display_name":"admin","author_link":"https:\/\/news678.top\/?author=1"},"category_info":"<a href=\"https:\/\/news678.top\/?cat=8\" rel=\"category\">Tech<\/a>","tag_info":"Tech","comment_count":"0","_links":{"self":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts\/6421","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=6421"}],"version-history":[{"count":0,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/posts\/6421\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=\/wp\/v2\/media\/6422"}],"wp:attachment":[{"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=6421"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=6421"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news678.top\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=6421"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
