It captures what the team describes as 22 degrees of freedom — covering every major way a human hand can bend, rotate, and reposition its fingers. That data gets relayed to a robotic hand, which mirrors the movements without a physical connection to the fingers themselves. No instrumented glove required.\n\nThe wrist is a logical place to instrument a hand. The tendons and muscles that move the fingers all pass through the wrist on their way out, so a sensor worn there can infer a surprising amount about finger position without touching the hand directly. If that signal is reliable and low-latency enough to drive a robot in real time — and the Nature Electronics paper suggests it is — the approach could matter for prosthetics, remote surgery, and industrial teleoperation, all of which currently depend on systems that are either bulky, camera-dependent, or both.\n\nPeer review at a serious journal is a meaningful bar to clear. What the source doesn't address is how the system holds up across different hand sizes, or whether performance degrades outside controlled lab conditions — two questions that tend to separate interesting research from anything that ships.","[\"robotics\",\"wearables\",\"research\",\"ultrasound\"]","2026-06-09T19:17:53.000Z","2026-06-09T20:35:19.809Z","2026-06-18T07:59:52.031Z","published",null,[],"https:\u002F\u002Fcdn.xyz.onl\u002Farticle-images\u002Fultrasound-wristband-reads-finger-motions-drives-robot-hand-live.webp","science",[27,28,29,30],"robotics","wearables","research","ultrasound",[32],{"name":33,"url":34},"The Next Web","https:\u002F\u002Fthenextweb.com\u002Fnews\u002Fmit-ultrasound-wristband-hand-tracking-robot-control",0,{"sections":37},[38,43,48,53,58,63,68,73,77,82,87,92,97,102],{"name":39,"slug":40,"count":41,"latest_published_at":42},"AI","ai",2602,"2026-07-18T18:30:00.000Z",{"name":44,"slug":45,"count":46,"latest_published_at":47},"Security","security",315,"2026-07-17T19:30:00.000Z",{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Policy","policy",169,"2026-07-17T19:49:53.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":62},"Hardware","hardware",126,"2026-07-16T20:09:48.000Z",{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",94,"2026-07-16T16:29:46.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Software","software",72,"2026-07-17T09:42:05.000Z",{"name":74,"slug":25,"count":75,"latest_published_at":76},"Science",66,"2026-07-10T10:29:37.000Z",{"name":78,"slug":79,"count":80,"latest_published_at":81},"Dev Tools","dev-tools",60,"2026-07-16T16:59:13.000Z",{"name":83,"slug":84,"count":85,"latest_published_at":86},"Startups","startups",42,"2026-07-16T16:30:35.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":103,"slug":104,"count":105,"latest_published_at":106},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
