The data stream is fed to a robotic hand, which mirrors the wearer’s gestures without perceptible lag.\n\nThe system sidesteps cameras or gloves, using sound waves that penetrate the skin to track bone and tendon motion. Because the hardware stays on the wrist, it works even when the hand is hidden or in bright sunlight. The researchers published the results in *Nature Electronics* and demonstrated a live tele‑operation scenario.\n\nIf the approach scales, developers could replace bulky motion‑capture rigs with a discreet band for VR, remote surgery, or industrial robot control. The low‑profile design also opens possibilities for assistive devices that translate subtle finger movements into command signals.\n\nFor now, the demo is a lab proof‑of‑concept; commercial products will need to address power consumption and robustness before everyday use.","[\"wearables\",\"robotics\",\"human-computer interaction\"]","2026-06-09T19:17:53.000Z","2026-06-09T20:35:19.809Z","2026-06-09T22:22:16.297Z","published",null,[],"https:\u002F\u002Fcdn.xyz.onl\u002Farticle-images\u002Fultrasound-wristband-reads-finger-motions-drives-robot-hand-live.webp",[26,27,28],"wearables","robotics","human-computer interaction",[30],{"name":31,"url":32},"The Next Web","https:\u002F\u002Fthenextweb.com\u002Fnews\u002Fmit-ultrasound-wristband-hand-tracking-robot-control",0]
