Overview
- The Nature paper published 21 October 2026 reports that researchers at the National University of Singapore built a working washable sleeve that acts as a touchscreen display.
- The team combined a new programmable interconnection method with thermal drawing to place roughly 5,000 microchips and about 20,000 electrical connections along long, multilayer fibers.
- The prototype uses 54 pixel fibers with 96 LEDs per fiber to form a 96×54‑pixel, 168×105 mm display that refreshes at 30 frames per second and supports multi‑touch input.
- Peripheral fibers in the garment carry a microphone, speaker and sensors for motion, magnetics, temperature and ambient light, and the system can play video, respond to touch and link over Bluetooth.
- Tests showed nearly unchanged light output and touch response after 50 machine washes and 1,000 tight bends, and the authors say smaller chips and thinner fibers are needed next for higher resolution and mass manufacture.
