Published in Nature on October 21, 2026, a National University of Singapore (NUS) study describes a touch-sensitive display woven into a sleeve. In the video demonstration, playback runs at 30 frames per second (fps) without audio and 25 fps with synchronized audio. The underwater demonstration involves an individual pixel fibre.

A touchscreen woven into a sleeve
The prototype places 54 pixel fibres in the forearm of a sleeve. Each fibre carries 96 LEDs, and together they form a 96 × 54-pixel display measuring 168 × 105 mm, or about 6.6 × 4.1 inches. NUS describes the display as refreshing at 30 fps with 8-bit color. NUS
A display’s refresh rate counts how often its screen updates; video playback rate counts the frames in the video. Nature’s playback description specifies separate rates for the silent and synchronized-audio modes:
| Playback condition | Video frame rate |
| Without audio | 30 fps |
| With synchronized audio | 25 fps |
The sleeve also demonstrates calculator, photo-gallery and compass interfaces, along with voice-triggered control, Bluetooth image transfer, automatic rotation and brightness adjustment, and temperature sensing and display. NUS describes a touch-sensitive layer beneath the LEDs: pressing a fibre completes a circuit, and the signal identifies the touch location so the nearest pixel responds. NUS
Read the video rate together with its playback condition: 25 fps is the synchronized-audio mode, while 30 fps applies to silent video.
NUS reports that the sleeve’s light output and touch response remained nearly unchanged after 50 detergent washes in a typical washing machine and 1,000 bends around a 5 mm radius. NUS
The water demonstration used a pixel fibre
Nature’s supplementary-video description identifies an individual pixel fibre operating while submerged in water. The reported demonstration is at the fibre level.
