National University of Singapore researchers develop touchscreen fabric

Researchers at the National University of Singapore (NUS) have developed the first functional touchscreen integrated directly into garment fabric. Led by Associate Professor Tural Khudiyev, the team created a sleeve using 54 pixel fibers that act as both pixels and touch sensors.

The technology utilizes 96 LEDs per fiber to form a 96 by 54 pixel display, measuring 168 by 105 millimeters. The system supports an 8-bit color depth and a 30 frames per second refresh rate. Because each fiber has an independent control channel, a single broken fiber does not affect the rest of the display, and the system can register multiple simultaneous touches.

Unlike previous prototypes, this textile remains flexible, breathable, and washable, having successfully passed tests of 50 conventional machine washes and 1,000 bends. The research, published in the journal Nature, suggests that scaled versions of this technology could allow clothing to display health data, play videos, or function as a compass and calculator without the need for rigid internal panels.
