National University of Singapore researchers develop touchscreen garment

Researchers at the National University of Singapore (NUS) have developed a smart textile sleeve that integrates a functional touchscreen directly into the fabric. Unlike traditional wearable technology that relies on rigid devices strapped to the body, this system uses 54 specialized electronic fibers woven into a garment to create a 96 × 54 pixel display.

Each fiber is approximately 1 mm thick and can be up to 10 meters long, containing 96 light-emitting diodes (LEDs). The technology utilizes a programmable method to integrate over 5,000 chips and 20,000 electrical connections within the threads. The display is capable of running a calculator, showing photo galleries, playing video at 30 frames per second, and functioning as a compass.

In addition to visual output, the fibers sense touch mechanically; pressing the fabric completes a circuit that triggers the nearest pixel. The prototype has demonstrated durability by maintaining performance after 50 machine wash cycles. This development allows garments to serve as direct interfaces for digital devices and health data without the need for rigid screens.
