National University of Singapore Researchers Create World First Garment Touchscreen
Researchers at the National University of Singapore have developed a revolutionary fibre that functions simultaneously as pixels and touch sensors. Assistant Professor Tural Khudiyev led the team that integrated these fibres into a sleeve to create the world's first touchscreen built directly into a garment.
The innovative sleeve displays images and video, responds to finger presses, and connects wirelessly to other devices. Despite its advanced electronic functionality, the fabric remains as washable, breathable, and flexible as ordinary clothing.
To build the garment display, the research team used a programmable method to create connection points along tiny, insulated wires. A laser exposes these locations, while controlled surface wetting guides molten solder to bond precisely at the programmed points.
This technique allowed the team to integrate more than 5,000 microchips through over 20,000 electrical connections. A thermal drawing approach then forms a multilayer fibre containing touch-sensitive and pixel layers within a thread measuring a millimetre thick and 10 metres long.
The prototype features 54 pixel fibres threaded into the forearm of a sleeve, forming a 168 mm by 105 mm display. The system refreshes 30 frames per second with 8-bit colour depth and allows each fibre to operate via its own control channel.
Alongside the pixel fibres, the team integrated peripheral fibres containing a microphone, a speaker, and sensors that track movement, magnetic north, temperature, and ambient brightness. These fibres support functions such as running a calculator, displaying photo galleries, playing videos, acting as a compass, and responding to voice commands.
The garment maintains its fabric qualities after 50 detergent washes in a typical washing machine and after 1,000 bends around a 5 mm radius. It matches the breathability of cotton, polyester, and denim while staying within established safety limits for skin contact.
Future developments could see the technology applied to continuous health monitoring combined with artificial intelligence. Khudiyev stated that healthcare represents a particularly promising application for the technology. Garment interfaces could eventually combine with artificial intelligence to enable personalised health monitoring, feedback, and assistance.
