Fifty-four fibres, each carrying 96 LEDs, form a 96 × 54 pixel display that responds to touch, survives 50 washes, and runs a calculator, a photo gallery and video at 30 frames per second.
Wearable electronics have mostly meant a rigid device strapped to a soft body: a watch, a patch, a sensor clipped to a waistband. Researchers at the National University of Singapore have taken a different route, building the electronics into the thread itself.
Writing in Nature, a team led by Assistant Professor Tural Khudiyev of the Department of Materials Science and Engineering at NUS College of Design and Engineering describes a fibre that both displays images and senses touch. Fifty-four of them woven into a sleeve make what the team says is the first touchscreen built into a garment.
Ninety-six LEDs per thread
Each pixel fibre is about 1 mm thick, up to 10 m long, and carries 96 light-emitting diodes along its length. Arranged side by side, 54 fibres produce a display of 96 × 54 pixels measuring 168 mm by 105 mm, refreshing at 30 frames per second with 8-bit colour.
The manufacturing numbers convey the scale of the problem: more than 5,000 chips integrated through over 20,000 electrical connections, all inside strands of material thin enough to be worn.
Touch sensing works mechanically. Pressing the fibre completes a circuit, and the nearest pixel lights up. Because each fibre has its own control channel, several touches can be registered at once, and a fault in one fibre leaves the rest working, a kind of redundancy that rigid displays lack entirely: a cracked screen is usually a dead screen.
“What made this possible was our ability to construct the GUI system from electronic building blocks in fibre form — similar to traditional yarn, but with the sophisticated electronic functionality built directly into the fibres,” Khudiyev said.
Why fibres are difficult
The obstacle was geometry. Electronics are designed for flat surfaces, where components can be laid out side by side and connected in two dimensions. A fibre offers no such surface.
“A fibre has a one-dimensional, axially symmetric geometry, which makes it difficult to build complex circuitry using approaches developed for conventional two-dimensional electronics,” Khudiyev said.
Fibre electronics are typically made by drawing: a larger assembly, called a preform, is heated and pulled into a long thin strand, with its internal structure preserved in miniature. The method can produce kilometres of fibre, but everything inside has to survive being stretched, and getting thousands of discrete chips positioned and connected along a thread is a different problem from printing a circuit on a board.
Interest in electronic textiles goes back decades, and most attempts have taken one of two forms: attaching conventional components to fabric, which works but leaves hard lumps in soft cloth, or weaving conductive threads to carry signals to a separate device. Building the display, the sensing and the processing into the fibre itself is the harder route, and the reason the result can be washed.
What the sleeve can do
The demonstration is not limited to lighting up. Alongside the pixel fibres, the team integrated peripheral fibres containing a microphone, a speaker, and sensors for movement, magnetic north, temperature and ambient brightness.
The functions they report read like a list from an early smartphone: a calculator, a photo gallery, video playback at 30 frames per second or 25 with synchronised audio, a compass, voice commands, image reception over Bluetooth, screen rotation and automatic brightness adjustment. The temperature sensor can display body temperature when the garment is placed under the arm.
The comparison is apt in another way. What makes this a graphical user interface rather than a flexible display is the combination of output and input in the same surface, which is what allowed touchscreens to replace buttons.
Resolution of this kind is enough for text, numbers and simple graphics, which is what the demonstrated functions require. A calculator needs digits and a compass needs a needle; neither needs the pixel density of a phone.
Fifty washes and a thousand bends
The claim that distinguishes a laboratory demonstration from a potential product is durability, and it is the part of the paper most likely to interest manufacturers.
After 50 detergent washes, light output and touch response were nearly unchanged. They were also nearly unchanged after 1,000 bends around a 5 mm radius, a tight fold for a textile.
The display is also as breathable as cotton, polyester and denim, and stays within established safety limits for skin contact. Breathability is not a trivial detail: a garment that traps heat and moisture is uncomfortable regardless of what it can display, which has sunk many attempts at electronic clothing.
The team notes that thinner versions of the fibres could be knitted, woven and embroidered using standard industrial machines, which would matter commercially. A material that requires bespoke manufacturing stays in the laboratory; one that runs through existing textile equipment has a route to production.
Clothes that monitor and respond
Khudiyev’s stated interest is medical.
“Healthcare is one particularly promising application,” he said. “A garment could continuously collect physiological information through fibre-based sensors and allow the wearer to access and interact with that information directly through their clothing. Combined with artificial intelligence (AI), this could enable personalised health monitoring, feedback and assistance.”
A garment that both senses and displays closes a loop that current wearables leave open. A patch that records heart rhythm has to send its data somewhere to be read; clothing with a screen in it could show the wearer what it has found, and take instruction back.
He is careful to frame the broader prospects as unknown rather than predicted. “Just as smartphones enabled applications that were difficult to imagine when they first appeared, garment GUIs could ultimately enable entirely new applications that do not yet exist,” he said.
The next steps the team identifies are higher resolution, integrated sensing and on-device AI. At 96 by 54 pixels, the current display is coarse by the standards of any modern screen, adequate for icons, numbers and simple images rather than fine detail.
