A touchscreen you can wear? Indian researcher helps develop a washable smart sleeve

Researchers at the National University of Singapore have developed a touchscreen sleeve that can play videos, respond to touch and survive 50 machine washes. Indian researcher Swetika Chaturvedi is part of the team behind the invention.Assistant Professor Tural Khudiyev (second from right) of the NUS College of Design and Engineering, with team members Heng Fu, a PhD student (right), Ziang Li, a PhD candidate (second from left), and Swetika Chaturvedi, a research associate (left).

Instead, you simply tap your sleeve.Scientists at the National University of Singapore (NUS) have developed a touchscreen that can be woven into clothing, turning ordinary fabric into a wearable digital interface. The prototype can display images and videos, respond to touch and connect wirelessly to other devices. Even more remarkably, it retained nearly the same light output and touch response after 50 machine washes.Indian researcher Swetika Chaturvedi, a research associate at NUS, is among the team members behind the invention.A TOUCHSCREEN MADE FROM THREADPublished in Nature on October 21, 2026, the research introduces a flexible textile display built using specially engineered electronic fibres. The researchers describe it as the world's first touchscreen integrated into a garment. Unlike conventional screens, which rely on rigid panels, the new technology packs electronic components into fibres that can be incorporated into fabric.The team, led by Assistant Professor Tural Khudiyev of NUS, integrated 54-pixel fibres into a sleeve to create a display measuring 168 mm by 105 mm. The screen has a resolution of 96 54 pixels and can refresh at 30 frames per second. Pressing the fibre activates its touch-sensitive layer, allowing the system to detect where a finger lands and light up the corresponding pixel.

It can play videos, run a calculator, show a photo gallery, function as a compass, respond to voice commands and receive images over Bluetooth.The researchers also incorporated fibres carrying a microphone, speaker and sensors that measure temperature, movement, surrounding brightness and magnetic direction.A temperature sensor positioned under the arm can measure body temperature and display the reading on the sleeve. This could eventually make the technology useful for health monitoring, particularly when combined with other wearable sensors.AND YES, IT CAN BE WASHEDWearable electronics often face a basic problem: ordinary clothing gets bent, stretched and washed regularly. A delicate electronic display would struggle to survive that treatment.The NUS team reports that its prototype retained nearly unchanged display brightness and touch response after 50 detergent washes. It also withstood 1,000 bends around a radius of just 5 mm.The display remains flexible and breathable, behaving much like conventional fabric.The technology is still a research prototype, not a ready-to-buy replacement for smartphones. The team's next goals include improving screen resolution and integrating more sensing capabilities and artificial intelligence.If those advances work, clothing could eventually become more than something we wear. It could also become a screen, a sensor and a direct interface with our digital lives.- Ends
