Researchers Threaded a Working Touchscreen Into a Garment Sleeve

Researchers at the National University of Singapore have built a fiber that works as a row of pixels and as a touch sensor at the same time, and threaded 54 of them into the forearm of a sleeve to make a screen a finger can operate. Heng Fu and colleagues, supervised by Tural Khudiyev of the university's Department of Materials Science and Engineering, published the work Oct. 21, 2026, in Nature.

NUS says the fibers enable garments that act as a direct interface to a wearer's health data and their digital devices, with no rigid screen involved. Khudiyev named healthcare as one promising application, with a garment gathering body data through fiber sensors and the wearer reading it through the clothing itself.

Per the university's announcement, a laser exposes contact points along insulated wires and molten solder is guided to bond only there, which lets the team join more than 5,000 chips along a single thread. The strip of chips was then drawn out under heat, forming the pixel and touch layers inside a fiber one millimeter thick. Pressing the fiber completes a circuit, and the nearest pixel lights up.

The fibers in the prototype form a 96 by 54 pixel display that refreshes 30 times a second. NUS said the sleeve runs a calculator, a photo gallery, a compass and video, accepts images over Bluetooth and answers voice commands. The university also reported that light output and touch response were nearly unchanged after 50 washes in an ordinary washing machine, and that the display is as breathable as cotton or denim.

NUS calls the sleeve the world's first touchscreen built into a garment. The team has posted its source data and analysis code on GitHub, and the paper in Nature credits funding from Singapore's Ministry of Health through its National Medical Research Council. The group said its next step is higher resolution, more sensing and on-device AI in the same textile.
