Researchers have showcased the world’s first touchscreen built into a garment. The team from the National University of Singapore’s College of Design and Engineering (CDE) have developed a fibre that functions as pixels and senses touch at the same time, integrating 54 of them into a sleeve to create the world’s first touchscreen built into a garment.

“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,” said Asst Prof Khudiyev.

The team revealed that the sleeve displays images and video, responds to finger presses and connects wirelessly to other devices, yet stays as washable, breathable and flexible as ordinary clothing. The team’s invention enables the creation of garments that act as a direct interface to a wearer’s health data and their digital devices, with no rigid screen involved. 

The screens that people are familiar with, such as those on phones and laptops, typically present graphical user interfaces (GUIs) on flat, rigid panels that display information and enable interaction. Textiles, woven from one-dimensional fibres, have never matched this capability. A full-colour, touch-sensitive display that can be threaded like yarn was, until now, out of reach, according to researchers. To build a fibre-enabled garment display, the NUS team developed a programmable method that creates connection points along tiny, insulated wires exactly where each microchip needs them. A laser exposes these locations, while controlled surface wetting guides molten solder to bond only at the programmed points.
