A team of researchers from Nottingham Trent University (UK), Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Free University of Bozen-Bolzano (Italy) has created washable and durable magnetic field sensing electronic textiles – thought to be the first of their kind – which they say paves the way to transform use in clothing, as they report in the journal Communications Engineering (DOI: 10.1038/s44172-025-00373-x). This technology will allow users to interact with everyday textiles or specialized clothing by simply pointing their finger above a sensor.
The researchers show how they placed tiny flexible and highly responsive magnetoresistive sensors within braided textile yarns compatible with conventional textile manufacturing. The garment can be operated by the user across a variety of functions through the use of a ring or glove which would require a miniature magnet. The sensors are seamlessly integrated within the textile, allowing the position of the sensors to be indicated using dyeing or embroidering, acting as touchless controls or ‘buttons’.
The technology, which could even be in the form of a textile-based keyboard, can be integrated into clothing and other textiles and can work underwater and across different weather conditions. Importantly, the researchers argue, it is not prone to accidental activation unlike some capacitive sensors in textiles and textile-based switches. “By integrating the technology into everyday clothing people would be able to interact with computers, smart phones, watches and other smart devices, transforming their clothes into a wearable human-computer interface”, summarizes Dr. Denys Makarov from the Institute of Ion Beam Physics and Materials Research at HZDR.
Washable fashion for human-computer interaction
The technology could be applied to areas such as temperature or safety controls for specialized clothing, gaming, or interactive fashion – such as allowing its users to employ simple gestures to control LEDs or other illuminating devices embedded in the textiles. Furthermore, the research team demonstrates the technology on a variety of uses, including a functional armband allowing navigational control in a virtual reality environment, and a self-monitoring safety strap for a motorcycle helmet. “It is the first time that washable magnetic sensors have been unobtrusively integrated within textiles to be used for human-computer interactions”, emphasizes Prof. Niko Münzenrieder from Free University of Bozen-Bolzano.
“Our design could revolutionize electronic textiles for both specialized and everyday clothing,” said lead researcher Dr. Pasindu Lugoda, who is based in Nottingham Trent University’s Department of Engineering. He further remarks: “Tactile sensors on textiles vary in usefulness as accidental activation occurs when they rub or brush against surfaces. Touchless interaction reduces wear and tear. Importantly, our technology is designed for everyday use. It is machine washable and durable and does not impact the drape, or overall aesthetic appeal of the textile.”
Electronic textiles are becoming increasingly popular with wide-ranging uses, but the fusion of electronic functionality and textile fabrics can be very challenging. Such textiles have evolved and now rely on soft and flexible materials which are robust enough to endure washing and bending, but which are intuitive and reliable.

The Helmholtz-Zentrum Dresden-Rossendorf (HZDR) performs – as an independent German research center – research in the fields of energy, health, and matter. We focus on answering the following questions:
• How can energy and resources be utilized in an efficient, safe, and sustainable way?
• How can malignant tumors be more precisely visualized, characterized, and more effectively treated?
• How do matter and materials behave under the influence of strong fields and in smallest dimensions?
To help answer these research questions, HZDR operates large-scale facilities, which are also used by visiting researchers: the Ion Beam Center, the Dresden High Magnetic Field Laboratory and the ELBE Center for High-Power Radiation Sources.
HZDR is a member of the Helmholtz Association and has six sites (Dresden, Freiberg, Görlitz, Grenoble, Leipzig, Schenefeld near Hamburg) with almost 1,500 members of staff, of whom about 680 are scientists, including 200 Ph.D. candidates.
