Washable Smart Textiles With Magnetic Sensors

Clothes that can control devices? Scientists have made smart fabric with hidden sensors, working with a simple magnet. No touch needed!

Researchers from Nottingham Trent University, Helmholtz-Zentrum Dresden-Rossendorf, and Free University of Bozen-Bolzano have developed washable, durable electronic textiles that can sense magnetic fields. Believed to be the first of their kind, these textiles could revolutionize their use in clothing.

Users can interact with the textile using a ring or glove containing a small magnet. The sensors, seamlessly embedded, can be marked with dye or embroidery to function as touchless controls or “buttons.” This technology, which could even enable textile-based keyboards, can be incorporated into clothing and other fabrics, functioning reliably underwater and in various weather conditions.

The researchers emphasize that, unlike some capacitive sensors in textiles, this technology is resistant to accidental activation. By integrating it into everyday clothing, users could interact with computers, smartphones, watches, and other smart devices, turning their clothes into wearable human-computer interfaces.

Potential applications include temperature or safety controls in specialized clothing, gaming, and interactive fashion—allowing users to control LEDs or other embedded lighting with simple gestures. The study showcased the technology in various applications, including a functional armband for navigation in virtual reality and a self-monitoring safety strap for a motorcycle helmet.

This is believed to be the first time washable magnetic sensors have been seamlessly embedded in textiles for human-computer interaction. The researchers believe this design could transform electronic textiles for both specialized and everyday clothing.

Unlike traditional tactile sensors, which can activate accidentally when brushed against surfaces, this touchless technology reduces wear and tear. It is machine-washable, durable, and does not affect the fabric’s drape or appearance, making it suitable for daily use.

Integrating electronics into textiles presents challenges, but advancements in soft, flexible, and robust materials now allow electronic textiles to withstand washing and bending while remaining intuitive and reliable.

This approach opens new possibilities for interactive wearables, including applications in environments where such technology was previously impractical.
