Scientists have developed a groundbreaking type of smart fabric that can be used to control electronic devices without touch.
This new technology, created by researchers from Nottingham Trent University (UK), Helmholtz-Zentrum Dresden-Rossendorf (Germany), and Free University of Bozen-Bolzano (Italy), is the first of its kind to be both washable and durable.
The secret behind this innovation is tiny, flexible “magnetoresistive” sensors that can be woven into fabric.
These sensors respond to magnetic fields, allowing users to interact with the fabric simply by wearing a small magnet, such as a ring or glove.
This means that people could control devices like smartphones, smartwatches, or even gaming systems just by moving their hands near their clothing.
Unlike traditional touch-sensitive fabrics, which can be accidentally activated by rubbing against surfaces, this new technology is more reliable. The sensors only respond to magnetic signals, reducing unwanted interactions.
Because the sensors are built directly into the fabric, they do not affect how the clothing looks or feels. Importantly, they are also machine-washable and long-lasting, making them practical for everyday use.
In their research, the team demonstrated several possible applications for this smart textile. For example, they created a fabric wristband that allows users to control virtual reality (VR) navigation and a self-monitoring strap for motorcycle helmets.
They also suggested that the technology could be used for interactive fashion, gaming, or even safety features in specialized clothing. Imagine being able to turn on LED lights embedded in your jacket just by moving your hand!
Dr. Pasindu Lugoda, the lead researcher from Nottingham Trent University, explained that this innovation could change the future of electronic textiles.
“Touch-sensitive fabrics can be unreliable because they can activate accidentally when brushed against other surfaces. Our touchless design avoids that problem and is also durable enough for everyday wear and washing.”
Dr. Theo Hughes-Riley, another researcher on the project, highlighted the challenge of merging electronics with fabric. “Smart textiles are becoming more popular, but integrating electronic functions into clothing is difficult.
Our design is a step forward because it is flexible, reliable, and able to withstand washing.”
The researchers believe this technology could lead to exciting new possibilities, from interactive fashion to hands-free device control. With further development, we may soon be wearing clothes that double as computer interfaces, making technology more seamless and integrated into daily life.
