Artificial intelligence (AI) is evolving rapidly, offering sophisticated signal analysis for health monitoring, yet it depends heavily on vast data collection that traditional sensors—often bulky, heavy, and expensive—struggle to provide. Printed sensors, particularly those integrated into smart fabrics, are increasingly recognized for their continuous data collection capabilities. In a significant development, researchers have now created a new smart fabric designed to make such applications more feasible.

Researchers at the University of Waterloo (Waterloo, Canada) have created a smart fabric with remarkable capabilities that could find potential in health monitoring and movement tracking. This fabric, unlike conventional wearable technology that relies on external power supplies or needs frequent recharging, boasts improved stability, durability, and cost-effectiveness. It is capable of converting body heat and solar energy into electricity, thus supporting continuous operation without external power. The fabric can incorporate various sensors to monitor temperature, stress, and more, according to the research published in the Journal of Materials Science & Technology. It is sensitive to temperature fluctuations and can be equipped to gauge pressure, chemical composition, and other parameters.

One particularly innovative application of the smart fabric that is being explored is smart face masks, which could monitor breath temperature and rate, and even detect chemical signatures that may indicate viral infections, lung cancer, or other health conditions. The research team is planning to enhance the fabric's functionality and integrate it with electronic systems, in partnership with electrical and computer engineers. Looking ahead, they aim to develop a smartphone app that would transmit data from the fabric directly to healthcare providers, facilitating real-time, non-invasive health monitoring for daily use.

“We have developed a fabric material with multifunctional sensing capabilities and self-powering potential,” said Yuning Li, a professor in the University of Waterloo’s Department of Chemical Engineering. “This innovation brings us closer to practical applications for smart fabrics.”
