The new fabric developed by a Waterloo research team in Canada can convert body heat and solar energy into electricity, potentially enabling continuous operation with no need for an external power source. Different sensors monitoring temperature, stress, and more can be integrated into the material.
It can detect temperature changes and a range of other sensors to monitor variables including pressure and chemical composition. According to the team, one promising application is a smart face masks that can track breath temperature and rate and detect chemicals in breath to help identify viruses, lung cancer, and other conditions.
“We have developed a fabric material with multifunctional sensing capabilities and self-powering potential,” Yuning Li, a professor in the Department of Chemical Engineering, said in a statement. “This innovation brings us closer to practical applications for smart fabrics.”

Unlike current wearable devices that often depend on external power sources or frequent recharging, this research has created a novel fabric which is claimed to be more stable, durable, and cost-effective than other fabrics on the market.
This research, conducted in collaboration with Professor Chaoxia Wang and PhD student Jun Peng from the College of Textile Science and Engineering at Jiangnan University, showcases the potential of integrating advanced materials such as MXene and conductive polymers with advanced textile technologies to advance smart fabrics for wearable technology.
“AI technology is evolving rapidly, offering sophisticated signal analysis for health monitoring, food and pharmaceutical storage, environmental monitoring, and more. However, this progress relies on extensive data collection, which conventional sensors, often bulky, heavy, and costly, cannot meet,” said Li. “Printed sensors, including those embedded in smart fabrics, are ideal for continuous data collection and monitoring. This new smart fabric is a step forward in making these applications practical.”
The next phase of research will focus on further enhancing the fabric’s performance and integrating it with electronic components in collaboration with electrical and computer engineers. Future developments could include a smartphone app to track and transmit data from the fabric to healthcare professionals, enabling real-time, non-invasive health monitoring.
The team’s findings are detailed in the Journal of Materials Science & Technology.
