Researchers at the University of Waterloo in Canada have developed an innovative smart fabric based on MXene and conductive polymers that can efficiently convert body heat and solar energy into electricity. This breakthrough fabric offers a significant advancement in wearable technology by eliminating the need for external power sources or frequent recharging.
MXene, a newly-developed graphene-like two-dimensional transition metal carbon compound, is key to this fabric’s functionality. It is produced by selectively etching specific atomic layers from layered nitrogen compounds, resulting in a highly conductive material with unique properties. “We have developed a fabric with multi-functional sensing capabilities and self-powering potential,” explains Professor Yuning Li, director of Waterloo’s Printable Electronic Materials Lab. “This innovation brings us closer to practical applications for smart fabrics.”
The smart fabric is more stable, durable, and cost-effective than existing options, setting it apart from current wearable devices. It integrates various sensors capable of monitoring temperature, stress, chemical composition, and more, with a promising application in smart face masks. These masks could track breath temperature and rate, and even detect chemicals in the breath to help identify viruses, lung cancer, and other conditions.
The research team plans to enhance the fabric’s performance in the next phase while collaborating with electrical and computer engineers to integrate electronic components. Future developments will include a smartphone app to track and transmit data from the fabric to healthcare professionals, enabling real-time, non-invasive health monitoring for everyday use.
