Canadian scientists have recently developed smart fabrics, which can convert body heat and solar energy into electrical energy. Electronic devices can operate without being connected to a power source. They can be integrated with wearable devices that monitor temperature, mechanical force, etc. to provide a steady stream of electricity. . The paper was published in the Journal of Materials Science & Technology.
This research was jointly developed by scientists from the University of Waterloo in Canada and the School of Textile Science and Engineering of Jiangnan University in China. It successfully combined advanced materials such as novel two-dimensional nanomaterial "MXene" and conductive polymers through Combining cutting-edge technologies, we launch smart textile materials that can be used to power wearable devices. Existing wearable devices usually rely on external power sources and require frequent charging. Breakthrough innovative materials not only have the opportunity to flip limits, but are also more stable, durable and cost-effective than other fabrics.
Mycoene is a new two-dimensional nanomaterial with great potential after graphene. It is composed of conductive two-dimensional carbides, nitrides and carbonitrides. Successfully developed by Drexel University in the United States in 2011, it is composed of transition metals (titanium or vanadium) and carbon or nitrogen compounds. It has a structure similar to graphene and has high conductivity, high electromagnetic barrier properties, high electrostatic capacity and hydrophilicity. sex. Widely used in electronic devices, energy storage equipment, sensors and biosensors, water purification, etc.
One promising application for smart textiles is smart face masks, which can monitor breathing temperature and rate and detect respiratory chemistry, viruses, lung cancer or other diseases. Another possible application is a heating jacket that converts sunlight into electricity. Wearing this jacket for a walk in the cold winter not only keeps you warm but also provides continuous heating. It is also possible to produce a shirt that uses body temperature to power the heart rate and body temperature. These imaginations may all come true in the near future.
Dr. Yuning Li (transliteration), professor in the Department of Chemical Engineering at the University of Waterloo and lead author, said: "We have developed textile materials with multi-functional sensing capabilities and independent power supply, which are closer to the practical application of smart fabrics."
Artificial intelligence is developing rapidly, and a large amount of data can be obtained to train AI models by continuously monitoring health, food and medicine storage, environmental quality, etc. However, in order to meet the needs of data collection, traditional bulky sensors are difficult to carry around. Wearable devices combined with smart textiles are obviously more conducive to the development of AI.
Printed sensors are thin, flexible and have the potential to be integrated into smart textiles, making them ideal for continuous data collection and monitoring. The next phase of the University of Waterloo team's research will focus on improving fabric performance and working with electronics and information engineers to develop smart fabrics that integrate sensing elements. Products include smart sensing clothing that is connected to a smartphone, which can track the user's body temperature, pulse, etc., and then transmit it to medical personnel via the mobile phone for real-time non-invasive health monitoring.
