The material can be used to monitor health and track activity.
Researchers from the University of Waterloo and Jiangnan University have developed a smart fabric that collects solar energy and heat bodies and turns them into electricity. It can be used to collect indicators of health and activity.
Scientists have combined advanced materials such as MXene and conductive polymers with textile manufacturing technologies. MXene and conductive polymers – these are materials known for their high electrical conductivity and flexibility.
The engineers applied a sticky layer of polydopamine (PDA) to a nylon fabric and obtained a surface that attracts MXene particles through hydrogen bonds. This combined structure results in an elastic thermoelectric fabric.
Most modern portable electronic devices require external power or regular recharging, but the new fabric completely eliminates the need for batteries. Tests have shown that it is more stable, durable and economical than the options available on the market.
Various sensors can be integrated into the material to change temperature, pressure control, chemical composition and other properties. Engineers are proposing to create smart face masks that will monitor temperature and breathing rate, as well as detect chemicals in the breath, helping to detect viruses, lung cancer and other conditions.
