The researchers said the “smart fabric” could be enhanced in functionality when combined with sensors, so it could be used to monitor heart rate, temperature, and even detect chemicals in breath.
The study explained that the research team succeeded in combining advanced materials, such as MXene and conductive polymers, which are known for their high electrical conductivity and flexibility, with advanced textile production methods.
The team created a surface that attracts MXene molecules via hydrogen bonds, resulting in a stretchable thermoelectric fabric.
“We have developed a fabric material with multi-functional sensing capabilities and self-powering capabilities,” said Yuning Li, professor in the Department of Chemical Engineering. “This innovation brings us closer to practical applications of smart fabrics.”
Most wearable electronics today require “external power or regular recharging,” but this innovative fabric eliminates the need for batteries entirely.
The researchers say the new fabric is more stable, durable and cost-effective than existing options on the market.
“Printed sensors, including those embedded in smart fabrics, are ideal for continuous data collection and monitoring,” he told me. “This new smart fabric is a step forward in making these applications practical.”
The team revealed that when the “smart fabric” is integrated into a mask, it converts body heat into electricity using the temperature difference between the body and the environment, allowing for precise monitoring of the respiratory rate, while detecting chemical indicators of viruses and other diseases.
The study also reported that “the exceptional strain sensing capabilities of the MXene-based thermoelectric fabric facilitate monitoring the condition of body joints through their deformation.”
The team plans to improve the fabric’s performance and integrate it with electronic components, as well as plans to create a smartphone app that would collect and transmit health data directly to healthcare providers.
The results were published in the journal Materials Science and Technology.
