The new technology is based on fibers made of carbon nanotubes: they are as strong as carbon fiber, and
The authors of the new work have long been interested in the development of smart clothing, but the fibers they wanted to use for this were so thin that they could not be used with a conventional sewing machine.So the team used a rope-making device to tie all the threads together.These bundles were then woven into a fiber that looked like a regular thread.
Such a conductive thread can now be sewn with a sewing machine into ordinary fabric.Moreover, the authors made zigzags during sewing so that the fiber would not break when stretched.Now, the threads sewn onto the jacket have metallic conductivity, like built-in electrodes and wires for transmitting signals.
During the experiment, the team checked howThe new smart shirt records real-time heart rate data. As a result, the recording was successful. The authors also used filaments as electrodes for an electrocardiogram and found that the shirt provided performance comparable to commercially available electrode monitors.
The authors see many potential applications for their technology, in particular in the realm of continuous health monitoring.
