Smart shirt that can monitor your heart rate

HOUSTON, Texas: U.S. scientists have invented a shirt using flexible carbon nanofibers that can keep a constant eye on the wearer’s heartbeat.

This “Smart shirt” has been developed in almost two years in collaboration with several American universities under the leadership of experts from Rice University.

According to a report published in the latest issue of the research journal “NanoLetters”, the biggest challenge in making this smart shirt was to make a thread that was as wide as a nanometer, wrapping elastic carbon fibers together. Through which electricity can pass and it can also be used in sewing clothes.

For this purpose, seven carbon fibers, thinner than hair, only 22 micrometers wide, were bundled around each other, and then three such bundles were wrapped together to form a carbon nanofiber thread.

This nanofiber thread was sewn with a shirt in the style of a zigzag pattern. A T-shirt made in this way was worn by a middle-aged volunteer and his heartbeat was monitored continuously for several hours.

Not only can these nanofiber threads conduct electricity, but they are also comfortable and durable that do not deteriorate even when the shirt is washed.

The volunteer wearing the shirt was also satisfied during the experiment and did not experience any discomfort or confusion.

The shirt is made of loose but soft and flexible fabric, while it can record the wearer’s heartbeat for several hours straight.

It should be noted that the “Smart shirt” is currently in the experimental phase with the aim of making its production less expensive and faster so that it can be manufactured on a large scale in the coming years. And possibly replace the smart watch or other devices that are commonly used today to monitor health.
