Korea and the United States invented carbon fiber that can produce electricity

A group of Korean and American scientists have invented a new type of carbon fiber that can generate electricity when stretched or twisted.

This advanced technology promises the development of smart phones and other electrical devices without the need to use batteries in the future.

The study was conducted by a team of scientists from South Korea's Hanyang University and the University of Texas in the United States and published in the August 24 issue of Science.

According to the study, the material is made up of carbon nanotubes consisting of cylindrical carbon molecules that are 10,000 times smaller in diameter than human hair.

These fibers are electrically charged by immersion in electrolyte or simply saline solution and normal water. When stretching or twisting, these fibers produce electricity. The experiment showed that a "lighter than a fly" material could light a small LED.

The authors say the material has the potential to be used to capture energy from ocean waves or even temperature fluctuations, thereby creating a continuous power source for mobile phones or computers. drone in the near future.
