South Korea and the US invent carbon fiber that can produce electricity

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

This advanced technology promises the development of smartphones and other electrical devices that do not require batteries in the future.

The study was conducted by a group of scientists from Hanyang University in Korea and the University of Texas in the US and published in the journal Science on August 24.

According to research, the material is made from carbon nanotubes consisting of cylindrical carbon molecules with a diameter 10,000 times smaller than a human hair.

The fibers are charged by being immersed in an electrolyte or simply a solution of salt and water. When stretched or twisted, the fibers generate electricity. Experiments have shown that a single strand of the material, “weaker than a fly,” can light up a small LED.

The study authors say the material has potential applications for harvesting energy from the movement of ocean waves or even temperature fluctuations, potentially creating a continuous power source for mobile phones or drones in the not-too-distant future.
