Dr. Carter Haynes of the University of Texas in the United States said in an interview with a Sino-foreign cooperative research published in the journal Science: "A stretched yarn can produce electricity and sew on clothes. do not add power, it can produce an electrical signal normal breathing.

Many of the carbon nanotube spun yarns are referred to as Twistron. The diameter of a single carbon nanotube is 10,000 times smaller than the diameter of a human hair. In order to form a spring-like structure with high elasticity, the researchers are constantly improving the twist.

"These yarns are essentially a supercapacitor, but it doesn't require an external power source to charge," Dr. Li Na of the Nano Research Institute told the Science and Technology Daily. Because the carbon nanotubes differ from the chemical potential of the electrolyte, a portion of the charge is embedded when the yarn is immersed in the electrolyte. When the yarn is stretched, the volume is reduced, the charges are brought closer to each other, and the voltage generated by the electric charge is increased to obtain electric energy.

“When stretching at a frequency of 30 times per second, the yarn can produce a peak electric power of 250 watts/kg. A yarn that weighs less than the fly can illuminate an LED each time it is stretched.” Nano Research According to Dr. Bowman, one of the directors and author of the article, the power per unit weight of Twistron yarns can be increased by more than 100 times compared to other woven power fibers.

Bowman said: brine can also be used as an electrolyte. The output of the yarn can be scaled up as the yarn volume increases and the number of yarns working in parallel increases. “If you reduce production costs, Twistron can eventually be used for wave power generation.”

The most suitable application for carbon nanotube yarns today is to power sensors or IoT communications. “Based on our average output power, we only need 31 milligrams of yarn to transmit 2 kilobytes of data packets every 10 seconds for the Internet of Things within a radius of 100 meters.”
