.A group of scientists led by Hanyang University Professor Kim Seon-jeong have developed yarn that can produce electricity through contraction and relaxation ― a world first ― according to the Ministry of Science and ICT (MIST), Thursday.
Naming the invention the "twistron yarn," the research team expect it can be used for electronics products such as wearable devices, smartphones and drones that will be able to operate for longer without an additional power supply.
"Unlike batteries, which can provide energy only for a limited time, the twistron yarn can produce renewable electric power unlimitedly and semi-permanently," Kim said.
"We believe it has high potential for diverse industrial applications such as self-operating wireless sensors, mass power production in the ocean and lasting power supply for handsets and drones."
Kim said the ultimate goal is to further improve the efficiency of twistron yarn's power generating capability and to make it mass-producible at a low cost...........
........The research and development of twistron yarn will be released through international scientific journal Science on Friday.
Besides Kim, his colleagues Kim Shi-hyeong at Hanyang University as well as Ray Baughman, Carter Haines and Na Li from University of Texas at Dallas have worked together for this paper titled, "Harvesting electrical energy from carbon nanotube yarn twist," the ministry said.

"... It is only in this way that we can hope to arrive at truth, and fulfill the great responsibility which we hold to God and our country. Should I keep back my opinions at such a time, through fear of giving offense, I should consider myself as guilty of treason towards my country, and of an act of disloyalty toward the Majesty of Heaven, which I revere above all earthly kings."....I know not what course others may take; but as for me, give me liberty or give me death!"
