ENERGY-CREATING YARN COULD BE USED IN 'SMART CLOTHING'

This yarn charges when twisted.

 

Although constant threats of an energy crisis fill the news these days, there’s also a ton of different research groups looking to develop innovative ways for us to generate electricity. The latest development is a yarn made from nanotubes that generates electricity when it is twisted or stretched.

  에너지 위기의 지속적인 위협이 요즘 뉴스를 장식하고 있지만, 우리가 전기를 생산할 수 있는 혁신적인 방법을 개발하고자 하는 수많은 다른 연구 그룹들도 있다. 최근 개발은 나노튜브로 만든 실을 꼬거나 늘어나면 전기를 발생시키는 기술이다

 

사이언스 최신호에 발표된 새로운 결과에서, 국제 연구 단체는 인간의 머리카락보다 지름이 10,000배 작은 이 새로운 "트위스트론" 실이 어떻게 사물의 인터넷을 작동시키는 새로운 방법을 안내할 수 있는지, 모티로 물을 생성하도록 기술을 확장할 수 있는지를 보여준다.(해양이나 기온의 급격한 변화에서도)

 

 

달라스 텍사스 대학의 엔지니어이자 이 새로운 연구의 공동 저자인 카터 헤인즈는 15년간의 연구 끝에 얼마나 획기적인 발전을 이루었는지 설명하는데, 이 연구에서 에너지를 모으는 경량 소재를 만들기 위한 "연구실에서의 이전의 모든 시도"는 "실제로 그렇게 잘 작동하지는 않았다"고 말했다.

In new results published in the latest issue of Science, an international group of researchers demonstrates how this new “twistron” yarn — 10,000 times smaller in diameter than a human hair — could perhaps usher in a new way of making internet of things devices run, as well as potentially scaling up the technology to generate water through the motion of the ocean or rapid changes in temperatures.

 

 

Carter Haines, an engineer at the University of Texas at Dallas and a co-author of the new study, describes how the breakthrough was after 15 years of work, in which “all our previous attempts in the lab” to create an energy-harvesting lightweight material “really didn’t work that well.”

The twistron, which can be twisted up “like sheep’s wool,” says Haines, “is something we’ve been wanting to do for a while, but we finally stumbled on a solution that works.”

 

Dr. Carter Haines, Dr. Shi Hyeong Kim, and Dr. Nai Li of UT Dallas are lead authors of a study that describes carbon nanotube yarns that generate electricity when they are stretched or twisted.University of Texas-Dallas

 

The new material works by essentially generating electricity out of mechanical energy — which in this case is basically the stretching of the yarn. The carbon nanotube yarns are coated with an electrolyte material (like table salt and water) which charges the yarn up when it’s twisted or stretched. That voltage, then stored in the yarn, harvests electricity.

 

Stretching a twistron yarn 30 times will produce about 250 watts per kilogram of peak electrical power. That’s about one-third of a single horsepower or “about four old-school bulbs working at the same time,” Haines tells Inverse.
