Burning ice and snow to spell out the future ｜ University research team develops ＂warm suit＂ to serve winter Olympic athletes with intelligent warm technology.

　　CCTV News:As the key project of "Science and Technology Winter Olympics" and "Key Technology of High-performance Clothing Research and Development in Winter Sports and Training Competition", the research team from universities has developed gloves and headgear that can realize intelligent temperature control, providing more comfortable warm-keeping experience for athletes and coaches.

　　Since October 2019, tianjin polytechnic university Institute of Textile Science and Engineering has set up a research and development team to design and develop headgear and gloves that can keep warm by electric heating for China athletes and coaches participating in the Winter Olympics. In the past two days, the garment technology room of the college has been temporarily transformed into a "production workshop". After more than two years of continuous optimization, the first batch of 200 pairs of gloves and 200 pairs of headgear will be completed soon. After the heat preservation test, pressing and packaging, it will be delivered to the major stadiums in Chongli, Zhangjiakou in two batches on December 10th and 25th this year, and provided to China athletes participating in the 2022 Winter Olympics. Next, the team will continue to supply this technological "warm suit" according to the dynamic needs of the Winter Olympics Organizing Committee.

　　According to reports, at present, the temperature control protective gear on the market is generally in the middle, high and low grades, with 10℃ as a unit, which has a large adjustment range and is easy to change from "too cold" to "too hot" at once, greatly reducing the comfort of the wearer, thus affecting the physical state of athletes. Therefore, tianjin polytechnic university team developed this system which can realize accurate temperature control by using technology empowerment.

　　Experts said that at present, the ice and snow sports headgear and gloves on the market are becoming thinner and thinner, and adding this intelligent temperature control system which includes a heating plate and a temperature control module will, in theory, significantly increase the load of the equipment itself. To this end, the team has changed and adjusted the design scheme five times. On the premise of ensuring the heating effect, it has developed lighter electronic components, fabrics and thermal cotton to reduce the overall weight and enhance the wearing experience.

　　At present, the team is still stepping up the research and development of an intelligent temperature control system that can sense the wearer’s body temperature. After it is put into application, it can automatically adjust to the most comfortable temperature without the active control of the wearer. This will not only provide more scientific pre-competition guarantee for China athletes participating in the Winter Olympics, but also provide warmth for the vast number of ice and snow sports enthusiasts, and encourage more people to walk on the ice and enjoy the fun of ice and snow.
