At the same time, various hard technologies have also added a touch of tenderness to the opening of the Winter Paralympics

The Mystery of the Torch Housing: Third Generation Polysilazane Resin

"Come on!" At the opening ceremony, the last torchbearer, Li Duan, a visually impaired athlete, boarded the main torch stage of the Beijing Winter Paralympics.
The angle of the torch was wrong and it failed to complete
.
In just one minute, the hearts of the audience gradually became tense with his movements, and they shouted "Come on" for him from time to time

The "Flying" torch of the Winter Paralympics in Li Duan's hands is almost the same as that of the Winter Olympics, with only slight differences in color
.
The torches of the Winter Olympics are made of red and silver, while the colors of the torches of the Winter Paralympics are gold and silver

A "mysterious resin" material is also used in the carbon fiber shell of the "Feiyang" torch, which was independently developed and provided by Kube Chemical (Shanghai) Co.
,
Ltd.
Liu Zhangyou, general manager of the company, said that ordinary resin and carbon fiber composite materials can only withstand temperatures around 200 °C

A new weapon for epidemic prevention and control: plane cavity structure mask

　　To participate in the opening ceremony of the Winter Paralympics under epidemic prevention and control, masks are a "necessity"
.

　　The masks worn by Chinese athletes when they enter the stadium is a medical-grade multi-purpose high-efficiency protective mask independently developed and designed by China
.
In the exterior design, around the theme of "Lights of Ten Thousand Homes", the Beijing Winter Paralympics and various Chinese elements are integrated, implying that the Paralympic athletes are like lights, illuminating the night sky with the spirit of self-improvement

　　It is reported that this mask adopts a unique structure of variable plane-cavity
.
When this structure is worn, the sealing effect is better

　　The blessing of steel suits: exoskeleton wearables

　　The torch relay is an important link before the opening of the Paralympic Winter Games
.
A number of torchbearers dressed in "steel suits" walked with the help of exoskeleton robots and completed the Winter Paralympic torch relay

　　In this torch relay event, Yang Shuting, who was paraplegic due to a car accident and could not walk upright for 11 years, stood up with the help of an exoskeleton robot and successfully completed the torch relay
.
Coincidentally, Zou Haipeng, a high paraplegic patient, also appeared wearing exoskeleton robotic equipment at the starting ceremony of the Beijing Winter Paralympics

　　It is reported that these two exoskeleton wearable devices were developed by the team of Shuaimei, School of Biological and Medical Engineering, Beihang University
.
This kind of equipment is equipped with intelligent sensor network and intelligent control system, relying on multi-joint coordination control center, breaking through key technical links such as intelligent biological perception and bionic walking, human-machine fusion multi-mode hybrid control, etc.
, to assist players to walk upright
.

　　Xu Zhijun, deputy secretary-general of the Beijing Winter Olympics Organizing Committee and director of the torch relay special team of the Beijing Winter Olympics Organizing Committee, said that he hopes to convey the concept of "technology changes life and makes the impossible possible" to people in this way, so as to inspire more disabled people Facing life bravely, not abandoning, not giving up the desire to live independently
