CTOnews.com, July 26 (Xinhua) Rugby is a traditional American sport that can easily lead to injuries and "concussions for millions of people every year." To solve this problem, researchers at Stanford University worked with Savior Brain to create an ergonomic helmet with a liquid shock absorber that reduces the impact on the head by 1/3 compared to a traditional rugby helmet.

According to the New York Post, the researchers collected helmet data that fit most people's heads by measuring the head data of volunteers, and built a finite element model with 21 liquid shock absorbers installed in the model for researchers to quantify the role that liquid shock absorbers can play when the human head is hit violently.

"most of our team members are particularly fond of rugby and have suffered a lot of injuries, so our team is very concerned about 'how to ensure the long-term health of athletes' and avoid the risk of concussion, and our helmet technology can play an important role in reducing the risk of brain damage," said Nicholas Cecchi from the blog research team at Stanford University.

The researchers measured the head kinematics data of each impact by measuring the head kinematics data of each impact. (CTOnews.com Note: rugby helmet requires safety certification, which is a common standard in the industry and can only be sold after passing the evaluation protocol. The head acceleration response index (HARM) score is obtained, which is used to evaluate the performance of the helmet under impact.

The results show that the ergonomic helmet can significantly reduce the impact force on the head. Among the 36 different impact test conditions, 33 have the lowest HARM, which can be reduced by up to 1/3 compared with the existing products on the market.

The research team now plans to continue to refine the helmet prototype, and they also plan to use 3D printing to mass-produce the first batch of helmets for testing in real-world conditions.

"in the future, we are also interested in conducting human research to prove that the helmet does protect the health of athletes in real life, and we plan to expand the application of liquid shock absorbers to more scenes to further improve the safety of all groups of people," Nicholas Cecchi said.
