The Chinese made a cardboard bike helmet that protects the head as well as the traditional one
Researchers have developed and successfully tested a new bicycle helmet that uses honeycomb and corrugated cardboard instead of polymer foam.
Nowadays, bicycle helmets are usually made from expanded polystyrene, but due to environmental pollution, scientists around the world are trying to replace common plastic with recyclable materials.
Crash tests conducted by a team at the Center for Injury Biomechanics and Vehicle Safety at Tianjin University of Science and Technology have shown that, when properly designed, a bicycle helmet made only of cardboard can reduce the likelihood of head injury by 63% and loss of consciousness by 86% at any the form of an accident. It is able to effectively withstand external shocks in a short period of time and has good shock-absorbing characteristics..
Such a helmet has not only a low production cost, but is also made of environmentally friendly material..
We also previously reported on the development of a new security application that warns a pedestrian wearing headphones about an approaching vehicle within a radius of 60 m.
