Scientists at at Brigham Young University (BYU) in the United States have created an origami-inspired, lightweight bulletproof shield that can protect law enforcement officials from gunfire.
The new barrier can be folded compactly when not in use, making it easier to transport and deploy. When expanded — which takes only five seconds — it can provide cover for officers and stop bullets from several types of handguns.
Current barriers are so heavy and cumbersome they make it difficult for officers to move into position.
The barrier researchers designed is made of 12 layers of bulletproof Kevlar and weighs only 24 kg. T
The barrier uses a Yoshimura origami crease pattern to expand around an officer, providing protection on the side in addition to protecting them in the front.
In testing, the barrier successfully stopped bullets from 9 mm, 0.357 Magnum and 0.44 Magnum pistols.
Since Kevlar fabric is subject to fraying, abrasion and is sensitive to sunlight and water, the team also made a concentrated effort to reinforce it against the environment.
