BYU (brigham young university) engineering professors have designed a lightweight origami-inspired bulletproof shield that can protect law enforcement officers from gunfire. based upon a yoshimura origami crease pattern, the barrier can be assembled in just five seconds and folded compactly when not in use, making it easier to transport and deploy. at only 55 lb (25 kg) the barrier is almost half the weight of current steel-based shields and can safely protect two to three people at once. In testing, the barrier exceeded researchers expectations by successfully stopping bullets from 9 mm, .357 magnum and .44 magnum pistols. in addition to protecting police officers, researchers believe the barrier could be used to protect children in a school or a wounded person in an emergency situation. There are a lot of risks to law personnel and we feel like this particular product can really make a difference and save a lot of lives.
