Engineering professors at Brigham Young University have designed a new bulletproof shield for law enforcement that can withstand shots fired from 9mm, .357 Magnum, and .44 Magnum pistols. The key difference between this shield and others is its low weight — 55 pounds — and its folding mechanism, which takes a cue from origami. The shield’s made of 12 layers of bulletproof Kevlar with an aluminum core in the middle.

The engineers say that many bulletproof barriers are made of steel and weigh nearly 100 pounds. These might not be as convenient as their solution, but of course, different shields can stop different types of bullets, including from rifles. Still, Brigham Young’s team thinks their shield might be good for police to carry in their car when responding to crime scenes, especially because it can protect multiple people when deployed. No law enforcement agencies are currently using the shield as it’s still being prototyped.
