Polish scientists have developed a liquid (Shear-Thickening Fluid or STF) bulletproof vest, which hardens on impact, protecting the body from bullets.
The liquid is placed in special bags that are worn inside the vest to protect the body while allowing movement comfort.
When the vest is hit by a bullet, the liquid absorbs the force released and prevents any damage in his organs body.
The idea of developing a bulletproof vest is based on the use of a non-Newtonian fluid. These fluids behave in an excellent way as they change their flow depending on temperature or pressure.
Scientists used a non-Newtonian fluid, which is called STF (Shear-Thickening Fluid). Non-Newtonian fluid simply means that it does not follow the rules of Newtonian fluids, for example it does not behave like water. STF hardens upon impact with objects or any change in temperature, thereby providing protection against puncture by high-velocity projectiles speeds.
The exact components of STF have not been announced by scientists, probably because Moratex, the project manager, does not agree.
"We had to find, and design a liquid that stops missiles at a speed of 450 meters per second or even higher. "We did it," Moratex's Marcin Struszczyk told Reuters.
