Led by researchers at the University of Delaware and at the U.S. Army Research Lab, a new “liquid armor” is being developed to protect against life-threatening injuries. The liquid is made up of a mixture of hard nanoparticles that flows under normal conditions, but stiffens and behaves like a solid under impact. The impact causes the nanoparticles to form tiny clusters inside to fluid to prevent things from penetrating through the armor. By treating fabrics with this liquid, a body armor could be developed to prevent bullets, knife stabs, or shrapnel from harming the body. There are also a number of civilian applications, such as protection against car crashes or making tires sturdier.
