A cut from the article:

Developed by Norman Wagner, a professor of chemical engineering at the University of Delaware's Center for Composite Materials, it's a mix of polyethylene glycol, a polymer found in laxatives and other consumer products, and nanobits of silica, or purified sand. Together they produce a "sheer-thickening liquid" that stiffens instantly into a shield when hit hard by an object. It reverts to its liquid state just as fast when the energy from the projectile dissipates.



And this should help alot too...

Called the Deep Bleeder Acoustic Coagulation (DBAC) program, it aims to create a cuff-like device that wraps around a wounded limb. Rather than applying pressure to the wound to stem the flow of blood, the device would use focused beams of ultrasound (sound waves above the audible frequencies) to non-invasively clot vessels no matter how deep they are.

 

good find. be interesting to see what develops.
