What is this weird D3O® material?
D3O® is a smart, shock absorbing dilatant material which flows freely as a liquid in its raw state. Under the force of impact, the molecules lock together, allowing the material to absorb and dissipate damaging energy.
The impact energy is spread throughout the D3O® composition which reduces the force transmitted to your device. The material then returns back to its original, soft and flexible state. It's strain-rate sensitive; the harder the force of impact the material receives, the more molecules lock together to absorb the energy and protect the technology from damaging drops and falls.
A company Tech 21 makes protective cases out of the crazy goo.
I wonder, maybe we could use this for making football helmets? That would mean less concussions ;)
