Tech21 is a manufacturer of mobile accessories specialising in ruggedised, shock-absorbent cases. In the following video, a Tech21 rep gives a demonstration of D30 which is used by military for impact protection on the battlefield -- by laying into his own finger with a hammer.
D30 is an impact protection material made from dilatant non-Newtonian fluid. Its molecules lock together to absorb shock and disperse energy which translates to less damage to whatever/whoever is wearing it. Traditionally used in the military and extreme sports, the material has now made its way to phone cases courtesy of Tech21.
Earlier today, we were given a demo of D30 in its malleable, unfinished state. The plucky demonstrator put his own finger on the line to prove how shock absorptive is is. Check out the video below:
