The soldier of the future is going to look like Robocop and be just as formidable according to this article. Some excerpts:
"What we hope to gain from this program is body armor that wears like a traditional textile impregnated with nanomachines connected to an onboard computer, DeGay explained. "So when you shoot a round into the uniform system, it's normally pliable until it senses the strike of a round -- it becomes rigid, defeats the strike of the round and becomes soft again."
A shortcoming of traditional body armor is that it can only absorb so many strikes from machine-gun rounds. "When you have a uniform with this new nanotechnology, it can absorb unlimited numbers of machine-gun rounds," DeGay pointed out.
Another potential development is inserting "nanomuscle fibers" that can actually simulate muscles, giving soldiers more strength. Fabric is impregnated with nanomachines that create the same weight, lift and feel as a muscle. "So I coat the outside of the armor with a nanomuscle fiber that gives me 25 to 35 percent better lifting capability," DeGay explained.
The uniform from the waist down will have a robotic-powered system that is connected directly to the soldier. This system could use pistons to actually replicate the lower body, giving the soldier "upwards of about 300 percent greater lifting and load-carriage capability," DeGay said. "We are looking at potentially mounting a weapon directly to the uniform system and now the soldier becomes a walking gun platform."
I guess this is a good thing. See the article for pictures.
