It's pretty well known at this point that computers are quickly catching up with humanity as far as brain power is concerned. Storage-wise, we've been long surpassed by machines, and powerfully fast computers can run circles around the human brain in solving complex equations. On the other hand, humanity wins in the brain's sheer computational power and energy efficiency.

Researchers have found plenty of uses for carbon nanotubes, but a team at Stanford's of the Bao Research Group found a new use for them: artificial skin. The researchers created a stretchable, transparent skin-like sensor that not only is elastic like skin, but can also sense touch and pressure like the real thing.
