Interesting how carbon nanotubes are getting into everything recently. Reminds me of the early days when laser was beginning to make it's way into practical applications and now it's everywhere.
Although it's an incredible work, the real challenge is to feed the sensory data to the brain. With this artificial skin, it's an engineering problem. You can easily experiment and change your design. When it comes to dealing with the human brain, it's a totally different story.
