So far, the researchers at the University of Illinois at Urbana-Champaign have managed to create a set of "smart fingertips" that can send electrical signals to the skin. It's basically a tiny little condom made of a circuit-polyimide structure, which is fitted onto a finger-shaped tube of silicon and then your actual finger. The applications for this are numerous, from highly precise surgery to contact sports. Or porn, did we mention porn?
Not only can this thing theoretically transmit different sensations like hot or cold, but the article also mentions that it "could restore sensation to people who have lost their natural skin," like burn victims or amputees. Does that mean they could help disabled people actually feel their prosthetic limbs? Because that would be amazing.

Your missing arm will still itch, but now your replacement will, too!
But imagine a future where you can't just browse the Internet, but actually touch it. Imagine scrolling down your Tumblr feed and being able to feel the fur of that LOLcat, or Tom Hiddleston's face, or Tom Hiddleston's face again. For once, all that baffling talk of "feels" would be justified. Just make sure you take off your electronic glove before you go into 4chan or you could end up touching someone's virtual turd.
