Digital Condom for electrifying sex
The condom has hardly changed in a hundred years, which is pretty ridiculous if you consider how few people actually like the damn things. A lot of people, in fact, are so unhappy with the timeworn rubber, they eschew using it at all—a problem a couple of researchers out of Georgia Tech think can be solved with electronics.
Fraz Peer and Andrew Quitmeyer created a prototype of an open source, digital condom that's literally wired with electrodes along the side of the sleeve and hooked up to a microcontroller for power. The device creates electrical impulses along the shaft to mimic the pleasurable sensation that is dulled by traditional condoms. It's called, somewhat horrifically, the Electric Eel.
