NTT, a japanese communications company, has developed a technology called RedTacton that can transmit information around your body at speeds of up to 2Mbps, which is roughly equivalent to a fast broadband connection. it doesn't actually transmit electricity through your body, but rather uses a minute electric field that occurs naturally on the surface of every human body, allowing information to extend out for a distance of about 20 cm from your body. you can then transfer information not only through devices located on or near your skin, but also to other people with a similar device on their body.

some creative uses include exchanging phone numbers or personal information through shaking hands or kissing, trading music files by holding hands, or simply by transferring pictures from a digital camera to your laptop just by touching the two.
