Skinput blends the 'real' from the 'unbelievable'
A Microsoft Research project, dubbed Skinput, is exactly that: an input device for the skin. It uses bio-acoustic sensing to determine finger taps on the skin, which is projected from a small pico-projector. The technology has been demonstrated in public numerous times, but is not expected to become commercially viable for the next few years.
Some wearable technologies get a little closer to the skin, though
Electronic tattoos could revolutionize the way we interact with technology and other devices as they can be applied directly to the skin. While still in early development, they could be used in medical situations such as EEGs and EMGs.

While some embed gadgets directly into the body
From wrist watches to eyeglasses and fitness bands, now teeth? One prototype tracker embeds on a molar tooth to detect oral activities, and can relay back health-based information. Over time, as electronics become more connected with Wi-Fi and Bluetooth technology, it's hoped that they can transmit data locally to smartphones and tablets.
