Very intresting concept, imagine answering your mobile phone by pressing an area of your skin, its not a sci-fi movie scene but one of the entries in the Greener Gadgets Design Competition.

The Digital Tattoo Interface works via a Bluetooth device implanted underneath your skin. Don’t worry, you won’t have anything bulging out like a weird growth – the chip is flat, flexible and made of silicone. It lies between your skin and muscle tissue.
Intrestingly this device electricity powers up by bilogical components of the body “convert’s the blood’s glucose and oxygen from the artery as electricity required”.

This device communicates wirelessly with the world as well as with other devices implanted in the same body. It is always present, always on, but out of sight and non-obtrusive. It also continually monitors for many blood disorders, alerting the person of a health problem: A human version of the check engine light. Product styling is the latest and coolest downloaded display interface showing on any tattoo on the block. This product is waterproof too!!.

Great ideas 🙂
