"This Bluetooth device is permanently implanted beneath the skin," says the project Website. "It is flat, flexible, silicon, and silicone. Tightly rolled when it's inserted through a small incision, and then unfurled beneath the skin, it lies benignly between skin and muscle."
How would it work? The Website has this to say:
Her cell phone is ringing, but the display is turned off. She lightly pushes a small dot on the skin on her left forearm to suddenly reveal a two by four inch tattoo with the image of the cell phone's digital display, directly in the skin of her arm. She answers the call by pushing a tattooed button on her arm. While she's talking, the tattoo comes to life as a digital video of the caller. When she finishes, the tattoo disappears.
But seriously folks, sci-fi as it may seem, this is only one of several wireless implant projects Unstrung has heard about -- from "tooth phones" to GPS trackers in the digestive tracts of cows. [Ed note: You wish we were making this up!] (See Rinse, Spit, and Call and Cow-Fi, Anyone?)
