If you find schlepping a Bluetooth enabled earpiece too cumbersome, perhaps it’s time you got a Bluetooth enabled tattoo.
The top surface enables touch-screen control through the skin. Instead of ink, the display uses tiny microscopic spheres, somewhat similar to tattoo ink. A field-sensitive material in the spheres changes their color from clear to black, aligned with the matrix fields.
The tattoo display communicates wirelessly to other Bluetooth devices – both in the outside world and within the same body. Although the device is always on (as long as your blood´s flowing), the display can be turned off and on by pushing a small dot on the skin. When the phone rings, for example, an individual turns the display on, and “the tattoo comes to life as a digital video of the caller,” Mielke explains. When the call ends, the tattoo disappears.
Could such an invasive device have harmful biological effects? Actually, the device could offer health benefits. That´s because it also continually monitors for many blood disorders, alerting the person of a health problem.
