Electric Tattoo

Let's face it - the only reason anyone ever reads Scientific American is to see how "shiny" the future is going to be.

Electric Tattoo

The basis of the 2x4-inch "Digital Tattoo Interface" is a Bluetooth device made of thin, flexible silicon and silicone. It´s inserted through a small incision as a tightly rolled tube, and then it unfurls beneath the skin to align between skin and muscle. Through the same incision, two small tubes on the device are attached to an artery and a vein to allow the blood to flow to a coin-sized blood fuel cell that converts glucose and oxygen to electricity. After blood flows in from the artery to the fuel cell, it flows out again through the vein.

On both the top and bottom surfaces of the display is a matching matrix of field-producing pixels. The top surface also 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.

The tattoo display is still just a concept, with no word on plans for commercialization.


So... is it bad that I really want something like this?

wow *in awe* that's really amazing how it can use just oxygen and glucose to create a little energy source! O_O
it's basically doing exactly what the cellular mitochondria does! I wonder how they made it work...

I don't know if I'm really keen on having things unfurl "beneath the skin to align between skin and muscle", that sounds kinda uncomfortable to me. I also kind of wonder how bright that little screen is, since below every layer of skin is kind of thick... that might be a complication?

Sounds really neat though!

Well, I imagine that during the installation you'd be under at least a local anesthetic, so it probably wouldn't be uncomfortable at all. Or even felt.

As for the brightness... it's not at all. Take a look.

It's basically like a little liquid crystal display, normally invisible but sometimes making your skin darker in patches. It'd probably be more useful to have it on the back of the arm than the back of the hand... easier to not mess something up, as the hand is a bit more complicated.

oooooh... looks interesting, it's bigger than I thought it'd be though.
thanks for the pic!
