Animated Tattoos
Everyone's going to say "Baked - The Illustrated Man," but here goes… | |
The technology's not quite in place yet, but idea concerns a computer-controlled system whereby a series of images is rapidly rendered on the skin and immediately erased via lasers. Each image is slightly different then the next, the effect being animation.
The latest on tattoos.

Programmable subcutaneous visible implant. (No lasers though. I really don't think the laser part is going to fly.) [jutta, Aug 09 2001]

Maybe Lydia used lasers to get her flag tattoo to wave. [robinism, Oct 05 2004, last modified Oct 21 2004]

Lasers produce heat, to burn away the tattoo pigment. Some of that heat will be transferred to the skin. You'd probably be quite uncomfortable after a very few frames. |
|
| |
As an alternative, I'll shamelessly plug my Electronic Ink Tattoos, on this very site. |
|
| |
Erased via lasers? Where from? |
|
| |
Perhaps a peacetime use for a "Star Wars" missile defense system? |
|
| |
I imagine a subcutaneous nano-laser system sweeping back and forth below the tattooed area, alternating with the apparatus's rendering element. It would alternate between rendering slightly different images and wiping them, kind of like windshield wipers. |
|

"Baked - The Illustrated Man". |
|
| |
I think that if you can have lasers sweeping through the skin N times per second, you should just project the image on the skin using the laser, and ignore the tattoo part. Same visual effect, except it glows! |
|
| |
How many times have you had (what you hope are) laser pens pointed at you while out and about? 5 or 6 for me... |
|
| |
several dozen times, but no big deal. They're all around 2-5 mW, and can't cause any permanent damage. |
|
| |
I think he meant the type of beam where the next thing that happens is you get shot by a high tech gun with one of those laser scope things. |
|
| |
Not sure about the choice of technology, but I like the concept. |
|
| |
Artificial skin is a prerequisite to this. But, LCD membranes are becoming thinner and thinner these days, and eventually you will be able to slap on a patch that looks very much like a Band-Aid, that can have moving pictures on it. |
|
| |
I thought of lasers, imagining they could erase each successive image by burning off a thin layer of skin. I guess before long you wouldn't have much skin left, though, so the artifical stuff makes sense. |
|
| |
If we're assuming nanotechnology, why not just have a bunch of nano-LEDs under the skin? |
|
| |
I never should have said "nano" anything, since that technology is still theoretical. |
|
| |
How about just projecting the images as on the opening title sequences for From Russia with Love, Goldfinger, and Octopussy? |
|
| |
Ya know, they have discovered how to derive power directly from glucose(yes using nano-tec!). So why not use the power to control some LCD material installed in the skin? I'ld hate to consdier wiring such a thing up under the skin! eek! |
|
| |
No, they'd just know how much glucose you have. |
|
| |
Which brings up an interesting use - diabetics. Perhaps a cutaneous LCD or micro-LED display could be devised to show by color or by indicator bar the current level of blood glucose, making it unnecessary to prick oneself multiple times per day... |
|
| |
What was that show... "Quicksilver"? Where the guy's tattoo showed the level of enzyme in his system and he'd die or something if it ran out?... Kinda like that. (Yes, late-night TV...) |
|
| |
Just brainstormin' out loud here... |
|
| |
This is doable. There was once (and maybe still is) a
proposal for electronic paper. It involved small capsules
containing a clear (or maybe white) gel and coloured
particles. An electric field was used to move the coloured
particles to one side of the capsules, so they'd appear
black. Reversing the field would move them to the
opposite side ("inside" the paper) making that area appear
white. |
|
| |
I see no reason why this couldn't be done using very small
(tens of microns) capsules and ferrous particles which
could be moved using a powerful magnet. You could
embed the particles in the skin in much the same way as
normal ink using a tattoo needle, and then write and erase
the images using a magnetic head. |
