Functional tattoos
I really want to get a UV tattoo that "does something". Started trying to come up with ideas, and decided to start this as a catch-all thread for tattoo ideas that can be functional. What I've come up with so far:
Barcode, QR Code, or other data encoding. Bonus points for encoding a cloud storage URL so you can change what is actually linked while keeping the tattoo the same.
Markers for implants, present or future. Could be a way to indicate where to cut or inject, etc.
Visual aids such as a ruler, protractor, conversion chart, or similar. Can't imagine a way to make it visually appealing, though.
Maybe a UV reactive tattoo over an implanted LED in the right frequency range, to make a self-powered glowing tattoo? Could be a way to get more out of an implant like Circadia.
Anybody else have ideas for functional ink?

The scanners which use lasers, like a grocery store scanner, use very low power, <5mW, lasers. They will not damage skin or tattoos if they have not been tampered with.

conductive inks work fine when painted onto skin. I still have to see someone inventing a tattoo ink that conducts electricity without making electrical contact to your body (aka electrocuting yourself)

Also if anybody wants to try one of VivaINK's new digital tattoos with their Moto X phone, I have a few spares.

I'd love to get one, let me know cost + shipping to .au
The cathode is platinum, which (currently) costs $1460 per oz. The output is 70µW per cm2. I'm pretty sure that this would get pretty expensive, pretty fast! What can run on 70-210µW?
Or, rather than sweat, could you replace some of your gut flora with a species that produces lactic acid? Thinking about it, that's a terrible idea...
