Looks like you're putting a super thin layer of graphene on the skin, here's a tweet I found from one of the people working on this mentioned in the article.

Thanks. I thought this was a real tattoo which would have been pretty wild

I'm sure parts of the body mod/biohacking community are already working on it. People are already doing things like embedding RFID into their hands.

When I read the headline I thought they had somehow managed to get an actual tattoo to respond to blood pressure changes through the pressure itself, similar to how the cells in Octopi change colour.

my actual tattoo reacts to something (allergens?) occasionally and raises up (I can feel the lines when i touch it).

i can imagine that an electronic tattoo of some sort would feel really strange.

I almost embedded an RFID a few years back but chickened out.

Your tattoo probably is the allergen.

It happens with mine too occasionally, it's more noticeable if I'm hot or if I've not moisturised recently.

What colour is your tattoo? I was hearing that red ink can especially be a source of these kinds of skin problems because of the presence of small amounts of mercury in it [1]

mine is just black its not even shaded

I read that as “I embedded an RFID in a chicken”.

Reminds me I went to a dairy the other week where chipped cows trigger feeding and milking bots for detailed monitoring, dietary microadjustments, etc. I’ll see if there’s info worth posting.

Livestock seems like it would be the place to start with permanent medical data implants, including batteries and a computer.

Got it, sounds like it's a tattoo in the sense of temporary tattoo/skin decal.
