This might sound nuts but, programmable/shifting tattoos.
Like, it could detect elevated levels of cortisol in your blood or increased heart rate and then just gently pulse or warm up to a comforting temperature as a way calm you down or remind you to breathe. Or light up like a custom RGB keyboard, or change colors/holographic effects depending on time of day. Anything really.
Octopus skin. Neat.
I really want a tattoo but hate commitment so I'm holding out for e-ink tats being invented in my lifetime ๐ค
A tattoo that works like a sign on the forehead that says "warning: grumpy" that lights up accordingly, would be useful for all of society in my opinion.
