Yeah this is a cool idea. When I watched the vid I starting thinking about what kind of "cool future stuff" these batteries could be applied to. This lead me to remember the cool "animated fingernails" the character Luv had in the Blade Runner sequel. Notice her thumbnail in particular - she has like a funny little Pokémon-type character on it:

I'll bet with tiny little diamond batteries someone could figure out how to create LED based fingernail decorations like that. ;)

Hmmm, the nails even look kinda thick ;)

Yeah I'd assume that anything like these animated nails IRL would likely be artificial "press-on" nails that would contain all the super-thin electronics and batteries. The idea that someone would "tattoo" them directly on your nails like the vid shows is a bit far-fetched. ;)

To be perfectly honest I'd expect someone like the Japanese or South Koreans to invent animated nails like that regardless of the "diamond battery" idea within the next 5 or 10 years. It just seems like the kind of "fashion trend" that they'd be likely to come up with.

There is a fun science bit here: the higher the half-life the higher the current, but the shorter it'll last. So that's a fun trade-off

Strike that, reverse it. The shorter the half-life the higher the current, but the shorter it'll last.

my b, yeah, short half-life, high particle output was my thinking.
