From TFA: > Applied with a handheld tool, the patch stays on the skin for around 10 to 15 minutes You'd notice.
Even when drunk? I’m not saying it’s a real danger (people willing to do that could already do a lot of other stuff) but I wouldn’t be so sure that you couldn’t do it either.
Neat concept, but the density of needles seems quite low for tattoing, and that is likely why the linework of the tattoos in those pictures is so blurry. While getting tattooed, the needle will puncture skin and deposit ink typically 1500+ times per minute. The most specific that this article gets is saying the patches have "hundreds" of needles. At the high end (999 needles in a patch) this means that this patch has…
Makes you wonder why; if we can cut steel in half with water, would it be possible to deliver ink to a specified depth with high pressure “ink needles” (microscopic high pressure short burst of liquid ink)? Like a super high pressure inkjet printer. Though, I assume a more practical point might be a robot that would have an ink-feeding extremely fast cycling device for doing tattoos that can complete them in a fracti…
Maybe this belief comes from being a sysad - dot matrix printers never did me no harm, but inkjets are demonic.
This is neat for small flash pieces. I’m not sure I want to imagine the process for getting a half sleeve of one’s own design applied this way, fifteen millimeter diameter at a time.
Presumably larger prints will arrive, but you still have the trouble of mapping to a non-euclidean surface. Unless of course you're tattooing Euclid.

My guess is that pressure-blasting the ink will not be more comfortable than driving it in with a physical needle. Maybe this belief comes from being a sysad - dot matrix printers never did me no harm, but inkjets are demonic.

Was this meant seriously? I literally used those graphics 40 years ago (it's from a wonderful program called PrintShop ( https://news.ycombinator.com/item?id=41087798 )
The needle grid reminded me of dot-matrix printers which then brought me back to hours spent with PrintShop. The similar resolution and size of this device and PrintShop graphics tickled me with retro-future visions of people sitting at an Apple II picking out tattoo designs to be printed on themselves.

You can't cut steel in half with water. Waterjet cutting requires an abrasive media like garnet to cut through hard materials. Water is simply the power source that accelerates the garnet to Mach Jesus.

Approximate tattoo pain by location on body: https://www.healthline.com/health/body-modification/pain-tat...
The choice of `medium-light blue`, `yellow`, `medium-dark blue` (!?), `red` for the pain guage is definitely something. I almost missed that there were 4 colors until the second chart
