Researchers at Georgia Tech have invented a painless tattoo. Instead of a needle, it is a patch that has thousands of microscopic needles so small that you can’t even feel them. The needles make the tattoo ink and you just stick it on, let the ink soak in, and then the results are permanent.
There is a lower risk of infection this way because the tattoo will not cause bleeding. The needle isn’t even metal, it is a tattoo ink encased in a material strong enough to penetrate your skin and then it dissolves.
