Imagine getting a tattoo that doesn't hurt a bit, that you could put on your body yourself at home, in a fraction of the time it takes to get a piece done these days. Sound good? It will soon be a reality thanks to two researchers at the Georgia Institute of Technology who have developed low-cost, painless, and bloodless tattoos that can be self-administered and have many applications, from medical alerts to tracking neutered animals to cosmetics.
Researchers believe the new self-administered, painless needles will also be able to deliver vaccines as a skin patch containing microscopic needles that could significantly increase the number of people who get vaccinated for the flu. Mark Prausnitz, Regents Professor, School of Chemical and Biomolecular Engineering explains how it works.
