The Advent of Electronic Tattoos

I’ve always found tattoos vaguely disagreeable, but this story piqued my interest. Scientists are working on inserting electronic number displays beneath the skin (think of the numbers on a digital clock) called “smart skins.” In the short term this could be used for something as simple as a watch embedded in the back of your hand, or much more helpfully, a display showing vital signs for people in hospitals. That’s a game changer for anyone with diabetes or a heart condition. In the long term, imagine this technology as it gets better and more complex. You could have a giant chest tattoo you change once a week, or an effective way to swap out your ex-girlfriend’s name when your relationship implodes. Tramp stamps will become downloadable murals of science fiction.
