How Electronic Tattoo's Work

This thin film of elastic gadgetry is essentially a temporary tattoo — you know, kind of like those lick-and-peel numbers you used to find in bubblegum wrappers as a kid. Those temporary tattoos were glue-and-ink transfers. Epidermal electronic systems, on the other hand, adhere to skin in a different way. They conform to the skin’s texture, sticking firmly in place for a matter of days. But an electronic tattoo looks less like a fire-breathing dragon and more like a thin circuitry-filled sticker. Also, it doesn’t help convince your classmates that you joined a Chinese street gang over the summer. No, instead it reads your vital signs — eavesdrops on the language of your internal systems and whispers that data to the physicians who prolong your life.
