‘Smart’ Tattoos

Forget smartphones and watches. DuoSkin, a new product from Microsoft and the MIT Media Lab, can turn your epidermis into a touch pad. Or a remote. Made with naturally conductive gold leaf, DuoSkin places a technological interface directly on your body. One potential application would include a Bluetooth-like chip so wearers could sync their temporary tattoo to a music system, then swipe it to change volume. Another version changes colors. The process is designed so people can customize both form and function for a tattoo that lasts only a day. The goal, says lead researcher Cindy Hsin-Liu Kao, is to create technology that’s as personal as lotion or makeup, so “it really blends into the wearer’s identity.”
