MIT and Microsoft teamed up and created a whole new type of wearable tech: a stick-on “tattoo” called DuoSkin, which looks like a metallic design painted on the skin but can control a music player, display info, and store wireless data.

Made of gold leaf and silicone paper that “enable input through capacitive touch sensors, output through thermochromic resistive heating circuits, and wireless communication through NFC chips” (um, sure), DuoSkin wearables will be cheap to make and can be stuck anywhere on the body. (We’d suggest somewhere you can reach without drawing stares.)
