MIT researchers develop temporary tattoos that can control smartphones

This movie shows gold leaf temporary tattoos that can be used to control devices through touch created by a group of PhD students and researchers at MIT’s Media Lab.

The team, led by PhD student Cindy Hsin-Liu Kao, designed the DuoSkin transfers to look like gold and silver flash tattoos, popular at music festivals.

But unlike regular stick-ons, DuoSkin is made from gold metal leaf. As a conductive material, it can be hooked up to an electronic circuit that responds to touch.

In the current prototype, the gold leaf traces are connected to a microcontroller and wireless communication unit that enables interaction with other devices.
