They call this tattoo c. According to the researchers, you can design a circuit using any graphic software, stamp the tattoo in gold leaf, a conductive material, and then apply other commodity materials and components that will make the tattoo interactive.
DuoSkin can be used to turn your skin into a trackpad. You can design it to change color based on temperature, or get data from the tattoo. The tattoo even includes LED lights which creates a sort of glowing display on the skin. This creation may open the doors to change the way we use our gadgets.
