Cindy Hsin-Liu Kao, PhD student at MIT, created this wearable piece of technology; it’s called the Duoskin, and it’s a gold leaf temporary tattoo that can be used as a touchscreen. Her inspiration? Street fashion in Taiwan.

Kao says that metallic jewelry-like temporary tattoos are a growing trend, providing a great opportunity for creating functional fashion. She notes that in Taiwan, there’s a “huge culture” of cosmetics and street fashion, which is affordable and accessible enough that “you can very easily change and edit your appearance whenever you want.” The DuoSkin team wanted to achieve the same thing with their technological twist on the tattoo trend.
