We’ve seen stick-on circuits capable of putting a phone on your finger, and while they’re certainly incredible to behold, they aren’t accessible outside of world-class research labs and production lines.
But a technology called DuoSkin, by MIT Media Lab and Microsoft Research, could enable anyone to create custom, wearable circuits—and apply them as easily as a temporary gold leaf tattoo. And not in 10 or 20 years, but using craft store materials, today. In a new paper being presented at the International Symposium on Wearable Computers next month, the research team details how you can shape circuits using any graphic design software, cut the pattern out of a sandwich of tattoo paper and vinyl, and then coat that vinyl with gold leaf. Not only is gold leaf en vogue, as far as temporary tattoos go; gold leaf also makes the tattoo conductive to electricity, and your touch.
