Steven Overly of The Washington Post has the story:
Scientists at the MIT Media Lab and Microsoft Research have designed metallic body art that can control and communicate with electronic devices, such as smartphones or laptops.
DuoSkin temporary tattoos, which can be made at home and wash off in a day, use the electrodes present in inexpensive gold leaf to create a conductive surface. The gold leaf and a thin layer of silicone adhere to the body to create an “interface” on the skin that when touched can indicate certain commands to your electronic devices.
