A temporary tattoo that can control your smartphone

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.

The researchers developed three different types of tattoos. The first acts as a touchpad to control a computer cursor or adjust a music player. The second uses thermochromic pigments that change color when body temperature rises. Finally, the third uses near field communication technology to transmit personal data, such as photos, between your phone and the tattoo.

The scientists wanted to show that wearable technology can be really customizable.

“It’s something that you own and not a one-size-fits-all wearable. You can design it and it can really cater to your needs and your personal sense of style,” said Cindy Hsin-Liu Kao, one of the researchers behind the project.

More than just a fashion accessory, the DuoSkin tattoosfurther blur the line between the human body and technology.
