You may soon be able to control your music's volume or change the TV channel simply by swiping on your forearm after the invention of a temporary tattoo that can be used to control a mobile phone.
Researchers at the Massachusetts Institute of Technology and Microsoft have demonstrated technology that affixes gold leaf patterns to a person's skin, creating a computer circuit.
The inexpensive material would be able to respond to touch, allowing its wearers to swipe as if on a computer's trackpad or smartphone touchscreen, to control the phone.

While it is not the first time that ways to create on-skin interfaces have been developed, the researchers said their "DuoSkin" system was cheaper, more comfortable and more attractive than other inventions such as copper tape.
