A tattoo is a form of body modification, made by inserting ink, either indelible or temporary, into the dermis layer of skin to change pigment. Generally Tattoos are the part of Fashion but now it will control the electronic devices.
MIT researchers and Microsoft Research have created unique type of temporary tattoo, that will be not only attractive but also work as controller for electronic devices. That means computer, Smartphone etc, can be controlled by just tapping on the skin. These tattoos are called DuoSkin, and applied like any other temporary tattoo. It is made up of gold leaf and LEDs and it looks like a piece of Junk Jewellery.
The main objective of the tattoo is to act as input device- Controlling other devices, output device- the tattoo can be used as display screen, and a communication device, via NFC, can be used to transfer the data to other devices or the tattoos.
