Ladies and gentlemen, temporary tattoos just got a serious upgrade from when we were kids. Using a process called DuoSkin, scientists in the MIT Media Lab have developed temporary tattoos that have the ability to control your electronic devices. The tattoos in question are modeled after the popular metallic temporary tats that have been all the rage lately.
Scientists have tried to create devices that work along with human skin in the past, but DuoSkin takes it to the next level by being relatively inexpensive to make while also being pretty to look at. The tattoos apply just like a regular temporary tattoo -- by applying water and slowly peeling away the paper cover -- and can be designed into any shape the wearer prefers.
So what do these magical tattoos actually do? They can work as a trackpad for your device, to do things like switch songs on your music player. They can work similar to a mood ring, changing colors depending on your body temperature or emotion. And they can be used to communicate with other devices, such as to scan a movie ticket.
