SkinMarks e-tattoos Can be applied to the skin using water and last a couple of days before wearing off, but while on the skin the unique e-tattoos are capable of providing a number of useful functions and can be used for controlling a wide variety of devices.
Watch the video below to learn more about SkinMarks how they are applied and the functionality of them. Another type of SkinMark is electroluminescent, enabling an image printed on your skin which can light up to signal a phone call or other important notification.
Ultrathin temporary electronic tattoos can now turn body blemishes into touch-sensitive buttons, letting you control your smartphone with your own wrinkles, freckles and other skin features. People intuitively know the location of their own bumps and birthmarks, which makes them ideal locations for touch-sensitive buttons, says Martin Weigel at Saarland University in Saarbrücken, Germany, who has led the research. You could squeeze a freckle to answer a phone call, or slide a finger over your knuckles to change the volume of your music.
Weigel and his colleagues at Saarland University and Google used conductive ink to print wires and electrodes on temporary tattoo paper. The tattoos, which they call SkinMarks, are thinner than the width of a human hair. They are transferred onto the skin using water and last a couple of days before rubbing off. “We make use of the elastic properties of the skin, including bending and stretching,” says team member Jürgen Steimle, also at Saarland University. By having the tattoos responsive to changes in the skin surface, they incorporate multiple commands at one location.
