E-tattoos turn your skin into smartphone control

Mar 20, 2017, 9:04 AM EDT

Researchers at Saarland University in Saarbrücken, Germany, have developed unique electronic tattoos that can turn skin blemishes into touch-sensitive sites allowing the users to control their smartphones with their wrinkles, freckles or other features. These temporary tattoos, called SkinMarks, respond to elastic changes in the skin surface and can identify multiple commands during their two-day life. 

One can slide a finger over the tattoo on the skin to adjust smartphone volume or bend the finger to bring up play and pause button on skin, notes International Business Times.

Chris Harrison at Carnegie Mellon University is elated with the new research and calls the on-skin devices as next logical step in the wearable technology category, writes New Scientist. Chris backs the argument with the facts that human fingers are quite nimble on their own skin and also human skin offers much more surface area compared to any wearable screen available today.
