Chinese Researchers Create Stretchable Display Thin Enough to Be Worn as Temporary Tattoo

A team of researchers from the College of Engineering and Applied Sciences at Nanjing University recently unveiled an innovative display that is thin and flexible enough to be worn on skin, like a type of temporary tattoo.

Having to check a stopwatch to see your time while running, or looking at your smartphone screen to see who is calling may soon be things of the past thanks to a new and revolutionary human-machine interface that allows information to be displayed directly on human skin. Called alternating-current electroluminescent (ACEL) display, this new invention consists of an electroluminescent layer made of light-emitting microparticles sandwiched between two flexible silver nanowire electrodes. The ceramic nanoparticles embedded in stretchable polymer make this ACEL display brighter than any other, allowing it be clearly visible even in a well-lit room.
