Researchers in Tokyo, Japan, these super-flexible electronic displays are the thinnest ever, at an incredible 3 micrometres thick. How thin is that, exactly? Oh about 0.003 mm – more than 13 times thinner than a human hair.

 Not only are these the thinnest ever electronic displays embedded with minuscule LED lights that you can adhere to your skin, they’ve also overcome a bunch of really important challenges that made the rest of them less-than-viable for the actual market.

Arrangements of PLEDs can also display more complex information. Below, you can see seven red bars that form letters and numbers, like a calculator screen on your hand.

Making any piece of ultra-stretchy electronics is often a matter of sandwiching materials together to produce something with the right properties, whether that’s a red light or a method of sensing pressure. In this case, the researchers added a new protective coating, called a passivation layer, to various kinds of e-skin.

The experiment tested an e-skin that combined red and green PLEDs with a flexible sensor that measures oxygen levels through (real, human) skin. When laminated to a finger, the sensor kept delivering measurements for four days in ordinary air.

The result is able to crumple and bend without damage.

The lights used in the displays are called organic polymer light-emitting diodes (PLEDs), which are small sheets of energy-efficient lights that turn off and on when exposed to an electrical pulse.

The study’s findings don’t apply to the whole, broad category of electronic skin. In fact, it’s already possible to make super-thin tattoo-like monitoring devices that last for weeks, if you use the non-organic conductive material.
