A team of researchers from the Faculty of Engineering and Applied Sciences of Nanjing University in China recently unveiled an innovative, ultra-thin display that is flexible enough to be attached to the skin or skin, such as these types of temporary tattoos.

Checking the stopwatch for the time you spent running, or looking at your smartphone screen to see who is calling you may become a thing of the past, thanks to the revolutionary "human machine interface" that allows information to be displayed directly on human skin.

The new innovation, dubbed "alternating current" or "acyl", consists of a transparent photoelectric layer made of fine particles that emit light and are fixed between two layers of nanoflexible silver electrodes.

Ceramic nanoparticles embedded in the rubber polymer make the Aseel display more luminous than anything else, allowing it to appear clearly even in a well-lit room.

What makes the screen precisely so important is that it can be glued to the skin securely, emitting very bright light even at low voltages, and generating little wasted heat that does not exceed 45 ° C.

"The so-called skin sensor may allow continuous monitoring of heart rate, blood pressure, blood oxygen levels and even glucose," said project coordinator Professor Disheng Kong. "The screen will provide visual information for these measures, which are very important for training athletes and biomedical fields."

To prove one of the potential uses of this revolutionary screen, the researchers created a bright stopwatch mounted on the back of a human hand, the numbers were clearly visible, and the resulting voltage was very low.

This device or temporary tattoos may prevent the "transplantation" of slides or fine instruments into the skin or under the skin.

Disheng Kong and his team believe that the new "Aseel" screen could soon contain applications found in smart wearable devices, mini-robots and "human machine interfaces."
