the electronic skin fitted with \'disco lights\': sticky film could lead to wearable screens that track your health and even show films

Forget to watch movies on your mobile phone-you can watch movies directly on your back of hand soon.
Scientists have designed a new kind of super
Thin electronic skin with multiple functions
Color digital display. The \'e-
The skin contains red, green and blue LEDs that are integrated into flexible materials and can be applied like removable tattoos.
Scroll down to watch the video it improves the prospect of creating a screen that can be connected directly to the human body, just like the second skin.
For example, the technology can also be used to produce a new generation of sensors to monitor the oxygen levels of athletes.
Takor Takao Someya, an engineer at the University of Tokyo who led the work, said: \"The emergence of mobile phones has changed the way we communicate.
Although these communication tools are getting smaller and smaller, they are still independent devices that we must carry with us.
\"If we had a display that could be attached to the body, or even show our emotions, stress, or anxiety, what would the world look like?
\"In addition to not having to carry devices all the time, they can enhance the way we interact with people around us, or add a whole new dimension to how we communicate.

The researchers designed a protective film with a thickness of less than two microns.
50 times thinner than human hair.
They embedded a transparent oxidized indium tin electrode in this film.
Using this, they are able to produce highly flexible polymer light-
LEDs (LEDs)
And organic photo detectors, they are thin enough to bend and twist as the body moves.
The protective film is formed by alternating layers of inorganic silicon oxyacetate materials with organic p-px materials, which prevents the passage of oxygen and water vapor.
Tests show that these devices can last for several days when they are connected to the skin.
Researchers reported their findings in the journal Scientific Progress, testing the technology by creating a wearable sensor to measure blood oxygen levels.
Combining red and green polymer LEDs with photodetectors, they are able to make a device that can be connected to the back of the patient\'s hand.
By measuring changes in the color of light passing through the skin, the device can determine blood oxygen levels and display them on the screen on the back of the hand.
Similar devices can be used to measure the pulse rate, they say, but in the end they want to produce detailed LED screens that can replace the phone.
Professor Someya and his team added: \"It is so extreme in terms of flexibility, weight and stretching that e-
Skin with a variety of electronic functions, such as sensors and displays, can be worn on the surface of human skin.
Ultimately, flexible organic optical sensors can be laminated directly on organs to monitor blood oxygen levels during and after surgery.
