Researchers at the Samsung Advanced Institute of Technology, or SAIT, have developed a new type of flexible OLED display advanced. Unlike the bendable screens now known, such as those used in foldable Smartphones, these new screens are also “expandable”. As a result, they can be used, for example, on the skin.
Synthetic rubber in OLED technology
Thanks to the application of new and flexible technology and materials, these OLEDs can be extended by up to 30 percent without losing quality and performance. SAIT scientists have successfully adapted the structure of elastomer, a highly flexible polymer compound, so that it can be used in the development of OLED displays.
A prototype developed by SAIT’s Bright Minds is placed on a person’s wrist. The so-called stretchable OLED display is organically combined with the built-in heart rate sensor. The test subject’s heart rate can then be displayed on the screen.
Smart plaster with screen
Scientists expect flexible and stretchable OLED technology to be viable for healthcare use. The screen, which is equipped with built-in sensors for measuring heart rate or other vital functions, for example, can be placed in the form of a sticker. Smart patches, or smart patches, have been in the healthcare field for a long time. They measure vital functions, but do not (yet) have a display.
“The strength of this technology is that you can measure your biometric data for a longer period of time without having to remove the solution when you sleep or exercise, because the patch feels like it’s part of your skin. You can also,” said Young Joon Yoon, principal investigator at SAIT. Display your vital data directly on the screen without having to transfer it to an external device.
