Samsung researchers have proved the feasibility of commercialized ‘Stretchable’ devices

Although it has developed rollable and foldable displays, Samsung has been chasing different types of displays and extending its display technology. Many people can understand what kind of display technology will be available in the future through Samsung’s technology display. Perhaps in the near future, they will be able to see more forms of display screens.

Recently, researchers from the Samsung Advanced Institute of Technology published a report on a stretchable display, which is the first time in the industry. What Samsung showed was the integration of a stretchable skin patch OLED screen and a photoplethysmography (PPG) sensor into a single device to monitor and display the user’s heart rate in real-time. Samsung said that the device uses a highly elastic polymer compound that can withstand up to 30% of the skin extension, and remains stable after 1,000 stretches. At the same time, it is 2.4 times stronger than would be picked up by a fixed silicon sensor. Because it can be firmly attached to the skin, it has a smaller sound than other sensors and can measure heart rate with high sensitivity.

Related members of the research report said that the advantage of this technology is that it can monitor biometric data for a longer period of time, without the need to remove it during sleep or exercise, just like a part of the skin. Compared with other existing solutions, it feels more natural. At the same time, the biometric data can be checked immediately through the screen without relying on external devices, which is quite convenient. In addition to monitoring heart rate, the stretchable skin patch OLED screen can also display several other health care conditions. In the future, there may be other devices that will also use this display technology.
