[Breaking] Samsung developed stretchable OLED, sticks to skin and monitors health
In addition to the smartphone market, Samsung is also known as a leader of various display innovations, and the foldable displays implemented in the Galaxy Fold/Flip and Galaxy Z Fold 2 are the perfect examples to understand its research and development on display technologies.
After successfully developing flexible displays, many peoples thinking about what the next big development in display technology will be. In a recent development, researchers at Samsung’s in-house R&D unit Samsung Advanced Institute of Technology have successfully melded a stretchable OLED display.
Staff researcher Yeongjun Lee, co-first author of the paper said, “We applied an ‘island’ structure to alleviate the stress4 caused by elongation.”
This organic light-emitting diode display merged with a photoplethysmography sensor into a single device to measure and display the user’s heart rate in real-time. In order to make the sensor and display stretchable, the researchers used a specially modified “elastomer”.
“The technology can also be expanded to use in wearable healthcare products for adults, children and infants, as well as patients with certain diseases,” said principal researcher Youngjun Yun, corresponding author of the paper.
By using the elastomer, the sensor, and display maintained to operate normally even without showing any performance degradation with elongation of up to 30 percent, in their test. Moreover, this stretchable OLED also continued to work stably even after being stretched 1,000 times.
Principal researcher Jong Won Chung, co-first author of the paper said, “Our research is still in the early stages, but our goal is to realize and commercialize stretchable devices by increasing system resolution, stretchability, and measurement accuracy to a level that makes mass production possible.”
Aside from the heartbeat sensor that was applied in this test case, Samsung plans to combine stretchable sensors and high-resolution freeform displays to enable users to monitor things like peripheral oxygen saturation, electromyogram readings, and blood pressure.

Samsung’s latest foldable phones come with Google Messages by default. The company has now revealed the reason behind this move on Galaxy devices. Samsung says Google Messages replaced Messages to foster RCS adoption.
According to AndroidAuthority, a source explained Samsung’s decision to switch to Google Messages as the default messaging app. The recently released Galaxy Z Flip 6 and Z Fold 6 come with Google Messages with RCS enabled by default.
Looks like promoting Google Messages on Galaxy devices will boost RCS adoption. Samsung Messages isn’t already installed on newer phones. However, one’s stopping you from getting it on your Galaxy from the Galaxy Store.
While many apps support the RCS feature, Google Messages offer the best user experience. Making it a default messaging app is an effort to boost the adoption of RCS tech. Apple is also preparing to bring RCS chat functionality to iMessage for iPhones.
What Samsung source said:
- Even if messaging apps follow the RCS standard, the availability may be limited depending on which app the other party uses. That’s why we decided to make Google Messages the common messaging platform, allowing Galaxy users to communicate more freely. This also enables a messaging app to respond to changes of the RCS standard more quickly and efficiently.
Previously, Samsung devices launched in the US came with two messaging apps. This time, the company has removed the Samsung Messages. During the first setup, users are notified that Google Messages is the default messaging application.
Samsung SmartThings gained the international standard ISO/IEC 27001:2022 certification. The company has officially announced this major development in its global connected living platform.
SmartThings received ISO/IEC 27001:2022 certification for information security management systems. Certification reiterates that the SmartThings Cloud operates per international standards.
To be certified, a company has to meet the standard across a total of 123 detailed items, including policies for information security, access control for information assets, and incident response.
SmartThings receiving the ISO 27001 certification is the result of our sustained focus on the protection of information in a hyper-connected world with exponentially increasing intelligence.
Seungbum Choi, Executive Vice President and Head of Device Platform Center at Samsung Electronics said “this is just another step in our drive to fortify the platform’s security. We will continue to find new ways to ensure that SmartThings’ personalized services are provided even more safely.”
BSI Prez says that they have recognized that the operation capability and security level of Samsung SmartThings is excellent. It will further boost trust in the SmartThings platform and strengthen business competitiveness.
ISO 27001 is the leading global standard for ISMSs and was established by the International Organization for Standardization. It provides companies with guidance to manage the risks to information assets systematically and achieve information protection goals.
Samsung Health app integrated the Dr.diary (Doctor Diary) glycated hemoglobin feature. The blood sugar management platform announced the launch of its glycated hemoglobin estimation functionality on Samsung’s Health application.
According to ETNews, Dr.diary announced the integration of a glycated hemoglobin level feature in Samsung Health. Galaxy users will now be able to check the estimated glycated hemoglobin level provided by Doctor Diary.
To activate the feature, Health app users will have to permit certain conditions of data in the Blood Sugar service. It is worth noting that glycated hemoglobin is a key figure for diabetes diagnosis, which users will find worth using in the Health app.
Established in 2017, Dr.diary is a blood sugar management platform. It analyzes and predicts the changes in glycated hemoglobin using its own algorithm. Earlier this year, the firm secured a patent for “glycated hemoglobin estimation based on blood sugar data table.”
Song Je-yoon, CEO of Doctor Diary, said, “With our predicted glycated hemoglobin level prediction algorithm being installed in Samsung Health, more people will be able to recognize their glycated hemoglobin level and manage their health more efficiently.”
Glycated hemoglobin (HbA1c) is a standardized numerical value of the percentage of hemoglobin, such as hemoglobin, which has been glycated by glucose. Glycated hemoglobin reflects the average blood sugar level over the past 2-3 months.
Samsung Health (with Wear OS Galaxy Watch) users can conveniently check their estimated glycated hemoglobin level within the app and use this information to manage their blood sugar levels through diet and exercise.
