Samsung is betting on elastic screens for the connected accessories of the future, such as activity bracelets. The Korean R&D lab has managed to create a kind of screen that can stick to the skin to pick up the heart rate and display it in real time.
Technologies aroundhave taken a good ten years to be mastered and adopted by the High-Tech sector in the form of foldable mobile screens. Here now come the beginnings of the elastic screen. Screens that could be distorted and stretched in all directions like rubber bands. And it is precisely Samsung, one of the precursors of flexible screens which has just unveiled its research in the via a publication in .
Researchers from(Sait), Samsung’s Research & Development center dedicated to future cutting-edge technologies, have developed a screen that can be stretched by 30% while maintaining stable performance. This type of screen incorporating pixels was used to display real-time data collected by a photoplethysmography (PPG), in other words, the heart rate sensors found under many smartwatches. So it’s kind of a bandage elastic that is applied directly to the skin which allows measurements to be taken and displayed.
As forin their time, deforming an electronic device without breaking the components or damaging the electrical connections remains complicated. The researchers first designed a compound elastic serving as for electronic components. The concern is that this is precisely vulnerable to temperature rises generated by . To address this concern, the researchers adapted its molecular composition to strengthen its .

In addition, it was necessary to adapt theto certain areas. This is the case of the one integrating the pixels of the Oled, where the elasticity must be less important than elsewhere. The researchers also used stretchable conductive materials so as not to break the , or distort the pixels themselves. Once placed on the wrist of the wearer, the elastic display surface has been able to remain stable and retain its properties despite the . In the end, the sensor and the Oled screen continued to function even after being stretched 1,000 times. The other advantage is that stuck to the skin, this system managed to capture the heartbeat signal 2.4 times more important than a standard sensor.
According to scientists, such a system could in the long term replace watches andthat one to measure our biometric data during the or activities. Researchers are already imagining many health-oriented for this electronic skin.
What you must remember
- Samsung has created a screen that can be stretched like a rubber band
- It was used as a heart rate sensor and on-skin display
- This type of screen could eventually replace an activity bracelet for example
