Samsung – It’s also reported that the stretchable OLED remained up to 30% reliable during testing.
Samsung has just developed a futuristic flexible displlay technology that can be used as a wearable device. This device is said to function as a fitness tracker, replacing smartwatches that are mostly large or smart bands.
Researchers at the Samsung Advanced Instiitute of Technology (SAIT) recently developed an OLED display that can be stretched to be placed on the user’s wrist. This device offers a fitness tracking feature.
Reporting from Gizmochina (June 9, 2021), the OLED screen is even informed that it has an optical light-based (PPG) heart rate sensor. Samsung claims the device with a “stretchable electroniic skin form factor.” The SAIT researchers have testted the device by attaching it to the wrist near the radial artery.
In testing, it was found that the wrist movement did not degrade the quality of the screen. In addition, it is also reported that this stretchable OLED remained reliable with an elongation of up to 30% during testing. The sensor and OLED panel are also durable enough to continue working stably even after 1,000 stretches. SAIT researchers managed to “modify and structure elastomers, polymer compounds with high elasticity and resilience and use existing semiconductor manufacturing processes to apply them to stretchable OLED display substrates and optical blood-flow sensors.”
Samsung claims that this is a first for the industry and adds that OLED will feel like a part of the user’s skin. Moreover, it will even measure biometric data while sleeping or exercising.
“This technology can also be extended to use in health care products that can be used for adults, children, and infants, as well as patients with certain diseases,” said lead researcher Yongjun Yun. Unfortunately, this feature set is still in the early stages of development, and Samsung has not announced when it will be launched commercially.
