Samsung develops OLED skin display that doubles up as a fitness tracker


How cool would it not be to put on simply a skinny OLED patch in your wrist as an alternative of cumbersome smartwatches for fitness monitoring? Straight out of a sci-fi film, Samsung has announced its subsequent large breakthrough in versatile display know-how — “stretchable electronic skin.”

Researchers on the Samsung Advanced Institute of Technology (SAIT) have developed a stretchable OLED display that can connect to the wrist to supply fitness monitoring info to customers. It’s built-in a PPG coronary heart price sensor, creating what Samsung calls the “stretchable electronic skin form factor.”

SAIT researchers examined the machine by attaching it to the interior wrist close to the radial artery. Doing this allowed them to verify that the motion of the wrist didn’t deteriorate the display.

During the check, the stretchable OLED remained dependable with skin elongation of up to 30%. The check additionally confirmed that the sensor and OLED contraption can proceed to work stably even after 1,000 stretches.

How did Samsung make the OLED skin display?

The SAIT staff modified the composition and construction of elastomer, a polymer compound with excessive elasticity and resilience, and used present semiconductor manufacturing processes to use it to the substrates of stretchable OLED shows and optical blood-flow sensors. Samsung claims that is a first for the trade.

Will Samsung commercialize this OLED skin display?

According to Samsung, the patch seems like a a part of the skin. It can be utilized to measure biometric information whereas sleeping or exercising. You can even verify your fitness information proper on the OLED display screen with out the necessity to connect with an exterior machine.

“The technology can also be expanded to use in wearable healthcare products for adults, children, and infants, as well as patients with certain diseases,” defined principal researcher Youngjun Yun.

The stretchable sensor additionally makes steady coronary heart price measurement doable with a excessive diploma of sensitivity in comparison with present mounted wearable sensors.

However, Samsung’s analysis continues to be within the early levels. The researchers say that they purpose to commercialize the tech by rising system decision, stretchability, and measurement accuracy to a stage that makes mass manufacturing doable.
