How awesome would it be to track your fitness with simply a thin OLED patch on your wrist rather than big smartwatches? Samsung has revealed its next great accomplishment in flexible OLED display technology: “stretchable electronic skin,” or in other words “Samsung OLED skin patch” which sounds like something out of a science fiction film.
Samsung Advanced Institute of Technology (SAIT) researchers have designed a stretchable OLED display that can be worn on the wrist to provide consumers with fitness tracking statistics. Samsung calls it the “stretchable electronic skin form factor” since it includes a PPG heart rate sensor.
Samsung OLED skin patch was put to the test by SAIT researchers who attached it to the inner wrist near the radial artery. They were able to ascertain that the wrist movement had no effect on the display by doing so.
With skin stretching up to 30% during the test, the stretchable OLED remained trustworthy. The test also verified that the sensor and OLED contraption can work reliably even after 1,000 stretching attempts.
How did Samsung make the stretchable OLED display?
The SAIT researchers altered the structure and form of elastomer, a polymer compound with great elasticity and robustness, and applied it to the substrates of stretchable OLED displays and optical blood-flow sensors using conventional semiconductor manufacturing procedures. This flexible OLED display, according to Samsung, is a first in the sector.
Will Samsung OLED skin display be commercialized?
The patch, as per Samsung, seems like a natural part of the skin. This stretchable electronic skin may be used to track biometric information when sleeping or working out. You can also monitor your fitness data without having to connect to an external device on the OLED screen.
Youngjun Yun, the lead researcher, stated, “The technology can also be expanded to use in wearable healthcare products for adults, children, and infants, as well as patients with certain diseases.”
In comparison to contemporary fixed wearable sensors, the stretchable sensor allows for continuous heart rate monitoring with a high degree of sensitivity.
Samsung’s research, on the other hand, is still in its early phases. The researchers hope to commercialize the Samsung OLED skin patch by improving system precision, stretchability, and measurement accuracy to the point where mass production is feasible.
