Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have developed a wearable green organic light-emitting diode (OLED) with a 470-nanometer (nm) wavelength that can cure jaundice in infants.
The OLED provides sufficient power for jaundice treatment even at low voltage, durability for over 100 hours of operation, a low operating temperature of less than 35 Celsius degrees, and flexibility that can endure over 1,000 bends at a 2 mm radius of curvature.
The bilirubin level of the infants’ serum reaches 12 milligrams per decilitre (mg/dL) within three hours of being exposed to the OLED, indicating the completed treatment of jaundice.
Unlike existing light-emitting diode (LED)-based jaundice treatment devices currently used at hospitals, the OLED showed uniform and effective treatment functions.
