According to the Reuters recently, by the three research teams led by German Fraunhofer FEP has developed a flexible OLED bracelet, the bracelet is said to help heal wounds and treat depression, the development of LED chip manufacturers for health Efforts to monitor new areas, etc., echo. “Wearable devices can also be used as fashion items and can provide visibility to outside workers when adjusting to red or yellow frequencies at night,†says Fraunhofer. “The bracelet can help heal when tuned to a certain frequency. Trauma, and this material can help treat depression in a “heads up†dress design.†An OLED (Organic Light Emitting Diode) material emits light from its surface, while an LED chip is a single point source. OLEDs have not yet developed into common general light sources, and manufacturing costs have always been an obstacle. Flexible OLEDs have long promised to offer new lighting opportunities as they can be woven into fabrics of buildings, furniture, clothing and various materials. In addition, not long ago, according to foreign media reports, Korean researchers have also developed an "OLED patch" that can be attached to the skin, using a source of organic light-emitting diodes for damaged areas to help wound healing. . In addition to the development of OLEDs in the health sector, lighting giant Osram is driving infrared LED chips as health monitors in watches and fitness equipment and for facial recognition in security applications.
