Flexible LEDs Get Under the Skin

October 23, 2010 – 9:08 am

John Rogers, a professor from the University of Illinois at Urbana-Champaign has headed up a research effort to develop a flexible and implantable LED array. Collaborating with researchers from the United States, China, Korea and Singapore, Rogers used ultra-thin sheets of inorganic LEDs and photodetectors. Potential applications include medical monitoring, activating photo-sensitive drugs and other biomedical applications.  They also could be used in light-emitting sutures or implantable illuminated plasmonic crystals.

According to the researchers, the lights can bend and twist as much as 75% , which enables them to interfere minimally with movement. The LEDs are encapsulated in a thin layer of silicon rubber to enable them to function well when implanted or when immersed in liquids.
