Tiny new LED

Researchers at the University of Illinois developed a new tiny LED, small enough to fit through the eye of a needle. It will also help them to improve on deep brain stimulation, a therapy to treat movement disorders.    Image © John Rogers, University of Illinois/Beckman Institute

The new tiny LEDs will help neuroscience generally and optogenetics, providing the ability to insert light sources, sensors, and other components into precise locations of the brain yields versatile.



John Rogers of the University of Illinois at Urbana-Champaign, a co-leader of the team that developed them, said to Wired:

”Their dimensions are much smaller than those of an optical fiber, and they are much more mechanically compliant. Those features help minimize tissue damage. Also, they are powered and controlled wirelessly, in a way that allows free motion of the animals, social interactions and other natural behaviors.”

“The ability of these ultrathin, mechanically compliant, biocompatible devices to afford minimally invasive operation in the soft tissues of the mammalian brain foreshadow applications in other organ systems, with potential for broad utility in biomedical science and engineering.”
