Flexible Micro LEDs Can Control Behavior of Neurons

A KAIST research team has developed flexible vertical micro LEDs (f-VLEDs) using anisotropic conductive film (ACF)-based transfer and interconnection technology. The team, led by Professor Keon Jae Lee from the Department of Materials Science and Engineering and Professor Daesoo Kim from the Department of Biological Sciences, also succeeded in controlling animal behavior via optogenetic stimulation of the f-VLEDs.
