According to foreign media reports, Japan's Toyohashi University of Technology and Okinawa Institute of Science and Technology Graduate University have jointly developed a flexible, multi-point Micro LED array film that can be flexibly adhered to It is attached to the brain and illuminates a specific area of the brain. It is expected to be free from the constraints of time and space, and to freely control complex brain activities. It has broad application prospects in the field of optogenetics.

The overall size of the flexible Micro LED film is less than 100 μm and the thickness is several μm. Even in the case of bending, the Micro LED can maintain the same performance. In addition, the researchers demonstrated that when the flexible Micro LED film is covered on the surface of the mouse brain, bright blue light can be obtained and used in practical optogenetic experiments.
According to reports, in recent years, with the development of optogenetic technology, light can realize the control of neural activity, but this technology requires the use of light sources that are thin, flexible and harmless to living tissue. The new Micro LED film developed by the Japanese research team is highly suitable for this kind of research. The researchers expect that this flexible Micro LED technology will create a new field of neuroscience research, with the aim of comprehensively understanding the underlying neural activity, behavior and disorders. brain information.
The findings were published in the journal Applied Physics Press on March 18.
