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.
Ifølge rapporter, i de senere år, med udviklingen af optogenetisk teknologi, kan lys realisere kontrollen af neural aktivitet, men denne teknologi kræver brug af lyskilder, der er tynde, fleksible og harmløse for levende væv. Den nye Micro LED-film udviklet af det japanske forskerhold er særdeles velegnet til denne form for forskning. Forskerne forventer, at denne fleksible Micro LED-teknologi vil skabe et nyt felt inden for neurovidenskabelig forskning med det formål at forstå den underliggende neurale aktivitet, adfærd og lidelser. hjerneinformation.
Resultaterne blev offentliggjort i tidsskriftet Applied Physics Press den 18. marts.
