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.
Aruannete kohaselt on viimastel aastatel optogeneetilise tehnoloogia arenedes valgus suutnud neuraalset aktiivsust juhtida, kuid see tehnoloogia nõuab õhukeste, paindlike ja eluskoele kahjutute valgusallikate kasutamist. Jaapani uurimisrühma välja töötatud uus Micro LED-kile sobib seda tüüpi uuringuteks väga hästi. Teadlased loodavad, et see paindlik Micro LED-tehnoloogia loob uue neuroteaduse uurimisvaldkonna, mille eesmärk on põhjalikult mõista närvisüsteemi aktiivsust, käitumist ja häireid. aju teave.
