Popis:	A development of a biocompatible, optical stimulation device capable of adhering to the brain surface and activating spatially separated brain regions is necessary for in vivo optogenetic applications. In this study, a hollow structure for isolating the microLED epitaxial layer was fabricated using the anisotropic KOH wet-etching method. Using a thermal release sheet, a method to transfer microLEDs onto a biocompatible parylene film was established without rotation or misalignment of the microLEDs while retaining their characteristics. Accordingly, a flexible microLED array film was fabricated, which adhered to the surface of the brain of a mouse and exhibited blue emission.
