We propose wound healing patches using hydrogel as a substrate as an application of new structure Flexible Hybrid Electronics (FHE) based on Fan-Out Wafer-Level Packaging (FOWLP) in which the chiplets are embedded in an organic substrate. In this study, we report on the fabrication of FHE patches for moist photobiomodulation of chronic wounds such as bedsores using NIR-µLED chips with a light source in the near-infrared region and the photobiomodulation effect.
