Optical biomedical measurement device

Abstract

An optical biomedical measurement device is provided. The optical biomedical measurement device includes a substrate, a light source disposed on the substrate, a photodiode sensor disposed on the substrate, laterally spaced from the light source, a plurality of light-blocking walls disposed vertically on the substrate, laterally located on both sides of the light source and on both sides of the photodiode sensor, a sealing layer covering the light source, the photodiode sensor, and the light-blocking walls, a cover plate bonded to the sealing layer, a plurality of light-absorption films vertically aligned with the light-blocking walls, disposed in a plurality of etching regions on a top surface of the cover plate, an optical filter film disposed on the cover plate and the light-absorption films, a plurality of nano-metal particles arranged on the optical filter film with a distance therebetween, and an antibacterial optical film covering the nano-metal particles and the optical filter film.
