Title: Mei-Chih Hung: Inventions in Nanoparticle Processing and Optical Attenuation

Introduction

Mei-Chih Hung is an inventor based in Changhua, Taiwan, whose work includes materials processing and optical technologies. Her patent record includes 2 patents, and she is associated with the Industrial Technology Research Institute.

Latest Patents

Hung’s patent, “Method for Transferring Inorganic Oxide Nanoparticles from Aqueous Phase to Organic Phase,” describes modifying nanoparticle surface polarity and using suitable solvents to move the particles from an aqueous medium into an organic one. The resulting dispersion can be combined with a polymer to create a composite in which the nanoparticles are uniformly distributed.

Her patent, “Variable Optical Attenuator Derived from Sol-Gel Material and Manufacturing Method Thereof,” describes a waveguide-based optical attenuator. The process forms cladding layers and a waveguide with core and attenuation regions, then places an electrode above the attenuation region. The waveguide uses a sol-gel material made by mixing metal alkoxide and organically modified silicon alkoxide solutions and heating the mixture.
