Title: Innovations of Ja Young Bae in Photonic Crystal Technology
Introduction
Ja Young Bae is an accomplished inventor based in Ulsan, South Korea. He has made significant contributions to the field of photonic crystal technology, holding 2 patents that showcase his innovative approach to anti-forgery solutions and sensor technology.
Latest Patents
His latest patents include a photonic crystal structure and an anti-forgery color conversion film comprising the same. The anti-forgery color conversion film features a photonic crystal structure that changes color in response to external stimuli, such as breath. This film consists of a first refractive index layer made from a polymer with a specific refractive index, and a second refractive index layer that is alternately laminated with the first layer. This technology allows consumers to easily verify the authenticity of products containing the color conversion film.
Another notable patent is the color-conversion photonic crystal structure and color-conversion photonic crystal sensor using the same. This invention employs a structure where two layers with different refractive indices are laminated alternately. One of the layers includes a polymer derived from a monomer containing a fluorocarbon group, enabling the photonic crystal structure to respond to humidity and organic solvent concentration. This innovation leads to the development of a color-conversion photonic crystal sensor with excellent sensitivity and reproduction characteristics.
