Hyoung Jung Yoo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Drug delivery system including laminated structure
    Patent number: 9351924
    Abstract: One aspect of the present invention relates to a drug delivery system comprising a layered structure where a drug layer and a biodegradable polymer layer for controlling the release of drugs are alternately laminated. The drug delivery system can easily control an in-vivo drug release rate and a release amount.
    Type: Grant

  • Retinal prosthesis system using nanowire light detector, and manufacturing method thereof
    Patent number: 9345568
    Abstract: A retinal prosthesis system can comprise: a flexible substrate; a nanowire light detector which is placed on the substrate, and comprises one or more nanowires of which the resistance changes according to the applied light; one or more micro-electrodes which are placed on the substrate, are electrically connected to the nanowire light detector, and come in contact with retinal cells; and an electric power supply source for applying electric power to the nanowire light detector and the micro-electrodes. The retinal prosthesis system can be implemented into a very thin and flexible substrate type high resolution retinal system by manufacturing a nanowire light detector on a substrate in which micro-electrodes are implemented.
