Patents by Inventor Kee Ryu

Kee Ryu 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).

  • Soft MEMS
    Patent number: 8431080
    Abstract: A microscale polymer-based apparatus comprises a substrate formed from a first polymer material and at least one active region integrated with the substrate. The at least one active region is patterned from a second polymer material that is modified to perform at least one function within the at least one active region.
    Type: Grant
    Filed: June 1, 2007
    Date of Patent: April 30, 2013
    Assignee: The Board of Trustees of the University of Illinois
    Inventors: Chang Liu, Jonathan Engel, Kee Ryu
  • Multiple stage MEMS release for isolation of similar materials
    Patent number: 7838321
    Abstract: This describes a starting structure and method for forming a micro-mechanical device. These devices have several uses in both government and commercial applications. The starting structure can be sold or supplied to others who will then make a final product, or it can be used directly to make a final product. An appropriate use of this starting structure is to make deformable devices useful in an inkjet printing device.
    Type: Grant

    Date of Patent: November 23, 2010
    Assignee: Xerox Corporation
    Inventors: Peter J. Nystrom, Nancy Jia, Kee Ryu
  • Microfabricated micro fluid channels
    Patent number: 7737045
    Abstract: A fluid delivery system including a first substrate having a micro-channel and a well both formed through the first substrate. The fluid delivery system also includes a second substrate and a delivery channel. The second substrate is on the first substrate and the delivery channel is formed between the first and second substrates. The delivery channel provides fluid communication between the micro-channel and the well.

  • Microfluidic systems and components
    Patent number: 7351303
    Abstract: Microfluidic systems and components. A microfluidic system includes one or more functional units or microfluidic chips, configured to perform constituent steps in a process and interconnected to form the system. A multi-layer microfluidic system includes a separate dedicated fluid layer and dedicated electromechanical layer connected via through-holes. Electromechanical components are formed on the electromechanical layer.
