Yong-Lae Park 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).

  • Stretchable two-dimensional pressure sensor
    Patent number: 8316719
    Abstract: A pressure sensor for measuring the location and intensity of an applied pressure, including an elastomeric sheet; and a plurality of micro-channels embedded in the elastomeric sheet.
    Type: Grant
    Filed: November 12, 2010
    Date of Patent: November 27, 2012
    Assignee: President and Fellows of Harvard College
    Inventors: Carmel S. Majidi, Robert J. Wood, Phillippe Bérard, Yong-Lae Park
  • Process for manufacturing shell membrane force and deflection sensor
    Patent number: 8257991
    Abstract: A sensor for force is formed from an elastomeric cylinder having a region with apertures. The apertures have passageways formed between them, and an optical fiber is introduced into these passageways, where the optical fiber has a grating for measurement of tension positioned in the passageways between apertures. Optionally, a temperature measurement sensor is placed in or around the elastomer for temperature correction, and if required, a copper film may be deposited in the elastomer for reduced sensitivity to spot temperature variations in the elastomer near the sensors.
    Type: Grant
