  • Area-varying capacitive sensor, and self compensation and signal linearization method thereof
    Patent number: 9797750
    Abstract: An area varying capacitive sensor for substantially reducing a drift and an offset without performing a complicated process by linearizing a signal while automatically compensating the offset and the drift by additionally disposing an electrode and performing a simple signal process without applying complicated signal processing to an area varying capacitive sensor having a periodic electrode, a self compensation and signal linearization method of the area varying capacitive sensor are provided.
    Type: Grant
    Filed: August 26, 2011
    Date of Patent: October 24, 2017
    Assignee: POSTECH ACADEMY-INDUSTRY FOUNDATION
    Inventors: Won Kyu Moon, Daesil Kang
  • Area-variable type capacitive displacement sensor having mechanical guide
    Patent number: 8242791
    Abstract: An area-variable type capacitive displacement sensor includes: a stationary element; a movable element; an elastic member for providing a force biasing one of the stationary element and the movable member towards a remaining one thereof in a direction perpendicular to a driving direction so that the stationary element and the movable member are maintained in close contact with each other; a power supply; and a signal detecting circuit. The sensor further includes a guide means for correcting an initial alignment error and reducing an operation alignment error between the stationary element and the movable element.
