摘要： 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.

摘要： 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. A self compensation and signal linearization method of the sensor having four electrode sets that are disposed to generate a phase difference signal of 90 degrees comprises: controlling the four electrode sets to respectively output a signal with a phase difference of 90 degrees; acquiring two signals from which common signal components including a drift and an offset are eliminated by subtracting the signals that have opposite phases from among the signals that are output by the four electrode sets; controlling peak values of the two signals from which the common signal components are eliminated to have the same size, and acquiring two signals from which absolute values are taken; and comparing sizes of the two signals from which the absolute values are taken, taking a lesser value, and acquiring a linearized triangular wave.
