    摘要: A speaker unit has a plurality of sound sources each outputting a sound wave. The compressional, sound wave output from the speaker unit arrives, or vibrates air, which moves a movable part of a three-axis acceleration sensor, or a microstructure of a chip to be tested TP. As the movable part thus moves, a value in resistance accordingly varies, and such variation is measured as based on an output voltage provided via a probe. A control unit determines a property of the three-axis acceleration sensor from a value in property as measured or measurement data. Furthermore, the plurality of sound sources can be spaced by a pitch of a predetermined value set as based on their difference in the distance to the movable part of the three-axis acceleration sensor and the wavelength of the test wave to apply a composite test wave to the movable part such that the composite sound wave's composite sound field is maximized.

    摘要: A displacement measurement apparatus for a microstructure according to the present invention measures a displacement of the microstructure having a fixed portion electrode including a first electrode and a second electrode and a movable portion electrode located oppositely to the fixed portion electrode. A bias generating circuit applies a bias signal to between the first electrode and the movable portion electrode so that influence of a noise signal on a detection signal picked up from between the second electrode and the movable portion electrode may be reduced. A C/V converting circuit converts a capacitance change that is picked up from between the second electrode and the movable portion electrode into a voltage. A detecting circuit detects a displacement of the movable portion electrode based on the voltage.
