Abstract: PURPOSE: An apparatus and a method for measuring the three-dimension rotation angle using are provided to conveniently measure the three-dimension rotation angle of an object by using only an acceleration sensor. CONSTITUTION: An apparatus for measuring the three-dimension rotation angle (1) includes a first acceleration sensor (100), a second acceleration sensor (200), and a rotation angle calculation unit (300). The first acceleration sensor is attached to an object and calculates a first acceleration value by measuring the acceleration of three axes based on a first coordinate axis. The second acceleration sensor is attached to the object and calculates a second acceleration value by measuring the acceleration of three axes based on a second coordinate axis different from the first coordinate axis. The rotation angle calculation unit calculates the rotation angle by using the first and second acceleration values.

Abstract: PURPOSE: An eddy frequency measuring device is provided to prevent a fracture due to external shock or a case of repeated curving by an eddy. CONSTITUTION: An eddy frequency measuring device comprises the following details: A body(310) is adhered outside of a structure within the occurrence of an eddy. An eddy frequency measuring part(200) comprises an piezoelectric film(210) and an electrode(220), and measures the eddy frequency. The piezoelectric film is fixed in a side of the body, generates a deformation due to a vibration caused by an eddy occurred in the structure, and generates an electronic signal. The electrode is placed on an extended line of the piezoelectric film, fixed in another side of the body, and generates the electric signal caused by the deformation of the piezoelectric film. An eddy frequency confirming part confirms coincidence of the natural frequency of the structure and the eddy frequency measured by the eddy frequency measuring part.
