<P>PROBLEM TO BE SOLVED: To provide a power generation device that efficiently performs piezoelectric power generation using vibratory displacements of three axial components (in front and rear, right and left, and upward and downward directions). <P>SOLUTION: Piezoelectric modules 30a to 30d suspending a weight body 20 are provided in a container-like casing 10. The piezoelectric element modules 30a to 30d make warpage change according to the three axial components (in the front and rear, right and left, and upward and downward directions) to perform piezoelectric power generation. An operating liquid 70 and piezoelectric modules 50a to 50e are provided in the weight body 20, and the piezoelectric modules 50a to 50e are given warpage change by an operating liquid 70 in accordance with movement of the weight body 20 to perform piezoelectric power generation. Efficient power generation is then performed which uses the vibratory displacements of the three axial components. <P>COPYRIGHT: (C)2010,JPO&INPIT |
