摘要： The present invention relates to a bimorph type piezoelectric acceleration sensor used in detecting vibrations of a variety of equipment such as a hard disk, CD-ROM and the like and has the objective of providing a bimorph type piezoelectric element for acceleration sensor of a small size, high sensitivity, a narrow range of sensitivity variation and a low cost by forming a freely vibrating part and a supporting means at the same time in single-piece construction through a grinding away process applied to lithium niobate. One section of a structure formed of two of a lithium niobate single-crystal plate directly bonded together with the polarization directions thereof reversed each other is applied with a grinding away process to produce a freely vibrating part (32a) and the remaining section, where no grinding away process has been applied, serves as a supporting member (33a), thus both being formed simultaneously and made integral with each other, and electrodes (31a, 31b) are formed by electroless plating.

摘要： A vibration power generating device includes a first substrate and a second substrate, a first electrode formed on the first substrate, a fixed structural body, elastic structural bodies which connect the first substrate and the fixed structural body with each other, and a second electrode formed on the second substrate. Since the overlapping area of the electrodes is increased by arranging rectangular or square conductor parts of the first electrode and rectangular or square conductor parts of the second electrode in a checkerboard pattern, a generation region where power is generated by vibration is increased.
