VIBRATION POWER GENERATOR, VIBRATION POWER GENERATING DEVICE AND COMMUNICATION DEVICE HAVING VIBRATION POWER GENERATING DEVICE MOUNTED THEREON

摘要

Generating efficiency of a vibration power generating device, which generates power by vibration in the biaxial direction, is improved. The vibration power generating device is provided with: a first substrate (101) and a second substrate (106); a first electrode (104) formed on the first substrate; a fixed structural body (103); elastic structural bodies (102X, 102Y) which connect the first substrate and the fixed structural body with each other; and a second electrode (105) formed on the second substrate. Since the overlapping area of the electrodes is increased by arranging rectangular or square conductor parts (104a) of the first electrode and rectangular or square conductor parts (105a) of the second electrode in a checkerboard pattern, a generation region where power is generated by vibration is increased.
