  • Patent number: 8283834
    Abstract: A power generating apparatus (100) is provided with first substrates (2b, 2c) whereupon a first electrode (3) is arranged on one surface; a second substrate (1a) which includes a second electrode (6) arranged to face a first electrode on the one surface side of the first substrate; and sliding mechanisms (10, 11, 12, 13 and 14) arranged at least on the one surface side or the other surface side of the first substrate. The sliding mechanism holds the first substrate so that the first substrate moves relatively to the second substrate in a second direction (X direction) while suppressing movement of the first substrate in a first direction (Z direction).
    Type: Grant

  • Patent number: 8212450
    Abstract: An electrostatic operating apparatus (electrostatic induction generator) includes a first substrate having a first electrode and a second electrode and set in a state where the first electrode and the second electrode are electrically separated from each other at least on the substrate and a second substrate including an electret member, wherein the first substrate and the second substrate are so provided as to be opposed to each other at an interval and so formed as to be movable relatively with each other, and at least one of the first electrode and the second electrode is so formed as to be capacitively coupled with the electret member.

  • Patent number: 7525205
    Abstract: An electric power generator capable of using external vibrations in various directions to generate power. A fixed substrate having a surface with a plurality of electret electrodes and a movable substrate having a surface with a movable electrode are spaced from each other. The fixed substrate is fixed in the electric power generator. Spring driving bodies support the movable substrate so that the movable substrate elastically moves in any direction within an XY plane when receiving external vibrations.
