Abstract
A power generating device includes a first substrate having a first electrode and a first positioning electrode being chargeable with a first polarity on a first surface, and a second substrate movable within a predetermined range from a static position in the planar direction of the first substrate and having a second electrode and a second positioning electrode being chargeable with a second polarity opposite to the first polarity on a second surface opposing the first surface. Overlapping the first positioning electrode and the second positioning electrode at least partially in plan view of the first substrate in the static position can cause the second substrate to return to the static position due to electrostatic attraction generated between the first positioning electrode and the second positioning electrode.
