Electrostatic induction power generator

摘要

An electrostatic induction power generator includes a spherical member for making a distance between surfaces of a first substrate and a second substrate facing each other constant. A housing is provided with a first reference surface to which a surface of the second substrate facing the first substrate is fixed and which is a positioning reference for the second substrate with respect to the surface facing the first substrate in a vertical direction, and a second reference surface with which the spherical member is slidably in contact and which is a positioning reference for the spherical member with respect to the surface facing the first substrate in the vertical direction. The spherical member is slidably in contact with a surface of the first substrate facing the second substrate.

1. An electrostatic induction power generator comprising:
a first substrate and a second substrate configured to be able to move relative to each other while maintaining a state in which the first substrate and the second substrate face each other; an electret provided on the first substrate; a first electrode and a second electrode provided on a surface of the second substrate facing the electret; and a housing containing the first substrate and the second substrate, wherein electric power is output when a positional relationship between the electret and the first electrode changes and a positional relationship between the electret and the second electrode changes following a change of relative positions of the first substrate and the second substrate and thereby an electrostatic capacitance between the electret and the first electrode changes and an electrostatic capacitance between the electret and the second electrode changes, wherein a regulating member for making a distance between opposing surfaces of the first substrate and the second substrate constant is provided, wherein the housing is provided with a first reference surface to which the opposing surface of one of the two substrates is fixed, the first reference surface being a positioning reference for positioning the opposing surface of the one substrate in an opposing direction that is perpendicular to the opposing surfaces; and a second reference surface with which the regulating member is slidably in contact, the second reference surface being a positioning reference for positioning the regulating member in the opposing direction, and wherein the regulating member is slidably in contact with the opposing surface of the other of the two substrates.
