Problems solved by technology

[0003] However, in other generators, when the first substrate and the second substrate are vibrated, the amount of relative movement between the substrates is limited by the portion where the first substrate and the second substrate are electrically connected via a load.
Therefore, since the increase or decrease of the area of ​​the electret film that moves relative to the electrodes is restricted, there is a problem that it is difficult to improve the power generation efficiency of the generator.
That is, there is a problem that it is difficult to improve the conversion efficiency of kinetic energy and electric energy in other electrostatic devices such as generators.
