摘要： In a vibration power generator that generates power by relatively moving an electret and an electrode in a state in which the electret and the electrode oppose each other, a gap between the electret and the electrode is suitably formed. In the vibration power generator in which an electret group and an electrode group are provided in a movable member and a fixed member and vibration power generation is performed by displacement of both of the members in a relative movement direction by an external vibration, the electret group and the electrode group are accommodated in a housing portion. In addition, the vibration power generator includes a plurality of support members that are disposed so as to be slidable on the fixed member, are interposed directly between the fixed member and the movable member so as to define a gap between a fixed member-side power generation element and a movable member-side power generation member, and support the movable member so as to allow relative movement of the movable member with respect to the fixed member. Slide surfaces on which the plurality of support members slide are formed on a common substrate surface of a substrate of the fixed member.

摘要： A circuit-based technique enhances the power output of electrostatic generators employing an array of axially oriented rods or tubes or azimuthal corrugated metal surfaces for their electrodes. During generator operation, the peak voltage across the electrodes occurs at an azimuthal position that is intermediate between the position of minimum gap and maximum gap. If this position is also close to the azimuthal angle where the rate of change of capacity is a maximum, then the highest rf power output possible for a given maximum allowable voltage at the minimum gap can be attained. This rf power output is then coupled to the generator load through a coupling condenser that prevents suppression of the dc charging potential by conduction through the load. Optimized circuit values produce phase shifts in the rf output voltage that allow higher power output to occur at the same voltage limit at the minimum gap position.
