Abstract
A vibration power generation device that further improves power generation efficiency includes a vibration exciting body in which vibration is caused by a flowing fluid, a vibrated body that is oscillatable and connected to the vibration exciting body, and a power generator to generate electricity by oscillation of the vibrated body. The vibration exciting body is in proximity to a wall surface, and vibration is caused in the vibration exciting body by a fluid flowing along the wall surface.
Claims25
A vibration power generation device comprising:
- a vibration exciting body in which vibration is caused by a flowing fluid;
- a vibrated body that is oscillatable and connected to the vibration exciting body;
- and
- a power generator to generate electricity by oscillation of the vibrated body;
- wherein
- the vibration exciting body is located in proximity to a wall surface, and vibration is caused in the vibration exciting body by a fluid flowing along the wall surface;
- and
- a length L of the vibration exciting body in a direction parallel to the wall surface and perpendicular to a direction of the fluid flow is more than 3 times a length H of the vibration exciting body in a direction perpendicular to the wall surface.
A moving object comprising:
- a surface in contact with a fluid;
- and
- a vibration power generation device located on the surface and including:
- a vibration exciting body in which vibration is caused by the fluid;
