Abstract
A vibration based power generator. In a described embodiment, an electrical power generating system includes a vibrating assembly including a vortex shedding device which sheds vortices in response to fluid flow across the vibrating assembly. A generator generates electrical power in response to vibration of the vibrating assembly. The vortex shedding device sheds the vortices at a frequency which is substantially equal to a resonant frequency of the vibrating assembly.

An electrical power generating system, comprising:
- a vibrating assembly including a vortex shedding device which sheds vortices in response to fluid flow across the vibrating assembly;
- and
- a generator which generates electrical power in response to vibration of the vibrating assembly, wherein the vortex shedding device sheds the vortices at a frequency which is substantially equal to a resonant frequency of the vibrating assembly.
An electrical power generating system, comprising:
- a vibrating assembly including a vortex shedding device which sheds vortices in response to fluid flow across the vibrating assembly;
- and
- a generator which generates electrical power in response to vibration of the vibrating assembly,
- wherein the vortex shedding device sheds the vortices at a frequency which is substantially equal to a resonant frequency of the vibrating assembly, and
- wherein the generator includes an electromagnetically active material in which strain is induced in response to vibration of the vibrating assembly.
An electrical power generating system, comprising:
- a vibrating assembly including a vortex shedding device which sheds vortices in response to fluid flow across the vibrating assembly;
- and
- a generator which generates electrical power in response to vibration of the vibrating assembly,
- wherein the vortex shedding device sheds the vortices at a frequency which is substantially equal to a resonant frequency of the vibrating assembly, and
- wherein the generator includes an electromagnetically active material attached to a beam of the vibrating assembly, so that strain in the beam is transmitted to the material, and electricity is produced in response to the strain in the material.
An electrical power generating system, comprising:
