초록 ▼

Vibration-based electrical power generation is provided. In one aspect, a vibration-based power generator is embodied within a machine dampener and includes an electromotive power generation module and a piezoelectric power generation module. A power storage device is operably coupled to the electromotive power generation module and the piezoelectric power generation module. In another aspect, a device for generating electrical energy based is provided. The device includes a housing operably coupleable to a source of vibration. The housing defines a chamber inside. A first circular permanent magnet is located within the chamber and has an outer diameter. A ring-type permanent magnet is located around the first circular permanent magnet and defines an annular space therebetween. At least one voice coil portion is located in the annular space and is coupled to a flexure structure to allow the voice coil portion(s) to move within the flux of the permanent magnets in response to vibration.

What is claimed is: 1. A hybrid vibration-based power generator comprising: an electromotive power generation module; a second power generation module, that converts power differently than the electromotive power generation module; a power storage device operably coupled to the electromotive power generation module and the second power generation module; and wherein the device is embodied within a machine dampener. 2. The device of claim 1, wherein the device is embodied within a piston-type machine dampener. 3. The device of claim 1, wherein the device is embodied within a bar-type machine dampener. 4. The device of claim 1 and further comprising an additive electrical circuit interposed between the power storage device and the generation modules, wherein the additive electrical circuit is configured to provide an additive signal to the power storage device. 5. The device of claim 4, and further comprising a step-up voltage converter disposed between the additive electrical circuit and the power storage device. 6. The device of claim 1, wherein the device is configured to provide an indication relative to a characteristic of vibration. 7. The device of claim 6, wherein the indication is also a diagnostic indication relative to a source of vibration. 8. The device of claim 6, wherein the characteristic is amplitude. 9. The device of claim 6, wherein the characteristic is frequency. 10. The device of claim 1, wherein the second generation module is a piezoelectric generation module. 11. The device of claim 1, wherein the second generation module is a thermal generation module. 12. The device of claim 1, wherein the machine dampener couples a vibration source to a floor. 13. The device of claim 1, wherein a power-up threshold is associated with the power storage device. 14. The device of claim 13, wherein an attached device is selectively powered up based at least in part upon the power-up threshold. 15. The device of claim 14, wherein the power-up threshold is based at least in part upon an amount of stored energy. 16. The device of claim 14, wherein the power-up threshold is based at least in part upon a pre-selected amount of time.
