Vibration power generation
First Claim
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.

Abstract
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.
