1. A multi-stage system for generating electrical power from motion comprising:
- a primary stage comprising a resonating electrical generator to convert motion to electrical energy, the generator comprising;
a coil;
a first biasing element tuned to resonate at a first frequency; and
a first magnet generating a magnetic field, the first magnet coupled to the first biasing element and disposed in proximity to the coil such that the coil is located within the magnetic field, wherein the first biasing element enables a resonant oscillation of the first magnet, and wherein the resonant oscillation of the first magnet relative to the coil generates an electric current in the coil; and
a supplementary stage coupled to the primary stage, the supplementary stage comprising a kinetic energy conversion system to convert motion to stored potential energy, wherein the kinetic energy conversion system comprises a second biasing element to store potential energy by being forced from a resting position to a tension position, and wherein the second biasing element is tuned to resonate at a second frequency that is lower than the first frequency, andwherein the supplementary stage periodically releases the stored potential energy to generate a resonant oscillation at the first frequency to drive the primary stage.

Abstract
A system for generating electrical energy from ambient motion that comprises two stages, a resonating electrical generator and a kinetic energy conversion system. The different stages have differing resonant frequencies to enable harvesting energy from low frequency ambient motion and converting it to high frequency resonant oscillation for efficiently generating electrical energy.
