Abstract:
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 supplementary stage coupled to the primary stage, the supplementary stage comprising a kinetic energy conversion system to convert motion to stored potential energy, the kinetic energy conversion system comprising: wherein the supplementary stage periodically releases the stored potential energy to generate a resonant oscillation at the first frequency to drive the primary stage, and wherein the first magnet of the resonating electrical generator is diametrically poled and the first biasing element of the resonating electrical generator comprises a torsion shaft with a fixed end, and the resonating electrical generator further comprises a core coupled to and supporting the coil, and wherein the first magnet is coupled to the torsion shaft and configured to rotate as the torsion shaft twists in response to motion.
