Abstract
A system for generating electrical energy from ambient energy such as the energy of ambient motion and acoustic vibrations. The system has at least two stages, a resonating electrical generator and a kinetic energy conversion system. The stages have differing resonant frequencies to enable harvesting energy from lower frequency ambient motion and converting the energy to higher frequency resonant oscillation for efficiently generating electrical energy. A multiaxial system having a plurality of systems for generating electrical energy from ambient motion each oriented to be responsive to motion along a different axis. An embodiment of a system for generating electrical energy from ambient motion for which the resonating electrical generator is at least part of a driving mass of the kinetic energy conversion system.
