Abstract

A system for harvesting electrical energy from the vibration or movement of a portable electronic device. The portable electronic device is attached to a spring anchored to a supporting housing. This forms a spring-mass system with the portable device acting as the majority of the mass of the energy harvester and oscillating with respect to the housing. The oscillation is coupled to an electrical energy transduction mechanism which harvests some of the kinetic energy of the oscillation. The object of the invention is to provide maximum harvested energy without adding additional mass to the portable device other than the spring, supporting housing, energy transduction mechanism and any associated electronics.
