Abstract
A power generator (200) that provides power to a portable device has a housing that is subject to external motion. The power generator has a first member (218) comprising an electrical component (224) and a second member (210) comprising a magnetic component (220) movable relative to the electrical component such that an electromagnetic interaction between the electrical and magnetic components generates an electrical current in the electrical component. The electrical current can be used as a charge current, for example, for charging one or more batteries. A spring element (228) coupled to at least one of the first and second members defines a spring-mass system that is responsive to the external motion for moving the first member and second member relative to each other along a movement axis. The electrical component comprises a coil having one or more windings around a coil axis that is substantially perpendicular to the movement axis.
