Abstract: Embodiments of an energy harvesting and storage system for footwear are described herein. In some embodiments, the system includes a charge generator, such as a permanent magnet movable with respect to a conductive coil to induce an electrical potential, and thus an electric current, in the winding, which can be used to store charge in an electrical energy storage device. The electrical energy storage device can be accessed via an electrical energy access port. Electrical charge can be used by an external device, or electrical charge can be provided by an external source of charge. The components of the energy harvesting and storage system can be disposed in, or coupled to, and article of footwear, such that when a user moves while wearing the article of footwear, charge can be generated and stored for subsequent use.
