Abstract:
1. A device for energy harvesting from motion of an object, the device comprising: at least one magnet; at least one coil; a magnet supporting structure supporting the at least one magnet; a coil supporting structure supporting the at least one coil, wherein the magnet supporting structure and the coil supporting structure have a fixed relative orientation when the object is not in operation and enable relative movement between the at least one magnet and the at least one coil during operation of the object, and wherein at least one of the magnet supporting structure or the coil supporting structure is configured to be affixed to the object; and means for providing a restoring force to at least one of: the magnet supporting structure or the coil supporting structure, wherein the restoring force reduces the relative movement and causes at least one of: the magnet supporting structure or the coil supporting structure to move toward the fixed relative orientation during operation of the object.
