A system, method, and apparatus for kinetic energy harvesting are disclosed. An example kinetic energy harvesting apparatus includes first and second magnet housings configured to each have a tubular shape. Each of the first and second magnet housing contains a central magnet and a ferrous shield connected to the respective magnet housings. One of the ferrous shields is located on a first side of the first magnet housing that is opposite of a second side facing the second magnet housing. The other of the ferrous shields is located on a first side of the second magnet housing that is opposite of a second side facing the first magnet housing.
