Abstract
Embodiments of an apparatus for harvesting electrical power from fluid motion are described. The apparatus includes a magnetostrictive component having an internal pre-stressed magnetostrictive core. A magnetic property of the magnetostrictive core is configured to change with changes in stress within the magnetostrictive core along at least one direction within the magnetostrictive component. Also, forces at least partially due to fluid motion results in changes of stress within the magnetostrictive core and consequently change the magnetic property. The magnetostrictive component is further configured such that the change in the magnetic property will result in a change in the magnetic flux, which can be used to generate electrical power.
