Patent attributes
A method and device for using magnetostriction to generate electricity from fluid motion. The device includes a first structural component, an outer housing, and a strain structure. The outer housing substantially circumscribes the first structural component and at least partially defines an annular space between the first structural component and the outer housing. The strain structure is coupled within the annular space between the first structural component and the outer housing. The strain structure experiences a change in physical strain imposed by a bearing in response to a relative movement between the bearing and the strain structure. The strain structure includes a magnetostrictive material to generate a magnetic field in response to the change in the physical strain.
