Abstract
An apparatus for harvesting energy is described. The apparatus includes a vibration component and a moving mass. The vibration component has a first and second end and further includes a magnetostrictive material. The vibration component further includes a conduction coil wrapped around the magnetostrictive material. The moving mass is coupled to the second end of the vibration assembly. The mass is configured to move in an oscillating path in response to forces acting on the vibration energy harvesting apparatus, inducing strain on the magnetostrictive material. The strain on the magnetostrictive material changes a magnetic property of the magnetostrictive material, inducing electrical energy in the conduction coil wrapped around the magnetostrictive material. Other embodiments of the apparatus are also described.
