The basic working principle of magnetostrictive vibration energy harvesters is described. According to the basic structure and working method of magnetostrictive harvesters, they are classified as the driven-directly and cantilever magnetostrictive vibration energy harvesters. The latest research progresses for the two kinds of harvesters are introduced in detail, their characteristics of the mechanical structure and work are summarized, and their generating performances such as the output voltage, output power, power density and electromechanical conversion efficiency are compared and analyzed. The advantages, disadvantages and applications for the two kinds of harvesters are summarized. Finally, the shortcomings of the current research are further discussed from the energy conversion material, magnetic circuit design, environmental adaptability and miniaturization of the structure for the harvesters. The development trend of the magnetostrictive vibration energy harvesters is also prospected.
