    This paper presents a novel design of a magnetically-sprung mechanical resonator for wideband vibration energy harvesting. In this design, a magnet composite consisting of two cylindrical magnets composed in a repelling arrangement is used as a moving mass, which is magnetically suspended between two ring magnets. This configuration yields more significant variation of stiffness in a shorter stroke compared with the previous design, resulting in wider operation band even under small excitation.
