This article presents a brief introduction to the dynamics, design, and power optimization of electromagnetic vibration energy harvesters (VEHs), and explains how the power-bandwidth tradeoff of the VEH can be resolved by introducing mechanical nonlinearity, which enables the VEH to be wideband while maintaining its maximum power performance. The well-recognized difficulty of coexisting solution is then described, and the response stabilization control technique proposed by the author is presented as the promising solution of this issue.
