Design Optimization of a Magnetically Levitated Electromagnetic Vibration Energy Harvester for Body Motion

[摘要] This paper presents a magnetically levitated electromagnetic vibration energy harvester based on magnet arrays. It has a nonlinear response that extends the operating bandwidth and enhances the power output of the harvesting device. The harvester is designed to be embedded in a hip prosthesis and harvest energy from low frequency movements (
