基于磁弹簧的电动交通传感器电磁能量采集器理论建模：分析、优化与实验验证

Traditional electromagnetic vibration energy harvesters (EMVEHs) typically exhibit a low output power and operate at a single frequency. As a result, they are only capable of harvesting energy at a specific frequency from the environment, which hinders further application of EMVEHs in practice. To address this vital problem, this article proposes an enhanced magnetic spring-based EMVEH, which uses...
