摘　　要：为了解决传统化学电池无法为无线传感网络持久供能的问题,设计了一种高效转换低频振动能的磁悬浮基电磁-摩擦电混合能量收集器,利用磁悬浮系统感应低频环境振动,通过电磁-摩擦电复合能量转换机制高效提取振动能量。研究了平面弹簧刚度和激励加速度对混合能量收集器输出性能的影响,实验结果表明,输出电压随平面弹簧刚度的增大而降低,随激励加速度的增大而增大,当平面弹簧刚度为562 N/m、激励加速度为1.2g时,电磁能量收集单元(EMG)、摩擦电能量收集单元Ⅰ(TENGⅠ)和摩擦电能量收集单元Ⅱ(TENGⅡ)的最大输出峰峰值电压分别为1.15、53、167 V。In order to solve the problem that traditional chemical batteries cannot provide sustained energy for wireless sensor networks,an electromagnetic-triboelectric hybrid energy collector based on maglev system was designed,which can convert low-frequency vibration energy efficiently.The maglev system was used to induce low-frequency environmental vibration,and the vi-bration energy was efficiently extracted through the electromagnetic-triboelectric composite energy conversion mechanism.The in-fluence of planar spring stiffness and excitation acceleration on the output performance of a hybrid energy harvester was analyzed.The experimental results prove that the output voltage decreases with the increase of planar spring stiffness and increases with the increase of excitation acceleration.The maximum peak-to-peak output voltages of the electromagnetic energy harvesting unit(EMG),triboelectric energy harvesting unitⅠ(TENGⅠ),and triboelectric energy harvesting unitⅡ(TENGⅡ)were 1.15、53、167 V respectively under a planar spring stiffness of 562 N/m and an excitation acceleration of 1.2g.
