【摘要】：能量采集技术已经成为智能终端领域的一项关键技术,关于人体机械能采集方式也有大量的研究.针对人体机械能采集的应用需求,本文提出一种基于磁悬浮结构的电磁-摩擦复合式能量采集器.该能量采集器以磁悬浮结构作为核心部件,具有结构简单、感应灵敏、输出功率高的优点.在10 MΩ的外接负载时,两组摩擦发电单元输出功率分别为0.12 mW和0.13 mW;在1kΩ外接负载时,两组电磁发电单元的输出功率分别为36 mW和38 mW.复合能量采集器通过电容储能后,电容器可以输出8 V电压,且输出信号为持续的直流信号,可以为计步器提供持续的能量供给,支撑计步器正常工作.设计的复合能量采集器对于可穿戴电子设备自供电工作模式的实现具有重要意义.
[Abstract]:Energy acquisition technology has become a key technology in the field of intelligent terminal. In this paper, a kind of electromagnetic friction composite energy collector based on magnetic levitation structure is proposed. The energy collector takes the magnetic levitation structure as the core component and has the advantages of simple structure and sensitive induction. The output power of the two sets of frictional generation units is 0.12 MW and 0.13 MW respectively when the external load is 10 M 惟, and the output power is 0.12 MW and 0.13 MW when the external load is 1 k 惟, respectively, when the output power is high, the output power is 0.12 MW and 0.13 MW, respectively. The output power of the two sets of electromagnetic generating units is 36 MW and 38 MW respectively. After the composite energy collector stores energy through the capacitor, the capacitor can output 8 V voltage and the output signal is a continuous DC signal. It can provide a continuous energy supply for the pedometer and support the normal operation of the pedometer. The design of the composite energy collector is of great significance to the realization of the self-supply mode of wearable electronic equipment.
