摘　　要：采用电路板印制工艺设计了一种基于印制绕组阵列的电磁式能量采集装置,可收集不同转速工况下的旋转机械能,为无线传感节点供电,并且通过蓝牙无线通信方式对传感器信息进行接收与处理。通过将取能线圈的铜导体印制在电路绝缘板上的方式,有效降低了装置的整体质量,实现系统集成化。实验测试结果表明,装置可以实现稳定的三相交流电输出。在400 r/min和1 000 r/min的转速下分别可达到2.24和17.02 mW的峰值功率,经整流、稳压后能够稳定为负载传感器供电。A printed circuit board winding based electromagnetic energy harvesting system is designed in this paper,it can collect rotating mechanical energy under different rotational speed conditions,supply power to wireless sensor nodes,receive and process sensor information through Bluetooth wireless communication.By printing the copper conductor of the energy harvesting coil on the PCB insulation board,the overall quality of the device is effectively improved and the system integration is realized.The experimental results of the electromagnetic energy harvesting system show that the system can achieve stable three-phase AC output.At the speeds of 400 r/min and 1000 r/min,the peak powers of 2.24 mW and 17.02 mW can be reached,respectively,and the power supply for the load sensor can be stably provided after rectification and voltage stabilization.
