摘　　要：针对探测海洋极低频电场对于传感器灵敏度要求高的特点,提出一种新型的电场传感器结构设计方案。基于海洋电场放大效应,开展传感器结构设计仿真研究,通过引入拓扑优化和形状优化的方法提高被测电场幅度,提升电场传感器的灵敏度。仿真结果表明:结构设计后的海洋电场传感器相比无壳体传感器,灵敏度提高了2.28倍。In view of the high requirements for sensor sensitivity in detecting marine extremely low frequency electric fields,a new electric field sensor structure design scheme is proposed.Based on the amplification effect of marine electric fields,this study conducts simulation research on sensor structure design,and improves the amplitude of the measured electric field and the sensitivity of the electric field sensor by introducing topology optimization and shape optimization methods.The simulation results show that the sensitivity of the marine electric field sensor after structural design is 2.28 times higher than that of the sensor without a shell.
