摘要

摘要: 为了提高MEMS电场传感器敏感芯片封装的环境适应性，该文提出一种新型的电极型MEMS电场传感器封装结构。区别于将传感器敏感芯片及探头放置于被测环境中，该文通过在MEMS电场传感器封装管壳外部增加封装电极，仅将封装电极暴露在被测环境中，有效避免了传感器敏感芯片封装管壳受到多种恶劣环境的干扰。研制出基于新型封装结构的MEMS地面电场传感器及探空电场传感器，仿真及试验结果表明，该结构传感器能够实现对电场高精度准确测量，在高湿、低温等恶劣环境下输出稳定可靠。

Abstract: To improve the environmental adaptation of the package of electric field micro sensor, this article introducs a new electrode package. Different from placing the sensing chip and package inside the measured environment, a package electrode, which is the only part exposed outside, is invented. In this way, the package shell is effectively protected from various environmental extremes. Based on this structure, new atmospheric electric field micro sensors are introduced on the ground and for sounding. The FEM and experiments show that the new sensors measure electric field accurately and stably under high humidity and low temperature environment.
