| 摘 要： | 该文研制了一种新型的基于SOI(Silicon-On-Insulator)微机械加工技术的高性能电场传感器敏感结构。为提高传感器的灵敏度和信噪比,该器件采用侧面屏蔽感应电极的独特设计方案,降低了传感器屏蔽电极的边缘效应;并基于有限元仿真,进一步优化了传感器敏感结构参数。在室温和室内大气压条件下,测试表明,测试量程0～50kV/m,传感器总不确定度优于2%,分辨率为50 V/m。

| Abstract: | A novel and high-performance electric field microsensor is presented based on Silicon-On-Insulator(SOI) fabrication technology.In order to improve the sensitivity and SNR(Signal to Noise Ratio) of the sensor,the unique design of the shutter covering the side wall of the sensing electrodes is used,which reduces the effect of fringing fields of the shutter.Moreover,the electrode structure parameters of the sensor are optimized by Finite Element Simulation(FES).It is found that the new sensor had a resolution ... |
