This paper presents a novel atmospheric electric field sensor based on high sensitivity resonant MEMS (microelectromechanical systems) electric field sense chips, which resolves the problems of motor wear, high power consumption and failure rate of the conventional electric field mill. The chip was fabricated in a commercial SOIMUMPS process. The sensor overall structure scheme was proposed and the...
We have developed a highly sensitive electric-field sensor with novel comb-shaped microelectrodes. The sensor is based on modulating an incident field with a grounded shutter and measuring the induced charge of sensing electrodes. Owing to the shutter covering the side wall of the sensing electrodes, the fringing fields are no longer a factor that reduces the performance of the sensor. Moreover, in...
The paper presented a novel MEMS (Microelectro-mechanicalsystems) electric field sensor (EFS) based on SOI (Silicon on Insulator) fabrication process for detecting internal defect of non-ceramic (composite) insulators. The ability to measure both AC and DC electric field is a significant advantage of this sensor in comparison to other sensors, which can only measure either AC or DC electric field...
This paper presented a novel resonant electric field sensor (EFS) based on SOI fabrication process for power engineering applications. The sensor architecture has three major blocks: a vibration shutter, sensing electrodes, and a driving electrode that feeds back to the shutter. The EFS structure is designed to work at resonant frequency for maximum sensitivity to electric fields. Prototyped by the...
