“…From the aspects of material and structure [17][18][19][20][21], the researchers have improved the one-dimensional to threedimensional AEFA. Among them, Wen et al [19] proposed a three-dimensional measurement method based on coplanar decoupling structure to solve the coupling problem between 3D atmospheric electric field components. Xu et al [20] used particle swarm optimization (PSO) and 3D atmospheric electric field to invert the thunderstorm clouds and analyzed the electric field variation during a thunderstorm.…”

The relationship between smart devices and human beings is one of the research hotspots of the Fourth Industrial Revolution (4IR). In this regard, we explored the practical relationship between the 3D electric field components measured by the smart 3D atmospheric electric field apparatus (AEFA) and the thunderstorm activity from the perspective of the observer. Especially, in the application of AEFA, a smart calibration method is proposed to solve the problem of inconvenient thunderstorm data acquisition. Firstly, in order to obtain the thunderstorm charge position from the observation angle of the apparatus, this paper establishes a 3D electric field measurement model. According to the mirror method theory, we further obtain the charge potential distribution at AEFA. Then, the electric field components are derived by using the potential distribution formula with permittivity. In addition, based on the vector relation of the model, the thunderstorm charge azimuth and elevation angles are obtained. Finally, after the establishment of a new coordinate system, the calibration of charge localization is carried out, based on the observation point. Meanwhile, a preliminary solution is given to the problem that the elevation of the apparatus position affects the localization performance. Results show that the method matches the data of radar map and microphone array, which reflects the advantages of the method. Besides, this method can be used not only in sound source localization but also in AI thunderstorm monitoring system to realize a big data net observation.

“…Aimed at developing MEMS-based 3D EFSs with low cross-axis coupling interference, some relevant works have been reported concerning algorithms and novel micromachined sensor structures. Wen [ 19 ] firstly derived a 3 × 3 coupling sensitivity matrix with pre-measured cross-axis sensitivities, and employed this matrix to compensate the measurement results from three typical one-dimensional (1D) EFSCs. Li [ 20 ] introduced a genetic algorithm (GA) to determine the coupling sensitivity matrix.…”

One of the major concerns in the development of three-dimensional (3D) electric field sensors (EFSs) is their susceptibility to cross-axis coupling interference. The output signal for each sensing axis of a 3D EFS is often coupled by electric field components from the two other orthogonal sensing axes. In this paper, a one-dimensional (1D) electric field sensor chip (EFSC) with low cross-axis coupling interference is presented. It is designed to be symmetrical, forming a pair of in-plane symmetrically-located sensing structures. Using a difference circuit, the 1D EFSC is capable of sensing parallel electric fields along symmetrical structures and eliminating cross-axis coupling interference, which is contrast to previously reported 1D EFSCs designed for perpendicular electric field component measurement. Thus, a 3D EFS with low cross-axis coupling interference can be realized using three proposed 1D EFSCs. This 3D EFS has the advantages of low cross-axis coupling interference, small size, and high integration. The testing and calibration systems of the proposed 3D EFS were developed. Experimental results show that in the range of 0–120 kV/m, cross-axis sensitivities are within 5.48%, and the total measurement errors of this 3D EFS are within 6.16%.

“…Wang et al [20] introduced a biaxial MEFS that can sense an in-plane electrostatic field but has no axis to sense the vertical component; the author asserted that monolithic 2D or 3D MEFSs require high structural integrity and an accurate decoupling calibration method. By deriving a coupling sensitivity matrix, Wen et al [23] and Fang et al [24] distributed three 1D MEFSs in-plane and orthogonally to measure a 3D electrostatic field. In their studies, the elimination of coupling interference among the three components of the electrostatic field simply relied on an algorithm instead of the structural design.…”

This paper presents a single-chip 3D electric field microsensor, in which a sensing element is set at the center to detect the Z-axis component of an electrostatic field. Two pairs of sensing elements with the same structure are arranged in a cross-like configuration to measure the X-and Y-axis electrostatic field components. An in-plane rotary mechanism is used in the microsensor to detect the X-, Y-, and Z-axis electrostatic field components simultaneously. The proposed microsensor is compact and presents high integration. The microsensor is fabricated through a MetalMUMPS process. Experimental results show that in the range of 0-50 kV/m, the linearity errors of the microsensor are within 5.5%, and the total measurement errors of the three electrostatic field components are less than 14.04%.
