Embodiment

[0038] like Figure 1 to Figure 3 As shown, a miniature electric field sensor includes:

[0039] The sensing electrode 2, which includes a first sensing electrode plate and a second sensing electrode plate that are disposed oppositely and isolated, is a comb-like structure;

[0040] Shielding electrode 1, its comb-like structure must be able to completely shield the comb-like structure of sensing electrode 2, and each part of the comb-like structure of shielding electrode 1 and the comb-like structure of sensing electrode 2 are arranged in a staggered manner;

[0041] The shielding electrodes 1 are supported and insulated by insulating pillars 3 ; the sensing electrodes 2 are insulated from each other by insulating pillars 3 . The insulating pillars 3 are distributed on both sides around the substrate base.

[0042] The electrode plates of the induction electrodes 2 are all made of stainless steel.

Abstract

The invention discloses a miniature electric field sensor. The miniature electric field sensor comprises a substrate; at least one electric field measuring unit is arranged in the X direction, the Y direction and the Z direction of the substrate, the electric field measuring unit comprises a shielding electrode and an induction electrode, and the shielding electrode moves relative to the induction electrode so that alternating current can be generated on the induction electrode. The three-dimensional electromagnetic field sensor has single-value input and output characteristics, can measure the electromagnetic field intensity at the same time, and is simple in structure, small in size, low in cost, good in linearity, high in accuracy and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of micro sensor manufacturing, in particular to a micro electric field sensor. Background technique [0002] With the increasing tension of line corridors, the environmental impact of power transmission and transformation projects has also become an important factor that must be considered in the process of project planning, feasibility study, design, construction and operation. key constraints. With the rapid development of urban and rural construction and the continuous expansion of urban scale, the impact of power transmission and transformation projects on nearby residential buildings and various environmentally sensitive areas has become increasingly prominent, and complaints about the environmental impact of the power grid are increasing. Expenditures have been rising year by year, affecting the company's economic benefits. [0003] One of the main complaints of residents near transmission lines is t...
