Abstract
The invention provides an electrode for an inclination sensor, and belongs to the technical field of sensors. The electrode comprises a cell, and is characterized in that the periphery of the cell is provided with a first coating; the first coating is made of a metal or an oxide thereof; the metal is gold or silver or platinum or rhodium or palladium or cesium. The periphery of the cell material is provided with the coating made of a specific material, so that the oxidation resistance of the electrode can be enhanced, and the electrode is low in corrosion or passivation possibility after being used for a long time; furthermore, the coating formed by methods such as electroplating and electroless plating is capable of greatly reducing the surface roughness of the electrode, so that the influence of electrolyte surface tension on the electrode is less, and the electrode exhibits a hydrophobic characteristic; in such a way, when the sensor inclines, an electrolyte on the electrode breaks away rapidly, so that the electrolyte has low possibility of being attached to the electrode, and thus the sensitivity of the electrode is improved.

Portion has a cavity, simultaneously the certain electrolyte of injection in cavity；It is inserted into several electrodes to liquid after then passing through housing, when
During liquid run-off the straight in housing, the signal of telecommunication on each electrode will change, and then, by recording the change of the signal of telecommunication
Change, you can know angle of inclination now.
However, the electrode in existing obliquity sensor is typically directly made up of corresponding alloy material, the surface of electrode
Typically relatively rough, therefore existing having following defects that for obliquity sensor
A, the rear electrode that works long hours easily are passivated；
B, electrode are easily by corrosion；
C, electrode q value big；
D, electrolyte are liable to stick on electrode, so lead to electrode sensitivity low.

Brief description
Fig. 1 is the Longitudinal cross section schematic of the electrode for obliquity sensor of the present invention；
Fig. 2 is the cross-sectional view of the electrode for obliquity sensor of the present invention；
In figure is labeled as: battery core 11, first coating 12, second coating 13, the 3rd coating 14.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figures 1 and 2, the electrode for obliquity sensor of the present invention, including battery core 11, in battery core 11
Periphery be provided with first coating 12, the material of described first coating 12 is the oxide of a kind of metal or this kind of metal；Its
Described in metal be gold or silver or platinum or rhodium or palladium or caesium.
Wherein, electrode of the present invention is used exclusively for the electrode of obliquity sensor, because in obliquity sensor to electricity
The contact relation of pole and electrolyte require higher, and in order to improve the sensitivity of electrode it is desirable in sensor run-off the straight,
Corresponding signal can be quickly detected；And in order to realize the quick detection of signal, then need connecing of electrode surface and electrolyte
Tactile relation can quickly change with the generation tilting.
The electrode being traditionally used for obliquity sensor is all not provided with coating structure, normally only by corresponding alloy material system
Just directly use after becoming battery core 11, therefore the surface of electrode easily the situation of passivation or corrosion after a long time use,
And the fineness of electrode surface is poor, thus easily adhere to electrolyte, the sensitivity ultimately resulting in traditional electrode is relatively low.
The present invention passes through to arrange the first coating 12 being made up of certain material on the basis of battery core 11, can strengthen electrode
Resistant to rust and resist passivation ability, and further by coating using modes such as plating, chemical plating, evaporation or ion sputterings
One coating 12, can further improve the surface smoothness of electrode, and then it is less that electrode can be made to be affected by electrolyte surface tension force,
The sensitivity of electrode can be improved.In addition, the q value of electrode also can be reduced by arranging coating；Simultaneously also can be by controlling corresponding painting
The impedance to change electrode for the thickness of layer.
In addition, also second coating 13 can be additionally provided between battery core 11 and first coating 12, described second coating 13
Material is nickel or cobalt or nickel cobalt (alloy).The purpose of above-mentioned setting second coating 13 mainly has two, and first is to repair
The defect on battery core 11 surface, to improve effect during coating first coating 12；Second can be prevented from coating first coating 12
When battery core 11 caused corrode.
More specifically, above-mentioned be provided with first coating 12 and second coating 13 when, when first coating 12 select be not
When gold or alloy platinum material, in order to improve the combination effect of first coating 12 and second coating 13 further, can be in first coating 12
3rd coating 14 is set and second coating 13 between, and the material of described 3rd coating 14 is gold or platinum.Certainly, when above-mentioned first
When the material of coating 12 inherently selects gold or platinum, then the 3rd coating 14 can be set.
In addition, generally the present invention battery core 11 can select corresponding according to the difference of the case material of sensor
