In：Including platform, microelectrode, two wires and capacitance detecting instrument, the microelectrode is arranged on platform, and the of two wires
One end is connected to the two ends of microelectrode respectively by conducting resinl, and the second end of two wires is connected to the capacitance detecting instrument
With the capacitance of detection microelectrode on table.
In order to easy to connect, the two ends of the microelectrode are coated with conductive metal sheet, the first end of two wires respectively
It is connected respectively on two conductive metal sheets by conducting resinl.
Selectively, the conductive metal sheet is the sheet metal that the plating of gold, silver, zinc, aluminium or copper product is in.
Preferably, the conducting resinl is conductive silver glue.

Compared with prior art, the utility model has the advantage of：The microelectrode detection means is in the electric capacity to microelectrode
When value is detected, the capacitance of microelectrode is easily obtained by only need to be connected to wire on capacitance detecting table, compared to
Need to hold in prior art the test pencil point by universal meter to be detected at the two ends of microelectrode, the microelectrode detection means is using leading
Line capacitance detection table causes to connect contact more preferably, and electric conductivity is more preferable, and more convenient to operate, and the capacitance for obtaining is more
Stable accurate.In addition the microelectrode detection means also facilitates by the apparent microelectrode of examining of capacitance detecting in different dielectric material conditions
Under change, and then the convenient sensitivity parameter for obtaining microelectrode.
Description of the drawings
Fig. 1 is the structural representation of microelectrode detection means in the utility model embodiment one.
Fig. 2 is the structural representation of microelectrode detection means in the utility model embodiment two.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Embodiment one
As shown in figure 1, the microelectrode detection means in the present embodiment, including platform 1,2, two wires 3 of microelectrode and electricity
Hold instrumentation 5.
Platform 1 in the present embodiment is slide, and microelectrode 2 is encapsulated on the slide, the first end point of two wires 3
Not Tong Guo conducting resinl 4 be connected to the two ends of microelectrode 2, the conducting resinl 4 uses conductive silver glue, as conductive silver glue has low electricity
Resistance, hardness is good, tack is good, solidify firm the advantages of with ensure microelectrode 2 and wire 3 good be conductively connected relation.Two
Second end of wire 3 is connected in capacitance detecting instrument 5 to detect the capacitance of microelectrode 2.The capacitance detecting instrument 5 is
Universal meter.
2 detection process of microelectrode is as follows：1st, wire 3 is placed on 2 two ends of microelectrode, then conductive silver glue is applied to wire 3
With the two ends of microelectrode 2 so that wire 3 is bonding with the end of microelectrode 2, uniform when conductive silver glue is smeared, conductive silver glue
Should not be excessively also unsuitable very few, the influence factor for solidifying and increased measurement is excessively difficult, is solidified at least excessively not firm enough.
2nd, 2 sample of microelectrode is placed on where not being destroyed safely, is waited after allowing within 4-5 days which to be fully cured, after solidification
Conductive silver glue construction intensive and have a good case hardness, this kind of construction gives good electric conductivity and wear-resistant
Property, the adhesive force of fabulous elasticity and brilliance causes wire 3 to solidify firmly.
3rd, an inspection is done either with or without impaired to solidification situation and microelectrode 2 using universal meter, checks wire 3 and microelectrode
Whether 2 two ends turn on, and microelectrode 2 is either with or without impaired because solidifying work.
4th, after in step 3, every content detection is normal, the second end of two wires 3 is connected on universal meter,
The capacitance under air of microelectrode 2 is measured with universal meter.Then drip upper different dielectric material again on microelectrode 2, and see
