Description

Technical Field

[0001] This application relates to the technical field of electrochemical measurement electrodes, and particularly to a screen-printed electrode and a method for detecting the insulation performance of a screen-printed electrode. Background Art

[0002] An electrochemical electrode is one of the most important components of an electrochemical analysis method. The analyte undergoes a biochemical reaction on the electrode surface, causing relevant electrochemical signal (voltage signal, current signal, resistance signal, etc.) changes in the electrode, thereby establishing a qualitative and quantitative analysis method for the analyte and realizing the detection of the analyte. The most widely used electrochemical electrode is the screen-printed electrode. Through the form of screen printing, multiple electrodes of traditional electrochemistry are printed on the same plane, thereby preparing sensing electrodes of various shapes and styles.

[0003] However, when printing multiple electrodes on a substrate, at least two of them need to be printed on the same side of the substrate. To enable a multi-electrode system including multiple electrodes to work properly, an insulating layer needs to be printed between at least two electrodes on the same side of the substrate to avoid short circuits. However, whether the insulating layer has achieved good insulation performance usually requires further testing. Existing methods usually use a multimeter to touch the corresponding electrodes to test whether the two electrodes are insulated, which can only achieve point detection of the insulation performance of the insulating layer and cannot achieve large-area detection of the insulation performance of the insulating layer.

[0042] In this embodiment, a screen-printed electrode is further provided. Figure 1 It is a schematic structural diagram of a screen-printed electrode according to an embodiment of this application, as Figure 1As shown, the screen-printed electrode includes: a substrate 10, a first electrode 20, a second electrode 30, and a first insulating layer 50. The first electrode 20, the first insulating layer 50, and the second electrode 30 are sequentially printed on one side of the substrate 10; the first electrode 20 includes a first substance 70, and the second electrode 30 includes a second substance 60. Among them, when irradiated by a first target light 80, a second target light 90 is generated on the surface of the second electrode 30. When the first substance 70 and the second substance 60 come into contact, the intensity of the second target light 90 changes; the second target light 90 is used to detect the performance of the first insulating layer 50. Specifically, the first insulating layer 50 is disposed between the first electrode 20 and the second electrode 30. The paste of the first electrode 20 is coated on one side of the substrate 10 by screen printing, the paste of the first insulating layer 50 is coated on one side of the first electrode 20 by screen printing, and the paste of the second electrode 30 is coated on one side of the first insulating layer 50 by screen printing. When preparing the pastes of the first electrode 20 and the second electrode 30, the first substance 70 is uniformly mixed in the original paste of the first electrode 20 to obtain the paste of the first electrode 20, and the second substance 60 is uniformly mixed in the original paste of the second electrode 30 to obtain the paste of the first electrode 20, so that the first electrode 20 includes the first substance 70 and the second electrode 30 includes the second substance 60. When the surface of the second electrode 30 is irradiated with the first target light 80 and the first substance 70 and the second substance 60 come into contact, a second target light 90 will be generated on the surface of the second electrode 30. By detecting the intensity and wavelength of the second target light 90, the performance of the first insulating layer 50 can be detected. When the first insulating layer 50 fails to perform the insulation function, at this time, the first electrode 20 and the second electrode 30 will come into contact, resulting in a short circuit between the first electrode 20 and the second electrode 30. At this time, a chemical reaction occurs when the first substance 70 and the second substance 60 come into contact. Under the irradiation of the first target light 80, a second target light 90 will be generated.

The excitation light can be determined according to the excitation wavelength of the first substance 70, or according to the excitation wavelength of the second substance 60, or according to the excitation wavelength of the substance generated after the chemical reaction between the first substance 70 and the second substance 60. No specific limitation is made here.

[0043] Specifically, the second substance 60 will generate a second target light 90 on the surface of the second electrode 30 under the irradiation of the first target light 80. When the first substance 70 and the second substance 60 come into contact, the second target light 90 generated under the irradiation of the first target light 80 will gradually weaken until it disappears. By detecting the intensity and wavelength of the second target light 90, it is determined whether the first substance 70 and the second substance 60 are in contact. By determining whether the first substance 70 and the second substance 60 are in contact, it is determined whether the first electrode 20 and the second electrode 30 are short-circuited. By determining whether the first electrode 20 and the second electrode 30 are short-circuited, it is determined whether the first insulating layer 50 is working properly, that is, the performance of the first insulating layer 50 is detected by determining whether the first electrode 20 and the second electrode 30 are short-circuited. By detecting the position and intensity of the second target light 90 over a large range, the insulating performance of the first insulating layer 50 over a large range can be realized.

[0060] It should be noted that the substances in the electrodes on the same side of the substrate can be interchanged. For example, the second substance 60 can be included in the first electrode 20, the first substance 70 can be included in the second electrode 30, the second substance 60 can be included in the third electrode 40, and the first substance 70 can be included in the fourth electrode 41.

[0062] In this embodiment, by respectively arranging a first substance 70 in the first electrode 20 and a second substance 60 in the second electrode 30, under the irradiation of the first target light 80, a second target light 90 will be generated on the surface of the second electrode 30.

By judging whether the first substance 70 and the second substance 60 are in contact, it is determined whether the first electrode 20 and the second electrode 30 are short-circuited. By judging whether the first electrode 20 and the second electrode 30 are short-circuited, it is judged whether the first insulating layer 50 is working normally, so as to realize the detection of the insulation performance of the first insulating layer 50 of the screen-printed electrode in a large range; by respectively arranging a first substance 70 in the third electrode 40 and a second substance 60 in the fourth electrode 41, under the irradiation of the first target light 80, a second target light 90 will be generated on the surface of the fourth electrode 41. By detecting the wavelength and intensity of the second target light 90, it is judged whether the first substance 70 and the second substance 60 are in contact. By judging whether the first substance 70 and the second substance 60 are in contact, it is determined whether the third electrode 40 and the fourth electrode 41 are short-circuited.

[0063] Hereinafter, an example will be given in which the first substance 70 is a reactant that can chemically react with a compound to generate the second target light 90, and the second substance 60 is a compound, and the screen-printed electrode includes three electrodes.

[0064] To test the performance of the first insulating layer 50, a first substance 70 and a second substance 60 are respectively added to the original slurries of the first electrode 20 and the second electrode 30. According to requirements, appropriate first substance 70 and second substance 60 can be selected so that when they are well isolated by the first insulating layer 50, they emit a kind of fluorescence or do not emit fluorescence under the irradiation of the first target light 80; while if the first insulating layer 50 fails to work properly and causes a short circuit between the first electrode 20 and the second electrode 30, the first substance 70 and the second substance 60 will undergo a chemical reaction, resulting in a change in their fluorescence state, and another fluorescence signal will be emitted under the irradiation of the first target light 80. After the screen-printed electrodes are printed, they can be placed under a fluorescence microscope for fluorescence detection, so as to achieve large-scale, rapid, and non-contact insulation detection.

[0065] Figure 4 It is a schematic diagram of a chemical reaction between the second substance 60 and the first substance 70 to generate a second target light 90. As Figure 4 shown, the second substance 60 includes a first group 601 and a second group 602. In this embodiment, the second target light 90 is the second fluorescence 902. There is fluorescence resonance energy transfer FRET or other mechanisms that may cause fluorescence quenching between the first group 601 and the second group 602, resulting in the second substance 60 emitting the first fluorescence 901 under the irradiation of the first target light 80. When the first substance 70 comes into contact with the second substance 60 and undergoes a chemical reaction, the second substance 60 decomposes into the first group 601 and the second group 602. At this time, under the irradiation of the first target light 80, the second fluorescence 902 will be generated, and the intensity of the first fluorescence 901 will gradually weaken until it disappears. By detecting the intensity and position of the first fluorescence 901, or by detecting the fluorescence signal intensity and position of the second fluorescence 902, the short-circuit situation between the first electrode 20 and the second electrode 30 can be indirectly obtained.

[0066] Figure 5 It is another schematic diagram of a chemical reaction between the second substance 60 and the first substance 70 to generate a second target light 90. As Figure 5 shown, the second substance 60 includes a third group 603. In this embodiment, the second target light 90 is the third fluorescence 903. The third group 603 does not emit fluorescence under the irradiation of the first target light 80 due to the presence of a blocking group. When the second substance 60 comes into contact with the first substance 70 and undergoes a chemical reaction, the blocking group is removed to obtain a fourth group 604, and the fourth group 604 emits the third fluorescence 903 under the irradiation of the first target light 80. By detecting the fluorescence signal intensity of the third fluorescence 903, the short-circuit situation between the first electrode 20 and the second electrode 30 can be indirectly obtained.

[0067] Figure 6It is a schematic diagram of another chemical reaction between the second substance 60 and the first substance 70 to generate the second target light 90. As Figure 6 shown, the second substance 60 includes a fifth group 605. In this embodiment, the second target light 90 is the fourth fluorescence 904, and the fifth group 605 does not fluoresce under the irradiation of the first target light 80. When the second substance 60 contacts the first substance 70 and thus a chemical reaction occurs, the reactant combines with the fifth group 605 to form a sixth group 606, and the sixth group 606 emits the fourth fluorescence 904 under the irradiation of the first target light 80. By detecting the fluorescence signal intensity of the fourth fluorescence 904, the short - circuit condition of the first electrode 20 and the second electrode 30 can be indirectly obtained. The first fluorescence 901, the second fluorescence 902, the third fluorescence 903, and the fourth fluorescence 904 can be distinguished by the wavelength of the collected fluorescence signal. The first fluorescence 901, the second fluorescence 902, the third fluorescence 903, and the fourth fluorescence 904 are all forms of the second target light 90.

[0068] By adding different fluorophores to the printing pastes of different electrodes, non - contact insulation detection is achieved; according to the selection of the fluorophore, simultaneous detection of whether multiple electrodes are conducting can be realized; during the screen - printing electrode printing process, the printing effect of the first insulating layer 50 can be monitored in real time. By quantitatively analyzing the fluorescence signal, the effect of the first insulating layer 50 can be viewed in real time. Further, the thickness of the first insulating layer 50 can be monitored in real time, so as to achieve the best insulating effect with the least amount of the first insulating layer 50.

[0069] In this embodiment, a method for detecting the insulation performance of a screen - printed electrode is provided. Figure 7 It is a flowchart of a method for detecting the insulation performance of a screen - printed electrode according to an embodiment of the present application. This detection method is used to detect the screen - printed electrode described in the foregoing embodiment. As Figure 7 shown, this process includes the following steps:

[0070] Step S510, determine whether the first insulating layer 50 is abnormal according to the intensity and wavelength of the second target light 90; the second target light 90 is the light generated on the surface of the second electrode 30 when the screen - printed electrode is irradiated by the first target light 80.

[0071] Specifically, obtain the wavelength of the second target light 90, which is collected by a microscope. When the wavelength of the second target light 90 is the target wavelength and the intensity of the second target light 90 and the threshold value meet the preset conditions, it is determined that the first insulating layer 50 is abnormal. The preset conditions here can be that the intensity of the second target light 90 is greater than the threshold value or the intensity of the second target light 90 is less than the threshold value. By detecting the wavelength of the second target light 90 and the intensity of the second target light 90, the short - circuit condition between the first electrode 20 and the second electrode 30 can be indirectly obtained, thereby determining whether there is an abnormality in the first insulating layer 50. The second target light 90 is the light generated on the surface of the second electrode 30 when the screen - printed electrode is irradiated by the first target light 80. When the first substance 70 and the second substance 60 are in contact, the intensity of the second target light 90 can become stronger or weaker. When the first substance 70 and the second substance 60 are different, the wavelengths of the generated second target light 90 are also different. Determine the target wavelength based on the structure or properties of the first substance 70 and the second substance 60.

[0072] Step S520: When the first insulating layer 50 is abnormal, determine the abnormal position of the first insulating layer 50 according to the position of the second target light 90.

[0073] Specifically, when the wavelength of the second target light 90 is the first target wavelength and the intensity of the second target light 90 is greater than the threshold value, after determining that the first insulating layer 50 is abnormal, determine the abnormal position of the first insulating layer 50 according to the position where the second target light 90 is generated on the surface of the second electrode 30. Or, when the wavelength of the second target light 90 is the second target wavelength and the intensity of the second target light 90 is less than the threshold value, after determining that the first insulating layer 50 is abnormal, determine the abnormal position of the first insulating layer 50 according to the position where the second target light 90 is generated on the surface of the second electrode 30.

[0074] In this embodiment, by respectively arranging the first substance 70 in the first electrode 20 and the second substance 60 in the second electrode 30, under the irradiation of the first target light 80, the second target light 90 will be generated on the surface of the second electrode 30. By detecting the intensity and wavelength of the second target light 90, determine whether the first substance 70 and the second substance 60 are in contact. By determining whether the first substance 70 and the second substance 60 are in contact, determine whether the first electrode 20 and the second electrode 30 are short - circuited. By determining whether the first electrode 20 and the second electrode 30 are short - circuited, determine whether the first insulating layer 50 is working properly. When the first insulating layer 50 is abnormal, determine the abnormal position of the first insulating layer 50 according to the position of the second target light 90, thereby realizing the detection of the insulation performance of the first insulating layer 50 of the screen - printed electrode in a large range.

[0075] In some of these embodiments, the brightness of the second target light 90 is obtained according to the contrast between the second target light 90 and the background area; the contrast between the second target light 90 and the background area is collected by a microscope.

[0076] In some of these embodiments, the target number of layers of the first insulating layer 50 is determined; the intensity of the second target light 90 when the first insulating layer 50 is at the target number of layers is obtained; and a threshold is determined according to the intensity of the second target light 90.

[0077] Specifically, the target number of layers is the number of layers of the first insulating layer 50 when the first electrode 20 and the second electrode 30 change from being conductive to being insulating during the layer-by-layer printing of the first insulating layer 50. During the screen printing electrode printing process, the printing effect of the first insulating layer 50 can be monitored in real time. By quantitatively analyzing the second target light 90, the effect of the first insulating layer 50 can be viewed in real time, the target number of layers can be determined, and the thickness of the first insulating layer 50 can be monitored in real time, so as to achieve the best insulating effect with the least amount of the first insulating layer 50.
