Description

Technical Field

[0001] The present invention relates to a detection device, and more particularly to a detection device in which a first electrode and a second electrode are respectively disposed in a first cavity and a second cavity. Background Technology

[0002] Traditionally, in solution detection devices, the working electrode and reference electrode are placed in the same environment, with detection achieved by the test solution forming a circuit between them. However, this design does not suit the appropriate operating environments for each electrode. For example, the working electrode requires the test solution to be drained periodically, while the reference electrode needs to be immersed in a liquid environment to provide a stable reference voltage. Therefore, this can easily lead to decreased detection accuracy or shortened electrode lifespan. Furthermore, when a single electrode fails, the entire detection device becomes unusable, increasing maintenance costs.

[0003] Therefore, there is an urgent need to develop a detection device to improve the above-mentioned defects. Summary of the Invention

[0004] The present invention provides a detection device, characterized in that it comprises: a substrate assembly; a cover assembly disposed on the substrate assembly, wherein the substrate assembly and the cover assembly together form a first cavity and a second cavity; a first electrode disposed in the first cavity; a second electrode disposed in the second cavity; a connecting pipe connecting the first cavity and the second cavity; an inflow pipe connecting the first cavity or the second cavity; and an outflow pipe connecting the first cavity or the second cavity.

[0066] The following provides a detailed description of the electronic panel and printing apparatus according to embodiments of the present invention. It should be understood that the following description provides many different embodiments for different implementations of some embodiments of the present invention. The specific components and arrangements described below are merely for simple and clear description of some embodiments of the present invention. Of course, these are for illustrative purposes only and not for limiting the present invention. Furthermore, similar and / or corresponding reference numerals may be used in different embodiments to identify similar and / or corresponding components for clear description of the present invention. However, the use of these similar and / or corresponding reference numerals is only for simple and clear description of some embodiments of the present invention and does not imply any correlation between the different embodiments and / or structures discussed.

[0067] The embodiments of this invention can be understood in conjunction with the accompanying drawings, which are also considered part of the description of the invention. It should be understood that the drawings are not drawn to scale; in fact, the dimensions of components may be arbitrarily enlarged or reduced to clearly show the features of this disclosure. Furthermore, directional terms mentioned in this disclosure, such as up, down, front, back, left, and right, are only for reference to the directions in the drawings. Therefore, the directional terms used are for illustration and not for limiting the invention. In the drawings, the various figures illustrate general features of the methods, structures, and / or materials used in specific embodiments. However, these figures should not be construed as defining or limiting the scope or nature covered by these embodiments. For example, for clarity, the relative dimensions, thicknesses, and positions of various film layers, regions, and / or structures may be reduced or enlarged.

[0068] In this invention, a structure (or layer, component, substrate) located on / above another structure (or layer, component, substrate) can refer to two structures being adjacent and directly connected, or to two structures being adjacent but not directly connected. Indirect connection means that there is at least one intermediate structure (or intermediate layer, intermediate component, intermediate substrate, intermediate spacer) between the two structures, with the lower surface of one structure adjacent to or directly connected to the upper surface of the intermediate structure, and the upper surface of the other structure adjacent to or directly connected to the lower surface of the intermediate structure. The intermediate structure can be composed of a single or multiple solid or non-solid structure, without limitation. In this invention, when a structure is disposed "on" another structure, it may mean that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure, i.e., at least one structure is sandwiched between the structure and the other structure. In this invention, "relatively disposed" or "relative to… disposed" means that the components substantially overlap each other, but this invention is not limited thereto.

[0069] Furthermore, it should be understood that the ordinal numbers used in the specification and claims, such as "first," "second," etc., to modify components, do not in themselves imply or represent any prior ordinal number of that component (or those components), nor do they represent the order of one component with another, or the order of manufacturing processes. The use of these ordinal numbers is solely to clearly distinguish one component with a certain name from another component with the same name. The claims and specification may not use the same terminology; for example, "first component" in the specification may be "second component" in the claims.

[0070] In some embodiments of the present invention, terms such as joining and connecting, or interconnecting, unless specifically defined, may refer to two structures in direct contact, or to two structures not in direct contact, wherein another structure is disposed between the two structures. Furthermore, the terms joining and connecting may also include cases where both structures are movable or both structures are fixed. In addition, the terms "electrical connection" or "coupling" include any direct and indirect electrical connection means.

[0071] In this text, the terms "approximately," "substantially," and "roughly" typically indicate that a given value or range is within 10%, 5%, 3%, 2%, 1%, or 0.5%. Unless otherwise stated, the phrase "range between the first value and the second value" means that the range includes the first value, the second value, and other values ​​in between. Furthermore, any two values ​​or directions used for comparison may have a certain degree of error. If the first value is equal to the second value, it implies that there may be an error of approximately 10% between the first and second values; if the first direction is perpendicular to the second direction, the angle between the first and second directions may be between 80 and 100 degrees; if the first direction is parallel to the second direction, the angle between the first and second directions may be between 0 and 10 degrees. In this invention, the terms "given range is between the first value and the second value" and "given range falls within the range between the first value and the second value" indicate that the given range includes the first value, the second value, and other values ​​in between.

[0072] Furthermore, according to embodiments of the present invention, the thickness, length, width, height, or distance and angle between components can be measured using an optical microscope (OM), a scanning electron microscope (SEM), an alpha-step thickness gauge, an ellipsometry, or other suitable methods. Specifically, according to some embodiments, a scanning electron microscope can be used to obtain cross-sectional images of the structure and to measure the thickness, length, width, height, or distance and angle between components.

[0073] Throughout this specification and claims, certain terms are used to refer to specific components. Those skilled in the art will understand that electronic device manufacturers may use different names to refer to the same components. This document is not intended to distinguish between components that have the same function but different names. In the following specification and claims, words such as "comprising," "including," and "having" are open-ended terms and should therefore be interpreted as "including but not limited to...". Therefore, when the terms "comprising," "including," and / or "having" are used in the description of this disclosure, they specify the presence of the corresponding feature, area, step, operation, and / or component, but do not exclude the presence of one or more of the corresponding feature, area, step, operation, and / or component.

[0074] It should be understood that the following embodiments can be modified by substituting, recombining, or combining features from several different embodiments to complete other embodiments without departing from the scope of the invention. Features from different embodiments can be arbitrarily combined and used as long as they do not violate or conflict with the invention.

[0075] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It is understood that these terms, for example, as defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the background or context of this invention, and should not be interpreted in an idealized or overly formal manner, unless specifically defined in the embodiments of this invention.

[0076] It should be understood that the features described below can be replaced, recombined, or mixed in several different embodiments to complete other embodiments without departing from the scope of the present invention. Features between embodiments can be arbitrarily mixed and combined as long as they do not violate or conflict with the invention. It should be noted that the technical solutions provided in the different embodiments below can be substituted, combined, or mixed with each other to constitute another embodiment without violating the present invention.

Figure 1B for Figure 1A A cross-sectional diagram of line segment A-A'. Figure 1C and Figure 1D These are enlarged schematic diagrams of parts of the detection device. For ease of explanation, Figure 1A The cover assembly 2 has been omitted.

[0078] In embodiments of the present invention, such as Figure 1A and Figure 1B As shown, the detection device may include: a substrate assembly 1; a cover assembly 2 disposed on the substrate assembly 1, wherein the substrate assembly 1 and the cover assembly 2 together form a first cavity C1 and a second cavity C2; a first electrode E1 disposed in the first cavity C1; a second electrode E2 disposed in the second cavity C2; a connecting pipe 3 connecting the first cavity C1 and the second cavity C2; an inflow pipe 4 connecting the first cavity C1 or the second cavity C2; and an outflow pipe 5 connecting the first cavity C1 or the second cavity C2. The inflow pipe 4 can be connected to the first cavity C1, and the outflow pipe 5 can be connected to the second cavity C2. Thus, the solution can flow from the inflow pipe 4 into the first cavity C1, flow through the connecting pipe 3 to the second cavity C2, and finally flow out through the outflow pipe 5. Solution detection can be performed by forming a circuit between the first electrode E1 and the second electrode E2.

[0079] In embodiments of the present invention, such as Figure 1B As shown in the cross-sectional view, in the normal direction Z (Y direction) of the vertical substrate assembly 1, the first cavity C1 has a first width W1, and the connecting pipe 3 has a second width W2, wherein the first width W1 is greater than the second width W2. In an embodiment of the present invention, as... Figure 1BAs shown in the cross-sectional view, in the normal direction Z (Y direction) of the vertical substrate assembly 1, the second cavity C2 has a third width W3, and the third width W3 is greater than the second width W2. In this embodiment of the invention, the width of the first cavity C1 / second cavity C2 / connecting pipe 3 refers to the minimum width of the first cavity C1 / second cavity C2 / connecting pipe 3 in the direction perpendicular to the solution flow direction FD.

[0080] In embodiments of the present invention, such as Figure 1B and Figure 1C As shown, in the normal direction Z of the vertical substrate assembly 1, the first cavity C1 has a first cross-sectional area A1, and the connecting pipe 3 has a second cross-sectional area A2, wherein the first cross-sectional area A1 is larger than the second cross-sectional area A2.

Figure 1B and Figure 1D As shown, in the normal direction Z of the vertical substrate assembly 1, the second cavity C2 has a third cross-sectional area A3, and the third cross-sectional area A3 is larger than the second cross-sectional area A2. In this embodiment of the invention, the cross-sectional area of ​​the first cavity C1 / second cavity C2 / connecting pipe 3 refers to the minimum cross-sectional area of ​​the first cavity C1 / second cavity C2 / connecting pipe 3 in the direction perpendicular to the solution flow direction FD.

[0081] In this invention, the material of substrate assembly 1 may include quartz, glass, silicon wafer, sapphire, polycarbonate (PC), polyimide (PI), polypropylene (PP), polyethylene terephthalate (PET), other plastics or polymers, other inorganic materials, or other organic materials, or combinations thereof, but this invention is not limited thereto. In this invention, the material of cover assembly 2 may include quartz, glass, polycarbonate (PC), polyimide (PI), polypropylene (PP), polyethylene terephthalate (PET), other plastics or polymers, other inorganic materials, or other organic materials, or combinations thereof, but this invention is not limited thereto.

[0082] In this invention, the dimensions of the first cavity C1 and the second cavity C2 are not particularly limited. For example, in a top view, the projected area of ​​the first cavity C1 on the substrate assembly 1 can be greater than, equal to, or less than the projected area of ​​the second cavity C2 on the substrate assembly 1. In embodiments of this invention, such as Figure 1AAs shown, in the top view, the projected area of ​​the first cavity C1 on the substrate assembly 1 may be smaller than the projected area of ​​the second cavity C2 on the substrate assembly 1, but the present invention is not limited thereto. In the present invention, the shapes of the first cavity C1 and the second cavity C2 are not particularly limited. For example, in the top view, the first cavity C1 and the second cavity C2 may each be circular, elliptical, rectangular, prismatic, hexagonal, octagonal, or other irregular shapes, but the present invention is not limited thereto. In the embodiments of the present invention, in the top view, as... Figure 1A As shown, the first cavity C1 can be hexagonal, and the second cavity C2 can be circular.

[0083] In this invention, the dimensions of the first electrode E1 and the second electrode E2 are not particularly limited. For example, in a top view, the projected area of ​​the first electrode E1 on the substrate assembly 1 can be greater than, equal to, or less than the projected area of ​​the second electrode E2 on the substrate assembly 1. In embodiments of this invention, such as Figure 1A As shown, in the top view, the projected area of ​​the first electrode E1 on the substrate assembly 1 can be larger than the projected area of ​​the second electrode E2 on the substrate assembly 1, but the present invention is not limited thereto. In the present invention, the shapes of the first electrode E1 and the second electrode E2 are not particularly limited. For example, in the top view, the first electrode E1 and the second electrode E2 can each be circular, elliptical, rectangular, prismatic, hexagonal, octagonal, or other irregular shapes, but the present invention is not limited thereto. In the embodiments of the present invention, in the top view, as... Figure 1A As shown, the first electrode E1 and the second electrode E2 can be circular.

[0084] In this embodiment of the invention, the first electrode E1 can be a working electrode, and the second electrode E2 can be a reference electrode. However, the invention is not limited thereto. In other embodiments, the first electrode E1 can be a reference electrode, and the second electrode E2 can be a working electrode. The working electrode can comprise a metallic material and a sensing material. Suitable metallic materials can include gold, silver, copper, aluminum, titanium, chromium, nickel, molybdenum, or combinations thereof, but the invention is not limited thereto. Suitable sensing materials can be metal oxides, such as indium tin oxide (ITO), zinc dioxide, tin dioxide, indium zinc oxide (IZO), indium tin zinc oxide (ITZO), indium gallium zinc oxide (IGZO), aluminum zinc oxide (AZO), ruthenium oxide (RuO2; RuO4), or combinations thereof, but the invention is not limited thereto. The reference electrode can comprise silver chloride. In this embodiment of the invention, the detection device can be an acid-base value detection device, used to detect the acid-base value (pH value) of the solution to be tested. When the working electrode is affected by the pH value of different test solutions, i.e., when the solutions have different hydrogen ion concentrations, the working electrode can exhibit different induced voltage changes to detect the pH value of different test solutions. In embodiments of the present invention, the surface of the working electrode can be modified in various ways as needed to enable its application in other detection methods. For example, the surface of the working electrode can be modified with gold nanoparticles, thus allowing it to function as a glucose sensing electrode, enabling the detection device to be used for glucose detection. In another embodiment of the present invention, although not shown in the figure, multiple working electrodes can be disposed within the first cavity C1 to simultaneously detect different properties of the test solutions, thereby saving detection time and improving detection efficiency.

[0085] In this invention, the connecting pipe 3, the inflow pipe 4, and the outflow pipe 5 are channels through which the solution can pass. The materials of the connecting pipe 3, the inflow pipe 4, and the outflow pipe 5 may each include quartz, glass, polycarbonate (PC), polyimide (PI), polypropylene (PP), polyethylene terephthalate (PET), resin, rubber, other plastics or polymers, other inorganic materials or other organic materials, or combinations thereof, but this invention is not limited thereto.

[0086] Figure 2A This is a top view schematic diagram of some detection devices according to an embodiment of the present invention. Figure 2B for Figure 2AA cross-sectional view of line segment B-B'. Wherein, Figure 2A The detection device and Figure 1A Similar, except for the following differences. Furthermore, for ease of explanation, Figure 2A The cover assembly 2 has been omitted.

[0087] In embodiments of the present invention, such as Figure 2A and Figure 2B As shown, substrate assembly 1 may include a first sub-substrate 11 and a second sub-substrate 12, with a distance D1 between them. The first sub-substrate 11 and the cover assembly 2 together form a first cavity C1, and the second sub-substrate 12 and the cover assembly 2 together form a second cavity C2. An inflow pipe 4 can be connected to the first cavity C1, and an outflow pipe 5 can be connected to the second cavity C2. Thus, the solution can flow into the first cavity C1 from the inflow pipe 4, flow to the second cavity C2 via the connecting pipe 3, and finally flow out through the outflow pipe 5. With this design, the first electrode E1 and the second electrode E2 can be disposed on different sub-substrates; that is, the first electrode E1 is disposed on the first sub-substrate 11, and the second electrode E2 is disposed on the second sub-substrate 12. Therefore, when either the first electrode E1 or the second electrode E2 is damaged, either the first sub-substrate 11 or the second sub-substrate 12 can be replaced individually, thereby reducing maintenance costs.

[0088] In this invention, Figure 2A and Figure 2B Other detailed features of the detection device can be seen as follows Figure 1A and Figure 1B As shown, it will not be elaborated further here.

[0089] Figure 2C This is a top view schematic diagram of part of the detection device according to an embodiment of the present invention. Figure 2C The detection device and Figure 2B Similar, except for the following differences.

[0090] In another embodiment of the invention, due to Figure 2C The detection device and Figure 2B Similar, therefore, Figure 2C A top-view schematic diagram of the detection device can be referenced. Figure 2A As shown, Figure 2A and Figure 2C As shown, the cover assembly 2 may include a first part 21 and a second part 22, which are spaced apart by a distance D2. The first part 21 and the substrate assembly 1 together form a first cavity C1, and the second part 22 and the substrate assembly 1 together form a second cavity C2. More specifically, as... Figure 2CAs shown, the first part 21 of the cover assembly 2 and the first sub-substrate 11 together form the first cavity C1, and the second part 22 of the cover assembly 2 and the second sub-substrate 12 together form the second cavity C2.

[0091] In this invention, the first portion 21, the first sub-substrate 11, and the first electrode E1 of the cover assembly 2 can form a first unit U1, and the second portion 22, the second sub-substrate 12, and the second electrode E2 of the cover assembly 2 can form a second unit U2. With this design, when either the first electrode E1 or the second electrode E2 is damaged, either the first unit U1 or the second unit U2 can be replaced individually, thereby reducing maintenance costs.

[0092] In this invention, Figure 2C Other detailed features of the detection device can be seen as follows Figure 2A and Figure 2B As shown, it will not be elaborated further here.

[0093] Figure 3A This is a top view schematic diagram of part of the detection device according to an embodiment of the present invention. Figure 3A The detection device and Figure 2A Similar, except for the following differences. Furthermore, for ease of explanation, Figure 3A The cover assembly 2 has been omitted.

[0094] In embodiments of the present invention, such as Figure 3A As shown, the inflow pipe 4 is connected to the first cavity C1, and the outflow pipe 5 is also connected to the first cavity C1. Thus, by controlling the dimensions of the pipes (including the connecting pipe 3, the inflow pipe 4, and the outflow pipe 5) and / or by applying external force (e.g., pressurized mercury), the solution can flow from the inflow pipe 4 into the first cavity C1 and outflow from the outflow pipe 5. The solution can also form a circuit between the first electrode E1 and the second electrode E2 through the connecting pipe 3 for solution detection.

[0095] In this embodiment of the invention, a standard solution can be pre-filled into the second chamber C2, immersing the second electrode E2 in the standard solution to provide a stable reference voltage. During solution detection, the solution to be tested flows into the first chamber C1 through the inflow pipe 4. The solution to be tested forms a circuit between the first electrode E1 and the second electrode E2 through the connecting pipe 3, allowing the first electrode E1 to detect the solution to be tested based on changes in the induced voltage. In this way, the first electrode E1 (e.g., a working electrode) and the second electrode E2 (e.g., a reference electrode) can each be maintained in a suitable operating environment, thereby improving the accuracy of detection or extending the service life of the electrodes.

[0096] In this invention, Figure 3A The cover assembly 2 can be referenced. Figure 2B and Figure 2C As shown, therefore, Figure 3AOther detailed features of the detection device can be seen as follows Figures 2A to 2C The details mentioned above will not be repeated here.

[0097] Figure 3B This is a top view schematic diagram of part of the detection device according to an embodiment of the present invention. Figure 3B The detection device and Figure 2A and Figure 3A Similar, except for the following differences. Furthermore, for ease of explanation, Figure 3B The cover assembly 2 has been omitted.

[0098] In embodiments of the present invention, such as Figure 3B As shown, substrate assembly 1 may further include a third sub-substrate 13, wherein the second sub-substrate 12 is disposed between the first sub-substrate 11 and the third sub-substrate 13. The third sub-substrate 13 may be combined with cover assembly 2 (such as...) Figure 2B (As shown) together form the third cavity C3. In addition, the detection device may also include: a third electrode E3 disposed in the third cavity C3; another connecting pipe 3' connecting the third cavity C3 and the second cavity C2; another inflow pipe 4' connecting the third cavity C3; and another outflow pipe 5' connecting the third cavity C3.

[0099] The solution to be tested can flow into the first cavity C1 from the inlet pipe 4 and out from the outlet pipe 5. This solution can form a circuit between the first electrode E1 and the second electrode E2 through the connecting pipe 3 for detection. Another solution to be tested can flow into the third cavity C3 from another inlet pipe 4' and out from another outlet pipe 5'. This solution can form a circuit between the third electrode E3 and the second electrode E2 through another connecting pipe 3' for detection. Thus, the first electrode E1 and the third electrode E3 can share the reference voltage provided by the second electrode E2, allowing simultaneous detection of different solutions and improving detection efficiency. Since the first electrode E1, the second electrode E2, and the third electrode E3 are disposed on different sub-substrates, when one or more of the first electrode E1, the second electrode E2, and the third electrode E3 are damaged, the first sub-substrate 11, the second sub-substrate 12, and / or the third sub-substrate 13 containing the damaged electrode can be replaced individually, thereby reducing maintenance costs.

[0100] In this invention, the other connecting pipe 3', the other inflow pipe 4', and the other outflow pipe 5' are channels that allow the solution to pass through, and the materials of the other connecting pipe 3', the other inflow pipe 4', and the other outflow pipe 5' can each be as described in the connecting pipe 3, the inflow pipe 4, and the outflow pipe 5, respectively, and will not be repeated here. In this invention, Figure 3B The cover assembly 2 can be referenced. Figure 2B As shown, this will not be repeated here. Furthermore, Figure 3B The cover assembly 2 can also be like Figure 2C The diagram shows a first part 21, a second part 22, and a third part (not shown), wherein the third part (not shown) can form a third cavity C3 together with the third sub-substrate 13. Since the first cavity C1, the second cavity C2, and the third cavity C3 are formed by different parts of different sub-substrate and cover assembly 2, when one or more of the first electrode E1, the second electrode E2, and the third electrode E3 are damaged, the first sub-substrate 11, the second sub-substrate 12, and / or the third sub-substrate 13 containing the damaged electrode, as well as the corresponding first part 21, the second part 22, and / or the third part (not shown) of the cover assembly 2 can be replaced individually, thereby reducing maintenance costs.

Furthermore, for ease of explanation, Figure 4A The cover assembly 2 is omitted in the text.

[0103] In embodiments of the present invention, such as Figure 4A and Figure 4B As shown, the detection device may also include another cover 6, which is disposed on the cover assembly 2, wherein the cover assembly 2 and the other cover 6 together form a connecting pipe 3. The solution can flow into the first cavity C1 from the inflow pipe 4, and flow to the second cavity C2 through the connecting pipe 3 formed by the cover assembly 2 and the other cover 6, and finally flow out through the outflow pipe 5.

[0104] In embodiments of the present invention, such as Figure 4B As shown, the cover assembly 2 can form a first cavity C1 with the first sub-substrate 11, and the cover assembly 2 can form a second cavity C2 with the second sub-substrate 12. Through the above design, the first electrode E1 and the second electrode E2 can be disposed on different sub-substrates, i.e., the first electrode E1 is disposed on the first sub-substrate 11, and the second electrode E2 is disposed on the second sub-substrate 12. Thus, when either the first electrode E1 or the second electrode E2 is damaged, either the first sub-substrate 11 or the second sub-substrate 12 can be replaced individually, thereby reducing maintenance costs.

These pumps can supply different test solutions (e.g., test solutions P, Q, and R) to the inflow pipe 4 for detection of different solutions. More specifically, during the detection process, liquid pump 81 can supply test solution P to the inflow pipe 4 for detection. After detection, air pump 7 can dry the remaining test solution P in the inflow pipe 4. Then, liquid pump 82 can supply test solution Q to the inflow pipe 4.
