技术领域technical field
本公开案涉及导电弹性体在电子器件中的使用。具体而言，本公开案涉及传感器中使用的电极。更具体而言，本公开案涉及检测包括但不限于尿液、汗液、血液、粪便、唾液和脊髓液中所存在电解质的传感器中使用的电极。The present disclosure relates to the use of conductive elastomers in electronic devices. In particular, the disclosure relates to electrodes used in sensors. More specifically, the present disclosure relates to electrodes used in sensors that detect electrolytes present in, but not limited to, urine, sweat, blood, feces, saliva, and spinal fluid.
背景技术Background technique
现有流体检测报警器通过一个安全别针、磁铁或专用夹子而附着在用户衣服上。事实上这些方法不仅具有局限性，而且也给用户造成了各种不便。尽管在用户的衣服上附着一个流体检测报警器能确保在充分靠近时听到报警，但是如果用户身上覆盖有毛毯或一些其它覆盖物，则报警的声音很容易变得低沉。此外，为确保他/她不睡在流体检测报警器上，用户将不得不睡在一个位置。再者，安全别针和专用夹子可能很容易影响用户的舒适和便利，而磁体往往没有足以吸住流体检测报警器的强大吸力。Existing fluid detection alarms attach to the user's clothing with a safety pin, magnet, or special clip. In fact, these methods not only have limitations, but also cause various inconveniences to users. While attaching a fluid detection alarm to the user's clothing ensures that the alarm can be heard when sufficiently close, the sound of the alarm can easily become muffled if the user is covered in a blanket or some other covering. Additionally, the user will have to sleep in one position to ensure that he/she does not fall asleep on the fluid detection alarm. Furthermore, safety pins and specialized clips can easily interfere with user comfort and convenience, and magnets are often not strong enough to hold fluid detection alarms.
本部分所描述的方法可以实施，但不一定是先前已构思的方法。因此，除非本文另有说明，本部分所描述的方法不是本申请的权利要求的现有技术，并且不被承认为本节所包含的现有技术。The approaches described in this section can be implemented, but are not necessarily approaches that have been previously conceived. Therefore, unless otherwise indicated herein, the approaches described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
众所周知，导电聚合物和导电弹性体具有弹性和导电性，因此以垫片或密封件的形式使用。作为导体的包括一些有用性能，包括方便的成型、耐腐蚀性和密封接触界面。但是，由于很难得到金属一样低的电阻率，其作为导体的使用会有限。导电弹性体一般由引入导电碳素或金属颗粒的硅橡胶构成。材料的电阻率随导电粒子的含量而变化。Conductive polymers and conductive elastomers are known to be elastic and conductive and thus used in the form of gaskets or seals. Some useful properties as conductors include easy molding, corrosion resistance, and hermetic contact interfaces. However, its use as a conductor is limited due to the difficulty of obtaining a resistivity as low as metals. Conductive elastomers generally consist of silicone rubber incorporating conductive carbon or metal particles. The resistivity of the material varies with the content of conductive particles.
与报警装置通过电路连接的传感器电极用于治疗遗尿症是众所周知的事情。尿液中存在的电解质通过填充电极之间的间隙或通道实现报警电路闭合，由此指示出现排尿的情况。大多数现有电极有一组平行的正负极图形，否则就是线性蛇形的图形，故此尿液必须接触裸线使报警电路闭合。裸线通过绝缘体中的间隙能够与尿液接触，这样尿液就必须进入正负极间隙以接触电线并使电路闭合。The use of sensor electrodes in circuit connection with alarm devices for the treatment of enuresis is well known. Electrolytes present in the urine close the alarm circuit by filling the gap or channel between the electrodes, thereby indicating the occurrence of urination. Most of the existing electrodes have a group of parallel positive and negative pole patterns, otherwise it is a linear serpentine pattern, so the urine must contact the bare wire to close the alarm circuit. The bare wire is able to come into contact with the urine through the gap in the insulator, so the urine must enter the positive and negative gap to contact the wire and close the circuit.
现有电解质传感器仅限于沿两个导电塑料半区之间的狭窄间隙闭合，每个半区分别与从接线座伸入传感器主体的一个正极导电元件和负极导电元件接触。因为电解质可能存在于一个塑料半区而不使电路闭合，且整个传感器表面仅由两个半区组成，所以这种情况存在不利之处。本公开案不限于这种方式，通过本发明的导电弹性体的正负轨迹电极连接到各自电线端子引线端，并且导电弹性体轨迹电极在整个传感器“轨迹图案”上都相互靠近，从而使电解质可以通过同时接触沿占去整个传感器表面的轨迹图案的正负轨迹电极表面上任何点就会使电路闭合。这是一个很重要的改进，这是因为要考虑到阴茎或其它电解质源在电解质位置方面不可预测，故此在神经系统训练中每一刻都要争取时，每个闭合电路所需的电解质体积或数量应尽可能低，对应的电路闭合应尽可能迅速，以实现有效的治疗。传感器轨迹图案的实例如图2A-2K中所示。Existing electrolyte sensors are limited to closure along a narrow gap between two conductive plastic halves, each in contact with a positive and negative conductive element that protrudes from the terminal block into the sensor body. This situation is disadvantageous because the electrolyte may be present in one plastic half without closing the circuit, and the entire sensor surface consists of only two halves. The present disclosure is not limited in this way, by connecting the positive and negative trace electrodes of the conductive elastomer of the present invention to the respective wire terminal lead ends, and the conductive elastomer trace electrodes are close to each other throughout the sensor "trace pattern", so that the electrolyte The circuit can be closed by simultaneous contact at any point on the surface of the positive and negative track electrodes along a track pattern occupying the entire sensor surface. This is an important improvement due to the unpredictability of the location of the electrolytes in the penis or other electrolyte sources, so the volume or amount of electrolytes required for each closed circuit is a struggle at every moment during neurological training should be as low as possible and the corresponding circuit closure should be as rapid as possible to achieve effective therapy. Examples of sensor track patterns are shown in Figures 2A-2K.
与现有解决方案相比的另一个优势是使用热成型安装轨迹电极。所述热成型弹性体电极显著比现有传感器薄膜或印刷电路更大更牢固，能够耐受用户穿戴过夜，也能耐受尿液等腐蚀性物质的降解。使用固体非柔性载体上专用印刷电路板检测导液管部位的“湿度传感器”。这种电路不能耐受尿液的腐蚀性效应与佩戴者的过夜连续使用的合并作用。Another advantage over existing solutions is the use of thermoforming to mount the track electrodes. The thermoformed elastomeric electrodes are significantly larger and stronger than existing sensor films or printed circuits, are able to withstand overnight wear by the user, and are also resistant to degradation by corrosive substances such as urine. A "wetness sensor" at the catheter site is detected using a dedicated printed circuit board on a solid non-flexible carrier. Such circuits are not resistant to the corrosive effects of urine combined with overnight continuous use by the wearer.
用来检测尿液以外物质中存在的电解质所用的传感器将以传感器电极之间形成桥接的原理运行，由此执行闭合电路的功能，为不同治疗形式提供帮助，具体取决于传感器检测的内容、上游电子器件以及处理的人体系统。其它目的的实例包括检测导液管部位的血液和脊髓液泄漏和感知尿布中的粪便。这些实例并不排除其它用途，而是要描述一些在传感器电极中使用的导电弹性体的一些应用，以及在哪些方面显示出导电弹性体电极在现有解决方案上做了普遍的改进，特别是因为电解质可以接触可靠性导电弹性体轨迹电极因为很多原因(但特别是因为电解质可使电解质与散布的金属线触点接触或需要足够的体积和方向性连接塑料电极半区)比现有解决方案普遍有改善。Sensors used to detect electrolytes present in substances other than urine will operate on the principle of forming a bridge between the electrodes of the sensor, thereby performing the function of a closed circuit, aiding different treatment modalities, depending on what the sensor detects, the upstream Electronic devices and human body systems for processing. Examples of other purposes include detecting blood and spinal fluid leaks at catheter sites and sensing feces in diapers. These examples are not to exclude other uses, but to describe some applications of conductive elastomers used in sensor electrodes, and in which respects conductive elastomer electrodes generally improve on existing solutions, especially Because the electrolyte can contact the reliability of the conductive elastomer trace electrodes for many reasons (but especially because the electrolyte can make contact with interspersed metal wire contacts or require sufficient volume and directionality to connect the plastic electrode halves) than existing solutions Generally improved.

具体实施方式Detailed ways
在下列描述中，出于说明的目的，陈述了大量具体细节，以便提供对实施例的充分了解。但是，本领域的技术人员会应该理解，本本发明的技术方案也可在没有这些具体细节的情况下实施。In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. However, those skilled in the art should understand that the technical solutions of the present invention can also be implemented without these specific details.
本公开案涉及可用于检测汗液、血液、尿液、粪便、唾液、脊髓液的电解质传感器，所有这些都含有能够在电极间传导电流的电解质。通常，本公开案还用来测量任何可能分析物的电极间隙之间的电阻。The present disclosure relates to electrolyte sensors that can be used to detect sweat, blood, urine, feces, saliva, spinal fluid, all of which contain electrolytes capable of conducting electrical current between electrodes. In general, the present disclosure is also used to measure the resistance between the electrode gaps for any possible analytes.
本公开案中所述的优点可能源自电解质传感器由导电弹性体制成以及具有各种性能，这些性能能够实现传感器形状和面积设计(例如涉及阴茎、尿液或电解质来源位置的多变性)方面的灵活性、用电极面积和反应时间函数表示的电解质导电的更高灵敏性、传感器耐腐蚀性、传感器对汗液、血液、尿液、粪便或脊髓液的导电一致性、传感器柔性和舒适性以及由于热成型结构所带来的传感器耐久性。The advantages described in this disclosure may result from the fact that the electrolyte sensor is made of a conductive elastomer and possesses various properties that enable flexibility in sensor shape and area design (e.g. involving variability in the location of the penis, urine, or source of electrolytes). Flexibility, higher sensitivity of electrolyte conduction as a function of electrode area and reaction time, sensor corrosion resistance, sensor conduction consistency to sweat, blood, urine, feces or spinal fluid, sensor flexibility and comfort, and due to Sensor durability due to thermoformed construction.
本公开案中使用导电弹性体的电解质传感器可以用于检测电解质(包括但不限于那些存在于尿液、汗液、唾液、粪便、脊髓液、血液中的电解质)，还可以作为任何电解质的传感器运行。Electrolyte sensors using conductive elastomers in this disclosure can be used to detect electrolytes (including but not limited to those present in urine, sweat, saliva, feces, spinal fluid, blood) and can also function as sensors for any electrolyte .
但应理解“电解质”包括但不限于下列物质中存在的电解质：汗液、血液、尿液、粪便、唾液、或脊髓液。使用导电弹性体的电解质传感器的一个应用实例是在遗尿症治疗领域，由此将电解质传感器接入由传感器中尿液的存在触发的报警电路。传感器包含正负导电弹性体轨迹电极、一个或多个柔性非导电有机硅基底以及用于隔开电极的一个或多个间隙或通道。“正”、“负”轨迹电极被定义为相应连接到终端并与正负电池端子相连的正负接线端引线电极。导电弹性体轨迹电极优选热成型高柔性的非导电性有机硅基底，间隙或通道借此将整个图案上的正负轨迹电极分隔开。在一些实施例中，柔性非导电有机硅基底可以使正负轨迹电极分离，并且有足够的刚性以在正负轨迹电极之间提供一个距离。It is understood, however, that "electrolytes" include, but are not limited to, those present in sweat, blood, urine, feces, saliva, or spinal fluid. An example of an application of an electrolyte sensor using a conductive elastomer is in the field of enuresis treatment, whereby the electrolyte sensor is connected to an alarm circuit triggered by the presence of urine in the sensor. The sensor consists of positive and negative conductive elastomer trace electrodes, one or more flexible non-conductive silicone substrates, and one or more gaps or channels separating the electrodes. "Positive" and "negative" trace electrodes are defined as the positive and negative terminal lead electrodes respectively connected to the terminals and connected to the positive and negative battery terminals. The conductive elastomer trace electrodes are preferably thermoformed highly flexible non-conductive silicone substrates, whereby gaps or channels separate the positive and negative trace electrodes across the pattern. In some embodiments, the flexible non-conductive silicone substrate can separate the positive and negative trace electrodes and is sufficiently rigid to provide a distance between the positive and negative trace electrodes.
所述轨迹电极可设置在柔性非导电有机硅基底的顶部，也可陷入柔性非导电有机硅基底。间隙或通道可能包含使用可用的空气作为气体绝缘体的空间空穴，或者包含通过由基底中有机硅等实体绝缘材料组成的间隙或通道分隔开凹式电极。因此，柔性非导电有机硅基底可以将一个或多个正负轨迹电极分离。所述间隙或通道不限于均匀大小，由此整个轨迹图案的间隙或通道大小可能不均匀。电解质(如尿液中存在的电解质)，形成了跨相邻正负轨迹电极之间间隙或通道的桥接，造成电路闭合，尿液中存在的电解质由此能够在正负轨迹电极之间传导电荷。电路闭合后连接报警装置或向远程报警或其它电子装置发送信号的发射器。连接的电路可以闭合。在一些实施例中，使用导电弹性体的电解质传感器包括电解质传感器。The trace electrodes can be placed on top of the flexible non-conductive silicone substrate, or embedded in the flexible non-conductive silicone substrate. Gaps or channels may consist of steric voids using available air as a gas insulator, or contain recessed electrodes separated by gaps or channels composed of a solid insulating material such as silicone in the substrate. Thus, a flexible non-conductive silicone substrate can separate one or more positive and negative track electrodes. The gaps or channels are not limited to a uniform size, whereby the size of the gaps or channels may not be uniform across the track pattern. Electrolytes, such as those found in urine, that form a bridge across the gap or channel between adjacent positive and negative trace electrodes, resulting in a closed circuit, whereby electrolytes present in urine are able to conduct charge between the positive and negative trace electrodes . A transmitter that connects to an alarm device when a circuit is closed or sends a signal to a remote alarm or other electronic device. The connected circuit can be closed. In some embodiments, electrolyte sensors using conductive elastomers include electrolyte sensors.
在一些实施例中，使用导电弹性体的电解质传感器通过使用导电弹性体制成的电解质传感器电极而提高了电解质传感器检测存在的电解质信号的速度。导电弹性体也可在沿其整个表面的任何一点传导电流。因此，在正导电弹性体电极和负导电弹性体之间的电路可以闭合。正负电极可以使用金属导线、导电弹性体的其它部分或以任何方式被连接到电源。电流可以供给至电解质传感器部分的电极。In some embodiments, using a conductive elastomer electrolyte sensor increases the speed at which the electrolyte sensor detects the presence of electrolyte signals by using electrolyte sensor electrodes made of conductive elastomer. Conductive elastomers can also conduct electrical current at any point along their entire surface. Thus, an electrical circuit can be closed between the positive conductive elastomer electrode and the negative conductive elastomer. The positive and negative electrodes can be connected to the power source using metal wires, other parts of conductive elastomer, or in any manner. Electric current may be supplied to the electrodes of the electrolyte sensor portion.
在一些实施例中，金属导线可以通过导线压接头嵌入柔性非导电有机硅基底 (通过使用热硫化和热成型完成)而被连接到正负轨迹电极。In some embodiments, metallic wires may be connected to the positive and negative trace electrodes by wire crimping embedded into a flexible non-conductive silicone substrate (done by using heat vulcanization and thermoforming).
在一些实施例中，使用导电弹性体的电解质传感器通过使用导电弹性体制成的电解质传感器电极而提高了电解质的特异性，以对所需的电解质做出反应。在形成间隙两端的电流过程中，弹性体组成和轨迹电极之间的间隙或通道的大小是所需克服电阻数值的函数。In some embodiments, electrolyte sensors using conductive elastomers have increased electrolyte specificity by using electrolyte sensor electrodes made of conductive elastomers to respond to desired electrolytes. The composition of the elastomer and the size of the gap or channel between the trace electrodes are a function of the amount of resistance required to overcome the current flow across the gap.
在一些实施例中，使用导电弹性体的电解质传感器可通过使用导电弹性体制成尿传感器电极并将其通过轨迹图案连接到高柔性非导电有机硅基底来改进尿传感器的功能性形状，故此阴茎在夜间可改变定位，故此导电弹性体轨迹电极可设计成图案检测几乎任何形状有用面积的尿液。In some embodiments, the electrolyte sensor using a conductive elastomer can improve the functional shape of the urine sensor by using a conductive elastomer to make the urine sensor electrodes and connecting them to a highly flexible non-conductive silicone substrate through a trace pattern, so that the penis is in the Positioning can be changed overnight, so the conductive elastomer track electrodes can be designed to be patterned to detect urine in useful areas of almost any shape.
在一些实施例中，通过减少激活电解质传感器所需的电解质的量，并使用导电弹性体制成电解质传感器，使得使用导电弹性体的电解质传感器改进了电解质检测的最先进技术。In some embodiments, electrolyte sensors using conductive elastomers improve the state-of-the-art in electrolyte detection by reducing the amount of electrolyte required to activate the electrolyte sensor, and making the electrolyte sensor out of conductive elastomers.
在一些实施例中，通过使用导电弹性体制成电解质传感器，并使用柔性非导电有机硅基底或桥接部分，使得使用导电弹性体的电解质传感器改善了电解质传感器的柔性。In some embodiments, the electrolyte sensor using a conductive elastomer improves the flexibility of the electrolyte sensor by using a conductive elastomer to make the electrolyte sensor and using a flexible non-conductive silicone substrate or bridge portion.
在一些实施例中，通过使用导电弹性体制成电解质传感器，使用柔性有机硅制成基底，并借助弹性体的固有性质(包括相对温暖的触感，并且具有柔软圆形边缘和棱角)，使得使用导电弹性体的电解质传感器改善了用户所穿戴电解质传感器的舒适性。增加的舒适性是因为在电解质传感器中将金属替换成了弹性体，从而最大限度地减少了电解质传感器结构中坚硬、锋利材料的使用。In some embodiments, the electrolyte sensor is made of a conductive elastomer, the substrate is made of flexible silicone, and the inherent properties of elastomers, including relatively warm to the touch, and having soft rounded edges and corners, allow the use of conductive The elastomeric electrolyte sensor improves the comfort of the electrolyte sensor worn by the user. The increased comfort is due to replacing the metal with an elastomer in the electrolytic sensor, which minimizes the use of hard, sharp materials in the electrolytic sensor construction.
在一些实施例中，通过将热成型将电解质传感器电极和引线连接至柔性非导电有机硅基底，使得使用导电弹性体的电解质传感器提高了电解质传感器的耐久性。In some embodiments, the electrolyte sensor using a conductive elastomer improves the durability of the electrolyte sensor by thermoforming the electrolyte sensor electrodes and leads to a flexible non-conductive silicone substrate.
在一些实施例中，通过使用导电弹性体以替代金属导线制成电解质传感器，使得使用导电弹性体的电解质传感器提高了电解质传感器的耐腐蚀性。In some embodiments, the electrolyte sensor using a conductive elastomer improves the corrosion resistance of the electrolyte sensor by using a conductive elastomer instead of a metal wire to make the electrolyte sensor.
制备导电弹性体的化学方法众所周知，其主要使用导电性粒子构成混合弹性体。但应当理解的是，许多等效的化合物可用于创造能形成合适正负电极的弹性体化合物。此外，这些化合物可以归类为聚合物而非弹性体。本公开案的弹性体组成的优选实施例如下表所示。The chemical methods for preparing conductive elastomers are well known and mainly use conductive particles to form hybrid elastomers. It should be understood, however, that many equivalent compounds can be used to create elastomeric compounds that form suitable positive and negative electrodes. Furthermore, these compounds can be classified as polymers rather than elastomers. Preferred examples of elastomer compositions of the present disclosure are shown in the table below.
本具体实施方案表邠及以上发明内容中所描述实施例的特征和应用并非包括了所有的情况。基于以下附图、说明书和权利要求，本领域的普通技术人员会很清楚许多本发明的其它的特征和优点。The characteristics and applications of the embodiments described in the Table of Specific Embodiments and the Summary of the Invention above do not cover all situations. Many other features and advantages of the present invention will be apparent to one of ordinary skill in the art from the following drawings, description and claims.
图1为立体透视图，示出了进线端子50、70固定到基底110和轨迹电极150、 170。轨迹电极150、170可以被间隙或通道120进行物理或电气上的分离，随后可以对其填充电解质，从而可闭合电路。FIG. 1 is a perspective view showing the incoming terminals 50 , 70 secured to the base 110 and the track electrodes 150 , 170 . The trace electrodes 150, 170 may be physically or electrically separated by gaps or channels 120, which may then be filled with electrolyte to close the electrical circuit.
用于分离正、负轨迹电极150、170以保持轨迹电极之间所需距离的方法包括但不限于，在各电极之间所需距离上将轨迹电极150、170热成型于基底110 的热成型方法，或者在轨迹电极之间使用非导电“桥”的方法(其中，可以使用基底，也可以不使用基底)。示范性的实施例为：使用柔性非导电有机硅基底，通过热成型方法，将进线端子50、70可连接到轨迹电极150、170和基底110 上，以防止或不易使接线端子50、70在使用过程中移位。裸线的接线端子50、 70可以定位于靠近各电极的部分。有机硅基底110中的有机硅可以熔融于裸线的接线端子50、70周围，且连接点可以被硫化。使用热成型方法将接线端子安装在电极上具有额外的优势：可以使电解质传感器的制造摆脱与金属导线成型相关的物理和财务限制因素，以转入轨迹图案方式，这样对弹性体轨迹模具有利。Methods for separating the positive and negative trace electrodes 150, 170 to maintain the desired distance between the trace electrodes include, but are not limited to, thermoforming the trace electrodes 150, 170 to the substrate 110 at the desired distance between the electrodes. method, or using a non-conductive "bridge" between trace electrodes (where a substrate may or may not be used). An exemplary embodiment is: using a flexible non-conductive silicone substrate, the incoming terminals 50, 70 can be connected to the trace electrodes 150, 170 and the substrate 110 by a thermoforming method, so as to prevent or make it difficult to make the connecting terminals 50, 70 Shifts during use. Terminals 50, 70 for bare wires may be located near the respective electrodes. The silicone in the silicone substrate 110 can be fused around the bare wire terminals 50, 70, and the connection points can be vulcanized. Mounting the terminals on the electrodes using thermoforming has the added advantage of freeing the fabrication of electrolytic sensors from the physical and financial constraints associated with forming metallic wires to move to a track patterning approach, which favors elastomeric track dies.
热成型方法还是将接线端子50、70连接到有机硅基底110的优选手段。本公开案还预期使用铆钉、螺丝、摩擦和/或压缩连接手段。Thermoforming methods are also the preferred means of attaching the terminals 50 , 70 to the silicone substrate 110 . The present disclosure also contemplates the use of rivets, screws, friction and/or compression connection means.
预计接线端子50、70可直接连接到报警器或其它电子装置，或可将接线端子50、70连接到发射装置，从而可以传输到远程报警器或其它电子装置。另外，预计电解质传感器100可具有一个以上的感应表面，由此有机硅基底110可包含一个以上的表面，可在所述表面上布置具有相同或不同轨迹图案的弹性体轨迹电极。It is contemplated that the terminals 50, 70 may be connected directly to an alarm or other electronic device, or that the terminals 50, 70 may be connected to a transmitter so that transmission to a remote alarm or other electronic device is possible. Additionally, it is contemplated that electrolyte sensor 100 may have more than one sensing surface, whereby silicone substrate 110 may include more than one surface on which elastomeric trace electrodes having the same or different trace patterns may be disposed.
所述正负导电弹性体轨迹电极150、170可通过将正负电极150、170分开的间隙或通道120进行设置。所述间隙或通道距离的大小被定义为正极150(或其部分)与最近的负电极170(或其部分)之间的距离。所述轨迹电极150、170 之间的间隙或通道距离的大小可定义为功能大小，该大小由电极的导电性能决定，以在正负导电弹性体轨迹电极150、170之间迅速形成电路桥接。鉴于没有电解质，该间隙或通道大小将使得电路仍处于断开状态。The positive and negative conductive elastomeric trace electrodes 150 , 170 may be disposed through a gap or channel 120 separating the positive and negative electrodes 150 , 170 . The size of the gap or channel distance is defined as the distance between the positive electrode 150 (or portion thereof) and the nearest negative electrode 170 (or portion thereof). The size of the gap or channel distance between the trace electrodes 150, 170 can be defined as a functional size, which is determined by the conductive properties of the electrodes to quickly form a circuit bridge between the positive and negative conductive elastomer trace electrodes 150, 170. Given the absence of electrolyte, this gap or channel is of such a size that the circuit remains open.
预计电解质不仅可使相互之间只有一个间隙或通道距离的正负电极桥接，同时可以桥接具有多通道或间隙或可能采用不均匀大小间隙或通道的正负轨迹电极。因此确定地理解为轨迹电极150、170间的间隙或通道距离的实施例，以及轨迹宽度或面积的相关实施例包含的有效值，将仅由跨过特定距离并在具有一定电阻等级的承载电流的轨迹电极150、170之间给定电极导电性限定。正负轨迹电极150、170之间非限定的优选实施例包含间隙或通道的距离可以是1-20mm，轨迹宽度或直径大小的优选实施例可以是1-20mm。Electrolytes are expected to bridge not only positive and negative electrodes that are only one gap or channel away from each other, but also positive and negative track electrodes that have multiple channels or gaps or may employ gaps or channels of uneven size. It is thus definitely understood that embodiments of the gap or channel distance between the trace electrodes 150, 170, and associated embodiments of the trace width or area, contain effective values that will only be controlled by current carrying currents across a certain distance and at a certain resistance level. A given electrode conductivity is defined between the trace electrodes 150,170. Non-limiting preferred embodiments include distances of gaps or channels between the positive and negative trace electrodes 150, 170 may be 1-20 mm, and preferred embodiments of trace widths or diameters may be 1-20 mm.
同时应理解，本公开案预期在由此得到的实施例中，使用非导电性有机硅或同等材料形成很小的桥接，其设置将根据在轨迹电极150、170间建立和保持相互之间间隙或通道120或者多个间隙或通道的功能的功能性间隔。但是，本公开案的优选实施例是利用柔性非导电有机硅基底110作为分隔手段，在轨迹电极 150、170之间形成间隙或通道，由此将导电弹性体轨迹电极150、170安装到柔性非导电有机硅基底110上，其安装方式使间隙或通道设在它们之间。由此将轨迹电极150、170安装到柔性非导电有机硅基底110上的安装方法是热成型。导电弹性体轨迹电极150、170以及有机硅基底110的优选组成如下表中所示：It should also be understood that the present disclosure contemplates the use of non-conductive silicone or equivalent material to form very small bridges in the resulting embodiments, the arrangement of which will be based on establishing and maintaining a mutual gap between the trace electrodes 150, 170. Or channel 120 or a functional spacing of the function of multiple gaps or channels. However, a preferred embodiment of the present disclosure is to mount the conductive elastomeric trace electrodes 150, 170 to the flexible non-conductive silicone substrate 110 as a separation means to form gaps or channels between the trace electrodes 150, 170. The conductive silicone substrate 110 is mounted in such a way that gaps or channels are provided between them. The method of mounting the trace electrodes 150, 170 onto the flexible non-conductive silicone substrate 110 is thus thermoforming. The preferred composition of the conductive elastomeric trace electrodes 150, 170 and the silicone substrate 110 is shown in the table below:
导电弹性体Conductive Elastomer
绝缘硅橡胶基底部分(电解质传感器基底部分)Insulating silicone rubber base part (electrolyte sensor base part)
应当进一步了解的是，在本公开案中，很可能同一电解质传感器内有宽度不等的间隙或通道，而其轨迹大小也不相同。但是，在优选实施例中，轨迹电极图案中间隙或通道宽度，和/或轨迹宽度或直径应在所需的范围内，以完成给定电解质的检测。参见图2A-2K。It should be further understood that in the present disclosure, it is possible to have gaps or channels of different widths within the same electrolyte sensor, with tracks of different sizes. However, in a preferred embodiment, the gap or channel width in the trace electrode pattern, and/or the trace width or diameter should be within the desired range to accomplish detection of a given electrolyte. See Figures 2A-2K.
图2A-2K所示为本公开案中电极轨迹图案的多个实例。2A-2K illustrate various examples of electrode track patterns of the present disclosure.
根据上述电极轨迹实施例的功用性定义，对于不同轨迹图案，若其导电弹性轨迹正负极间间隙或通道有相关性，则这些轨迹图案的功能作用可能是等效的。图2A-2K中示出了一些的示范性的例子200A、200B、200C、200D、200E、200F、 200G、200H、200I、200J和200K。应当理解，使用上述功能定义的轨迹图案相互等效，优选实施例更准确应被理解为一系列间隙或通道间距以及相关轨迹宽度和面积(直径)的值的范围。According to the functional definition of the above-mentioned electrode track embodiment, for different track patterns, if the gap or channel between the positive and negative electrodes of the conductive elastic track is related, the functional effects of these track patterns may be equivalent. Some illustrative examples 200A, 200B, 200C, 200D, 200E, 200F, 200G, 200H, 200I, 200J, and 200K are shown in FIGS. 2A-2K . It should be understood that the track patterns defined using the functions described above are equivalent to each other, and the preferred embodiment should more accurately be understood as a range of values for gap or channel pitch and associated track width and area (diameter).
图3是具有岛状电极图案的电解质传感器300的分解侧视图。除了线型轨迹电极，本专利中称作“轨迹电极”是包含多个间隔开的“电极岛”(本发明中称作“岛”)的电极图案设计。见图3。使用岛状图案的电解质传感器组成包含连接端子线305和315。两者接正负覆盖平面导电网格(grids)325和335，这两个网格通过基底110中的绝缘层1100相互隔开。所述平面网格325、335 具有相应的较小正负线柱327、337，两者从平面网格325、335上垂直突出，穿过绝缘材料到达基底部分110的外表面。正负突出线柱327、337在位置上相互偏移，弹性体热成型在两者之上。结果是多个弹性岛电极310和320，可通过物理和电气方式由间隙120分隔交替的柱状或非柱状正负电极，然后可充满电解质，或穿过较长距离的间隙，由此可使电路闭合。FIG. 3 is an exploded side view of an electrolyte sensor 300 having an island-shaped electrode pattern. In addition to linear track electrodes, what is referred to in this patent as a "track electrode" is an electrode pattern design comprising a plurality of spaced apart "electrode islands" (referred to herein as "islands"). See Figure 3. An electrolyte sensor composition using an island pattern includes connecting terminal lines 305 and 315 . Both are connected to positive and negative overlying planar conductive grids 325 and 335 , which are separated from each other by an insulating layer 1100 in the substrate 110 . The planar grid 325 , 335 has corresponding smaller positive and negative wire posts 327 , 337 , both protruding vertically from the planar grid 325 , 335 , through the insulating material to the outer surface of the base portion 110 . The positive and negative protruding wire posts 327, 337 are offset from each other in position and the elastomer is thermoformed over both. The result is a plurality of elastic island electrodes 310 and 320, alternating cylindrical or non-cylindrical positive and negative electrodes, which can be physically and electrically separated by gap 120, which can then be filled with electrolyte, or passed across the gap over longer distances, thereby enabling electrical circuit closure.
