本發明係關於一種生醫檢測技術，尤其是一種取得穩定生醫訊號且測量準確的生物資訊感測裝置。The present invention relates to a biomedical testing technology, and more particularly to a bio-information sensing device that can obtain stable biomedical signals and perform accurate measurements.
以外科手術進行血管修復後，可能發生血栓而導致感染、組織壞死，因此，在術後恢復期間應持續監測血流狀況，以即時排除可能形成的血栓。一種習知的血流偵測技術係由醫護人員手持超音波裝置從病人體外進行偵測，藉由分析反饋的音源訊號判斷血流狀況，但是，操作人員必須接受過專業訓練，且體外感測無法連續監控而需要定時重複操作，會造成醫護的沉重人力負擔。After surgical vascular repair, blood clots may develop, leading to infection and tissue necrosis. Therefore, blood flow should be continuously monitored during the postoperative recovery period to promptly eliminate any potential blood clots. One known blood flow monitoring technique involves medical staff using a handheld ultrasound device to monitor blood flow from outside the patient's body, analyzing the feedback sound signals to determine blood flow status. However, this requires specialized training, and external sensing cannot provide continuous monitoring, requiring regular repetition, placing a heavy burden on medical staff.
另一種習知的血流感測裝置係可以被植入人體，並對血管進行連續偵測，該感測裝置係可以將血流訊號由體內傳送至體外的監測儀器，惟，該感測裝置被人體組織遮蓋，而且所偵測的血流變化微弱，係導致血流訊號容易受到雜訊干擾而降低偵測準確性甚至造成診斷錯誤，而無法即時治療血栓，或因為誤診而執行不必要的手術。Another known blood flow monitoring device is an implantable device that continuously monitors blood vessels. This sensor transmits blood flow signals from inside the body to an external monitor. However, the sensor is obscured by human tissue, and the detected blood flow changes are subtle. This makes the blood flow signal susceptible to noise interference, reducing detection accuracy and even leading to misdiagnosis. This can prevent timely treatment of blood clots or lead to unnecessary surgery due to misdiagnosis.
有鑑於此，習知的血流感測裝置確實仍有加以改善之必要。In view of this, conventional blood flow detection devices still need to be improved.
為解決上述問題，本發明的目的是提供一種生物資訊感測裝置，係可以提升電容變化量及感測靈敏度。To address the above-mentioned problems, the present invention aims to provide a bio-information sensing device that can enhance capacitance variation and sensing sensitivity.

The device comprises a dielectric material comprising the packaging layer; a signal enhancement element covering the electrodes of the detection element, wherein a force-applying surface of the signal enhancement element faces the electrodes, and a force-receiving surface opposite the force-applying surface faces the object to be measured. Vibration of the object to be measured is applied to the dielectric material between the electrodes via the signal enhancement element; and a signal transmission element located on the other side of the packaging layer from the sensing section, comprising at least one coil and two transmission lines electrically connected to the at least one coil.The two transmission lines are electrically connected to the two signal lines, respectively.
據此，本發明的生物資訊感測裝置，藉由將該數個電極交錯排列而形成數個並聯電容，係可以大幅增加該偵測元件的總電容值，使該偵測元件對於微弱的生物資訊仍能夠對應產生電容值變化，係具有提升感測靈敏度的功效，另外，該增強訊號元件轉換應力對該偵測元件之介電質造成均勻形變，係可以提升檢測的準確性及可靠度。Accordingly, the bio-information sensing device of the present invention, by staggering the electrodes to form multiple parallel capacitors, can significantly increase the total capacitance of the detection element. This allows the detection element to respond to even weak bio-information signals with capacitance changes, thereby enhancing sensing sensitivity. Furthermore, the signal-enhancing element's conversion stress causes uniform deformation of the detection element's dielectric, improving detection accuracy and reliability.
其中，相鄰之二電極之間具有一交錯長度，且該二電極相隔一間隔距離，由該間隔距離及該交錯長度界定一交錯區域，該二電極與該交錯區域等效為一電容器。如此，係可以在二個電極之間形成平行板型態的電容器，係具有形成緊鄰排列之數個電容器的功效。There is a staggered length between two adjacent electrodes, and the two electrodes are separated by a spacing distance. The spacing distance and the staggered length define a staggered region. The two electrodes and the staggered region are equivalent to a capacitor. This creates a parallel plate capacitor between the two electrodes, effectively forming multiple capacitors arranged in close proximity.
其中，該數個電極的數量為n時，形成n-1個該電容器，且該數個電容器係透過該二訊號線以並聯方式電性連接。如此，該偵測元件的總電容值為該數個電容器的電容值加總，係具有提升電容變化量及感測靈敏度的功效。When the number of electrodes is n, n-1 capacitors are formed, and these capacitors are electrically connected in parallel via the two signal lines. Thus, the total capacitance of the detection element is the sum of the capacitances of these capacitors, which improves capacitance variation and sensing sensitivity.
其中，該間隔距離為0.05毫米~0.25毫米，該交錯長度為1.5毫米~5.8毫米。如此，該偵測元件係可以藉由選擇該數個電極的規格調整等效電容的電容值及該感測元件的尺寸，係具有適用於不同形狀大小之待測物件的功效。The spacing distance is 0.05 mm to 0.25 mm, and the staggered length is 1.5 mm to 5.8 mm. This allows the detection element to adjust the capacitance value of the equivalent capacitor and the size of the sensing element by selecting the specifications of the electrodes, making it suitable for test objects of varying shapes and sizes.
其中，該偵測元件及該訊號傳輸元件是可降解金屬，包括鎂、鋅、鐵；該封裝層是可降解高分子材料，包括聚羥基丁酸酯、聚癸二酸丙三醇酯。如此，使裝置在目標生物體內不會中毒或引發免疫反應，並可在一段時間後降解及被吸收，係具有提高使用安全性及降低手術負擔的功效。The detection element and signal transmission element are made of biodegradable metals, including magnesium, zinc, and iron; the encapsulation layer is made of biodegradable polymer materials, including polyhydroxybutyrate and polyglycerol sebacate. This ensures that the device will not cause toxicity or immune reactions within the target organism and will degrade and be absorbed over time, improving safety and reducing surgical burdens.
其中，該施力面上分布數個顆粒，該數個顆粒接觸該數個電極及其範圍內的介電質。如此，該數個顆粒係可以將該受力面所承受的壓力均勻散佈至該數個電極之間，係具有確實使介電質發生形變及電容值變化的功效。A plurality of particles are distributed on the force-applying surface, contacting the electrodes and the dielectric within their area. This evenly distributes the pressure exerted on the force-applying surface between the electrodes, effectively causing the dielectric to deform and alter its capacitance.
其中，各該顆粒的徑寬為30微米~50微米，相鄰二顆粒之間的距離為40微米~60微米。如此，相鄰二電極所構成電容器的範圍內可以接觸到數個顆粒，以均勻施力於電容器，係具有穩定電容值變化的功效。The diameter of each particle is 30 to 50 microns, and the distance between adjacent particles is 40 to 60 microns. This allows the capacitor formed by two adjacent electrodes to be contacted by multiple particles, applying force evenly to the capacitor and stabilizing capacitance changes.
其中，各該顆粒為四角錐體，各該顆粒之高度為15微米~70微米，且斜面角度為30度~70度。如此，各該顆粒係可以依據受力強弱變化逐漸調整對介電質造成的形變量，係具有提升檢測準確性的功效。Each particle is a quadrangular pyramid with a height ranging from 15 to 70 microns and an inclination angle of 30 to 70 degrees. This allows each particle to gradually adjust the deformation of the dielectric material based on changes in force, improving detection accuracy.
其中，該增強訊號元件是可降解高分子材料，包括聚羥基丁酸酯、聚癸二酸丙三醇酯。如此，該增強訊號元件係可以降解、被吸收及避免引發免疫反應，係具有提高使用安全性及降低手術負擔的功效。The signal-enhancing element is a biodegradable polymer material, including polyhydroxybutyrate and polyglycerol sebacate. This allows the element to be degraded, absorbed, and avoid triggering an immune response, thereby improving safety and reducing surgical burden.

為讓本發明之上述及其他目的、特徵及優點能更明顯易懂，下文特舉本發明之較佳實施例，並配合所附圖式作詳細說明；此外，在不同圖式中標示相同符號者視為相同，會省略其說明。To make the above and other objects, features, and advantages of the present invention more clearly understood, the following provides a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings. Furthermore, elements marked with the same symbols in different drawings are considered identical and their descriptions will be omitted.
請參照第1圖所示，其係本發明生物資訊感測裝置的較佳實施例，係包含一偵測元件1、一訊號傳輸元件2及一封裝層3，該偵測元件1耦合連接該訊號傳輸元件2，該偵測元件1及該訊號傳輸元件2位於該封裝層3內。Please refer to Figure 1, which shows a preferred embodiment of the bio-information sensing device of the present invention. It includes a detection element 1, a signal transmission element 2, and a packaging layer 3. The detection element 1 is coupled to the signal transmission element 2, and the detection element 1 and the signal transmission element 2 are located within the packaging layer 3.
請參照第2及3圖所示，該偵測元件1係具有數個電極11，各該電極11可以是長條狀，且該數個電極11較佳以平行交錯排列在同一平面上，並形成左、右兩組梳狀電極互相交錯，詳言之，相鄰之二電極11係分別偏左或偏右且部分段落的投影重疊，且該二電極11上下相隔一間隔距離D，使該數個電極11形成相對偏左及相對偏右的兩組電極11，而同一組的二電極11相隔至少一條另一組的該電極11及至少兩倍的該間隔距離D，又，同一組的該數個電極11係以一訊號線12電性連接在一起，且該二訊號線12較佳與該數個電極11在同一平面上，該二訊號線12可以是兩條長直導線分別位於該數個電極11的左、右兩側，使左側的該訊號線12電性連接偏左的該數個電極11，而右側的該訊號線12電性連接偏右的該數個電極11。Referring to Figures 2 and 3, the detection element 1 has a plurality of electrodes 11. Each of the electrodes 11 may be in the form of a strip, and the plurality of electrodes 11 are preferably arranged in parallel and staggered on the same plane to form two groups of left and right comb-shaped electrodes that stagger each other. Specifically, two adjacent electrodes 11 are respectively biased to the left or right and the projections of some sections overlap, and the two electrodes 11 are separated by a spacing distance D above and below, so that the plurality of electrodes 11 form two groups of electrodes 11 that are relatively biased to the left and relatively biased to the right, and the two electrodes 11 in the same group are relatively biased to the left and relatively biased to the right. 1 is separated from another set of electrodes 11 by at least one electrode 11 and at least twice the spacing distance D. Furthermore, the electrodes 11 in the same set are electrically connected together by a signal line 12, and the two signal lines 12 are preferably coplanar with the electrodes 11. The two signal lines 12 can be two long straight wires, located on the left and right sides of the electrodes 11, respectively, so that the signal line 12 on the left is electrically connected to the electrodes 11 on the left, and the signal line 12 on the right is electrically connected to the electrodes 11 on the right.
由於相鄰的二電極11之間具有一交錯長度L，且該二電極11分別電性連接不同之該二訊號線12，使該二電極11及其之間由該間隔距離D及該交錯長度L所界定的交錯區域C可以等效為一電容器，又，該數個電極11的數量為n時，可以形成n-1個該電容器，且該數個電容器係透過該二訊號線12以並聯方式電性連接，使該偵測元件1的總電容值為該數個電容器的電容值加總，即測量該二訊號線12末端係可以得到該總電容值。Because there is a crossover length L between two adjacent electrodes 11 and each of the two electrodes 11 is electrically connected to two different signal lines 12, the two electrodes 11 and the crossover region C defined by the spacing D and the crossover length L can be equivalent to a capacitor. Furthermore, when the number of electrodes 11 is n, n-1 capacitors can be formed. These capacitors are electrically connected in parallel via the two signal lines 12, making the total capacitance of the detection element 1 the sum of the capacitances of these capacitors. This total capacitance can be obtained by measuring the ends of the two signal lines 12.
請參照第2圖所示，該訊號傳輸元件2可以是平面天線，該訊號傳輸元件2包括至少一線圈21，該至少一線圈21可以由金屬導線捲繞而成，在本實施例中，該訊號傳輸元件2係具有一個矩形之該線圈21，惟，本發明不以上述該至少一線圈21之數量、形狀及圈數為限。又，該訊號傳輸元件2還可以具有二傳輸線22電性連接該至少一線圈21，該二傳輸線22分別電性連接該二訊號線12，使該至少一線圈21透過該二傳輸線22電性連接該偵測元件1，係可以將該偵測元件1所產生的電性特徵及其變化，透過該至少一線圈21所形成的天線傳輸出去。Referring to Figure 2, the signal transmission element 2 can be a planar antenna. The signal transmission element 2 includes at least one coil 21, which can be formed by winding a metal wire. In this embodiment, the signal transmission element 2 comprises a rectangular coil 21. However, the present invention is not limited to the number, shape, or number of coils 21. Furthermore, the signal transmission element 2 can have two transmission lines 22 electrically connected to the at least one coil 21. The two transmission lines 22 are respectively electrically connected to the two signal lines 12. The at least one coil 21 is electrically connected to the detection element 1 via the two transmission lines 22, allowing the electrical characteristics and changes generated by the detection element 1 to be transmitted through the antenna formed by the at least one coil 21.
請參照第1及2圖所示，該封裝層3用於包覆該偵測元件1及該訊號傳輸元件2，以避免金屬導電材料遇到受潮、腐蝕、損傷等狀況而影響電性及訊號傳遞，該封裝層3較佳為耐撓曲材料，使該封裝層3連同該偵測元件1彎曲時避免斷裂，又，該封裝層3可以是多層結構逐層堆疊，並將該偵測元件1及該訊號傳輸元件2設置於層與層之間。As shown in Figures 1 and 2, the packaging layer 3 is used to encapsulate the detection element 1 and the signal transmission element 2 to protect the metallic conductive material from moisture, corrosion, and damage that could affect electrical properties and signal transmission. The packaging layer 3 is preferably made of a flexurally resistant material to prevent the packaging layer 3 and the detection element 1 from breaking when bent. Alternatively, the packaging layer 3 can be a multi-layered structure, with the detection element 1 and the signal transmission element 2 positioned between the layers.
另外，該封裝層3對位於相鄰二電極11之間的部位可以做為該電容器的介電質，詳言之，重疊於該交錯區域C內的該封裝層3材料位於二電極11之間，而成為平行板型態的電容器，該電容器之電容值係正比於該交錯長度L及介電質的電容率，且反比於該間隔距離D，因此，相鄰二電極11交錯的比例越高、距離越靠近、該封裝層3材料的電容率越高及該數個電極11的數量越多，係能夠提高該偵測元件1的總電容值，當該偵測元件1內的介電質受到外力作用而造成電容值的變化，係可以達到數倍的電容值變化量而更容易被偵測到，係具有提升感測靈敏度的作用。In addition, the portion of the packaging layer 3 between the two adjacent electrodes 11 can serve as the dielectric of the capacitor. Specifically, the packaging layer 3 material overlapping the interleaving region C is located between the two electrodes 11, forming a parallel plate type capacitor. The capacitance of the capacitor is proportional to the interleaving length L and the dielectric constant, and inversely proportional to the spacing distance D. Therefore, the capacitance between the two adjacent electrodes is proportional to the capacitance between the two adjacent electrodes. A higher interleaving ratio of the electrodes 11, closer spacing, a higher permittivity of the packaging layer 3 material, and a greater number of electrodes 11 can increase the total capacitance of the detection element 1. When the dielectric within the detection element 1 is subjected to external forces, the capacitance change can be several times greater, making it easier to detect and improving sensing sensitivity.
請參照第4及5圖所示，進行感測時，係將該封裝層3包覆該偵測元件1的區段環繞於一待測物件T上，在本實施例中，該待測物件T可以是血管，該訊號傳輸元件2及該封裝層3的其他部位則可以植入皮膚底下，如此，當血液流動時對血管壁的震動係可以傳遞至該偵測元件1，使該偵測元件1的電容值發生變化；再利用一讀取裝置(未繪示)靠近該訊號傳輸元件2並提供電磁波，使該訊號傳輸元件2的天線得到能量以同步該偵測元件1之電容值變化，並回傳對應的電磁波訊號；藉由分析該讀取裝置所接收的訊號，係可以的到血液流動的相關資訊，用於輔助診斷是否有血栓或其他異常症狀。該待測物件T還可以是任何具有生命現象之器官或組織，本發明不以上述血管為限。Referring to Figures 4 and 5, during sensing, the portion of the packaging layer 3 covering the detection element 1 is wrapped around a test object T. In this embodiment, the test object T can be a blood vessel. The signal transmission element 2 and the rest of the packaging layer 3 can be implanted beneath the skin. Thus, when blood flows, the vibrations on the blood vessel wall can be transmitted to the detection element 1, causing the detection element 1 to The capacitance value changes. A reader device (not shown) is then placed near the signal transmission element 2 and provides electromagnetic waves, energizing the antenna of the signal transmission element 2 to synchronize with the capacitance change of the detection element 1 and transmit a corresponding electromagnetic wave signal. By analyzing the signal received by the reader device, information related to blood flow can be obtained to assist in diagnosing the presence of blood clots or other abnormalities. The object to be tested T can also be any living organ or tissue; the present invention is not limited to the blood vessels mentioned above.
請再參照第6圖所示，本發明生物資訊感測裝置還可以包括一增強訊號元件4，該增強訊號元件4係可以覆蓋在該偵測元件1之該數個電極11上，詳言之，該增強訊號元件4之一施力面4a係朝向該數個電極11，而相對於該施力面4a的另一面為一受力面4b，該受力面4b係朝向該待測物件T，如此，當該待測物件T發生震動時，該增強訊號元件4係可以由該受力面4b接收震動，再由該施力面4a對該數個電極11之間的介電質加壓造成形變，又，該施力面4a上可以分布數個顆粒41，使該數個顆粒41能夠直接接觸該數個電極11及其範圍內的介電質，係可以將該受力面4b所承受的壓力透過該數個顆粒41均勻散佈至該數個電極11之間，使該數個電極11之間的介電質能夠確實發生形變，及增加該偵測元件1的電容值變化量，以提升檢測的準確性及可靠度。Please refer to FIG. 6 again. The bio-information sensing device of the present invention may further include a signal-enhancing element 4. The signal-enhancing element 4 may cover the electrodes 11 of the sensing element 1. Specifically, a force-applying surface 4a of the signal-enhancing element 4 faces the electrodes 11, and a force-receiving surface 4b opposite to the force-applying surface 4a faces the object T to be detected. Thus, when the object T to be detected vibrates, the signal-enhancing element 4 may receive the vibration through the force-receiving surface 4b. The force-applying surface 4a applies pressure to the dielectric between the electrodes 11, causing deformation. Furthermore, a plurality of particles 41 can be distributed on the force-applying surface 4a, allowing the particles 41 to directly contact the electrodes 11 and the dielectric within their area. This allows the pressure exerted on the force-bearing surface 4b to be evenly distributed between the electrodes 11 through the particles 41, ensuring that the dielectric between the electrodes 11 is deformed. This increases the capacitance variation of the detection element 1, thereby improving detection accuracy and reliability.
請參照第3及6圖所示，各該電極11的長度較佳為2毫米~6毫米，及寬度較佳為0.1毫米~0.3毫米，該間隔距離D較佳為0.05毫米~0.25毫米，該交錯長度L較佳為1.5毫米~5.8毫米，該偵測元件1係能夠依據所偵測之該待測物件T的大小及形狀選擇該數個電極11的數量及尺寸，使該偵測元件1可以完整感測該待測物件T。又，各該顆粒41的徑寬較佳為30微米~50微米，相鄰二顆粒41之間的距離較佳為40微米~60微米。由上述規格可知，相鄰二電極11所構成電容器的範圍內可以接觸到至少16個該顆粒41，及最多約300個該顆粒41。Referring to Figures 3 and 6 , the length of each electrode 11 is preferably 2 mm to 6 mm, and the width is preferably 0.1 mm to 0.3 mm. The spacing D is preferably 0.05 mm to 0.25 mm, and the staggered length L is preferably 1.5 mm to 5.8 mm. The number and size of the electrodes 11 can be selected based on the size and shape of the object T to be detected, so that the detection element 1 can fully sense the object T. Furthermore, the diameter of each particle 41 is preferably 30 μm to 50 μm, and the distance between two adjacent particles 41 is preferably 40 μm to 60 μm. From the above specifications, it can be seen that the capacitor formed by two adjacent electrodes 11 can contact at least 16 particles 41 and at most approximately 300 particles 41.
請再參照第7~9圖所示，該數個顆粒41可以是柱體、錐體、錐台、半球體，且柱體、錐體及錐台的底面可以是圓形、矩形、三角形或其他多邊形，本發明不以該數個顆粒41的形態為限，另外，該數個顆粒41之徑寬係底面之直徑、最大邊長或最大對角線，該數個顆粒41之高度較佳為15微米~70微米，錐體及錐台的斜面角度可以是30度~70度。Referring again to Figures 7-9, the particles 41 may be in the form of cylinders, pyramids, conical cones, or hemispheres. The bases of the cylinders, pyramids, and conical cones may be circular, rectangular, triangular, or other polygonal shapes. The present invention is not limited to the shapes of the particles 41. Furthermore, the width of the particles 41 is the diameter of the base, the maximum side length, or the maximum diagonal. The height of the particles 41 is preferably 15 to 70 microns. The angle of the pyramids and conical cones may be 30 to 70 degrees.
另外，本發明的生物資訊感測裝置較佳為生物降解材料製成，使裝置在目標生物體內不會中毒或引發免疫反應，並可在一段時間後降解及被吸收，而不需再進一步開刀取出，進而避免再次手術風險。該偵測元件1及該訊號傳輸元件2可以是可降解金屬，例如：鎂、鋅、鐵；該封裝層3及該增強訊號元件4可以是可降解高分子材料，例如：聚羥基丁酸酯(PHB)、聚癸二酸丙三醇酯(PGS)。Furthermore, the bio-information sensing device of the present invention is preferably made of biodegradable materials, ensuring that it will not cause toxicity or immune reactions within the target organism. It will also degrade and be absorbed over time, eliminating the need for further surgical removal and the risk of further surgery. The detection element 1 and the signal transmission element 2 can be made of degradable metals, such as magnesium, zinc, or iron; the encapsulation layer 3 and the signal enhancement element 4 can be made of degradable polymer materials, such as polyhydroxybutyrate (PHB) or polyglycerol sebacate (PGS).
綜上所述，本發明的生物資訊感測裝置，藉由將該數個電極交錯排列而形成數個並聯電容，係可以大幅增加該偵測元件的總電容值，使該偵測元件對於微弱的生物資訊仍能夠對應產生電容值變化，係具有提升感測靈敏度的功效，另外，該增強訊號元件轉換應力對該偵測元件之介電質造成均勻形變，係可以提升檢測的準確性及可靠度。In summary, the bio-information sensing device of the present invention, by staggering the electrodes to form multiple parallel capacitors, can significantly increase the total capacitance of the detection element. This allows the detection element to respond to even weak bio-information signals with capacitance changes, thereby enhancing sensing sensitivity. Furthermore, the signal-enhancing element's conversion stress causes uniform deformation of the detection element's dielectric, improving detection accuracy and reliability.
