[0049] In a first aspect, embodiments of this application provide an electrode testing fixture without terminals, the electrode testing fixture comprising: a plurality of first substrates 100 and a plurality of second substrates 200. Figure 1 This is a schematic diagram of the planar structure of the first substrate in an electrode testing fixture according to an exemplary embodiment, as shown below. Figure 1 As shown, the first substrate 100 includes a plurality of first conductive contact areas 101. Each first conductive contact area 101 extends through the upper and lower surfaces of the first substrate 100. The first conductive contact area 101 includes a first conductive line. Different first substrates 100 are connected through the first conductive contact areas 101, and different first conductive contact areas 101 are electrically connected. Figure 2 This is a plan view of the last group of first substrates according to an exemplary embodiment, such as... Figure 2As shown, when the first substrates 100 are connected sequentially in the connection order, the last two first substrates 100 are connected to the second substrate 200 through an electrocardiogram electrode pair. There is no physical conductive line connecting the first conductive contact area 103 between different first substrates 100.
[0050] Figure 3 This is a schematic diagram of the planar structure of the second substrate in an electrode measuring fixture according to an exemplary embodiment, as shown below. Figure 3 As shown, the second substrate 200 includes a plurality of second conductive contact regions 201. Each second conductive contact region 201 extends through the upper and lower surfaces of the second substrate 200, and the first conductive contact region 101 and the second conductive contact region 201 are spatially aligned with each other. That is, when the first substrate 100 and the second substrate 200 are in use, the first conductive contact region 103 and the second conductive contact region 203 are aligned with each other. The second conductive contact region 201 on the upper surface of the second substrate 200 includes a second conductive line. The second substrates 200 are connected to each other through the second conductive contact regions 201, and different second conductive contact regions are electrically connected. Figure 4 This is a plan view of the first group of second substrates according to an exemplary embodiment, as shown below. Figure 4 As shown, when different second substrates 200 are connected in sequence according to the connection order, the first second substrate 200 is connected to the corresponding first substrate 100 by means of an electrocardiogram electrode, and the second second substrate 200 is connected to the corresponding first substrate 100 by means of an electrocardiogram electrode. There is no physical conductive line connecting the two second substrates 200 in the second conductive contact area 203.
[0051] Figure 5 This is a schematic diagram illustrating the bonding of a first substrate and a second substrate via ECG electrodes according to an exemplary embodiment, as shown below. Figure 5 As shown, in the first substrate 100, the first conductive contact area 101 on the lower surface is attached to the first surface of the ECG electrode pair 80. In the second substrate 200, the second conductive contact area 201 on the lower surface is attached to the second surface of the ECG electrode pair 80 to connect the first substrate 100 and the second substrate 200.
[0052] For several ECG electrode pairs, the lower surface of the first substrate 100 is attached to the first surface of the ECG electrode pair, and the lower surface of the second substrate 200 is attached to the second surface of the ECG electrode pair. The positions where the ECG electrode pairs are attached to the first substrate 100 and the second substrate 200 correspond to the first conductive contact area 101 and the second conductive contact area 201. When power is supplied to the first conductive contact area 101 starting in the first substrate 100, the ECG electrode pairs connect the first substrate 100 and the second substrate 200, forming a closed conductive circuit. This allows current to flow between the first substrate 100 and the second substrate 200 through each electrode according to the first and second conductive circuits, thereby applying a preset bias current to each ECG electrode pair for rapid testing.
[0053] By simultaneously testing multiple ECG electrode pairs using this application, the testing cycle for multiple ECG electrode pairs can be reduced to the testing cycle required for a single ECG electrode pair, significantly improving testing efficiency. Furthermore, this application uses the first substrate 100 and the second substrate 200 to bond the ECG electrode pairs, creating a sealed environment for them, thereby avoiding impedance abrupt changes caused by environmental factors and improving the accuracy of the test results.
[0054] In one embodiment, Figure 6 This is a schematic diagram of the structure of a first substrate according to an exemplary embodiment, such as... Figure 6 As shown, the first substrate 100 includes an upper surface 102 and a lower surface 105. The first conductive contact region 101 in the first substrate 100 includes a first contact region 103 and a first through hole 104. The first through hole 104 is provided on one side of the first contact region 103, and the area of the first contact region 103 is larger than the area of the first through hole 104. Conductive material is sprayed into the first contact region 101 on both the upper and lower surfaces of the first substrate 100. Figure 7 This is a schematic diagram of the structure of a second substrate according to an exemplary embodiment, such as... Figure 7As shown, the second substrate 200 includes an upper surface 202 and a lower surface 205. The second electrical contact region 201 in the second substrate 200 includes a second contact region 203 and a second through hole 204. A second through hole 204 is provided on one side of the second contact region 203. The area of the second contact region 203 is larger than the area of the second through hole 204. The second through hole 204 and the first through hole 104 are spatially aligned. The first conductive contact region 103 and the second contact region 103 are also spatially aligned. Conductive material is sprayed into the second contact region 203 within the upper surface 202 and the lower surface 205 of the second substrate. Conductive material is sprayed into the second through hole 204 within the upper surface 202 of the second substrate. The second through hole 204 is connected to the second contact region 203 via a second conductive line. The conductive material allows externally applied current to flow between different second contact areas 203, first contact areas 103, and ECG electrode pairs via first and second conductive paths, so that current flows through each ECG electrode pair.
[0055] The first through hole 104 and the second through hole 204 are spatially aligned, and a conductive material is sprayed onto the second through hole 204 on the upper surface 205 of the second substrate. It should be noted that, based on the dimensions of the first contact area 103, the second contact area 203, and the ECG electrode pair, the distance from the center of the first through hole 104 to the center of the first contact area 103 is such that when the ECG electrode pair is attached to the first contact area 103, the ECG electrode pair cannot cover any boundary or opening of the first through hole 104. Similarly, the distance from the center of the second through hole 204 to the center of the second contact area 203 is such that when the ECG electrode pair is attached to the first contact area 103, the ECG electrode pair cannot cover any boundary or opening of the second through hole 204.
[0056] When testing the drift voltage of each ECG electrode pair, for any given ECG electrode pair, one probe of a voltmeter is passed through a first through-hole 104 adjacent to a first contact area 103 that contacts the ECG electrode pair, reaching a second through-hole 204 and contacting the conductive material on the second through-hole 204. The other probe of the voltmeter is placed on the first contact area 103 that contacts the ECG electrode pair to detect the offset voltage of the ECG electrode pair pressed together by the first contact area 103 and the second contact area 203.
[0057] It should be noted that the conductive material can be selected from various metal-based pastes, including copper paste and silver paste. Based on its good conductivity and stability, silver paste is preferably selected as the conductive material. The conductive material is sprayed onto the first contact area 103, the second contact area 203, the second through-hole 204 in the second substrate upper surface 205, and the conductive lines connecting each contact area. The conductive material establishes an electrical connectivity architecture between the contact areas to determine the overall connectivity of the test. Furthermore, by contacting the ECG electrode pairs with the conductive material, the resistance fluctuations caused by poor contact with terminalless ECG electrode pairs using traditional alligator clips are eliminated, ensuring the accuracy of the ECG electrode pair test data and accurately reflecting the performance of the ECG electrode pairs.
[0058] In another embodiment, in any one of the first substrates 100, the first conductive contact areas 101 are arranged in a top-to-bottom order. A conductive path is formed between two first contact areas 103 by spraying conductive material in a top-to-bottom order. No conductive material is sprayed between the second and third first contact areas 103; instead, the conductive path is led from the first substrate 100 to the second substrate 200 through the second first contact area 103 and the ECG electrode pair. In the second substrate 200, the second conductive contact areas 201 are arranged in a top-to-bottom order, and the second contact areas 203 are spatially aligned with the first contact areas 103. Therefore, when the ECG electrode pair leads the conductive path from the first substrate 100 to the second substrate 200, the current from the first contact areas 103 in the first substrate 200 is received through the second contact areas 203. Thus, a conductive path is formed between the second and third second contact areas 203 on the upper surface 205 of the second substrate by spraying conductive material. In the manner described above, different conductive paths are formed between the first contact areas 103 and between the second contact areas. Each pair of first contact areas 103 and second contact areas 203 are connected only once. If the same contact area needs to be connected a second time, the second connection is transferred to another substrate through the ECG electrode pair. The corresponding contact areas are connected in order from top to bottom to form a conductive path between the first substrate 100 and the second substrate 200, thus completing the conduction of the ECG electrode pair.
[0059] Conductive paths also exist between different first substrates 100 and between different second substrates 200. This enables simultaneous testing of more ECG electrode pairs. All first substrates 100 are arranged from left to right. An unconnected first contact area 103 exists on the upper surface of the first substrate 100. Conductive material is sprayed onto the unconnected first contact area 103 and the first contact area 103 at the same position on the adjacent first substrate to the right, forming a conductive path. All second substrates 200 are arranged from left to right. If an unconnected second contact area 203 exists on the upper surface of the second substrate 200, conductive material is sprayed onto the unconnected second contact area 203 on the second substrate and the second contact area 203 at the same position on the adjacent second substrate to the right, forming a conductive path.
[0060] A plurality of first substrates 100 and a plurality of second substrates 200 are connected by conductive paths, and conductive connections are formed between the first substrates 100 and the second substrates 200 through ECG electrode pairs. By forming conductive paths between the first substrates 100 and the second substrates 200, and between the first substrates 100 and the second substrates 200, a synchronous testing architecture is formed. In this synchronous testing architecture, current testing can be performed by connecting multiple ECG electrode pairs in series, and the stability of the ECG electrode pairs during long-term testing is ensured.
[0061] In another embodiment, the connection methods between different first substrates 100 and different second substrates 200 include:
[0062] All first substrates 100 are arranged from left to right. If all the first contact areas 103 on the upper surface of the first first substrate 100 are connected, conductive material is sprayed between the last first contact area 103 in the first substrate 100 and the first contact area 103 at the same position in the adjacent first substrate to the right, forming a conductive path. All second substrates 200 are arranged from left to right. If all the second contact areas 203 on the upper surface of the second second substrate 200 are connected, conductive material is sprayed between the first second contact area 203 in the second substrate 200 and the second contact area 203 at the same position in the adjacent second substrate to the right, forming a conductive path. Through this method, the connection between different first substrates 100 and the connection between different second substrates 200 are achieved.
[0063] In another embodiment, Figure 8 This is a schematic diagram of the structure of an electrode testing fixture according to another exemplary embodiment, such as... Figure 8As shown, for 27 ECG electrode pairs, nine first substrates 100 and nine second substrates 200 are configured. Three target contact areas exist on the upper surface 102 of any one of the first substrates and the upper surface 202 of any one of the second substrates. The first lower target contact area 211 is electrically connected to the first conductive area 60 so that current flows into the first upper target contact area 211 by connecting a positive power supply to the first conductive area 60. The twenty-seventh upper target contact area 137 is electrically connected to the second conductive area 70 so that current flows through the first substrate 100 and the second substrate 200, forming a closed current loop for the ECG electrode pairs by connecting a negative power supply to the second conductive area 70. The first substrate 100 is arranged in a left-to-right order. In the first upper target substrate 10, the first upper target contact area 111 and the second upper target contact area 112 are connected by a conductive path. The second upper target contact area 112 is also used to connect the second lower target contact area 212 through an electrocardiogram electrode pair, thereby connecting the first upper target substrate 10 and the first lower target substrate 20. In the first lower target substrate 20, the second lower contact target area 212 is connected to the third lower target contact area 213. The third lower target contact area 213 is also used to connect the first upper target contact area 113 through an electrocardiogram electrode pair. The first upper target contact area 113 is also used to connect the fourth upper target contact area 114 in the second upper target substrate 11. The fourth upper target contact area 114 is also used to connect the fourth lower target contact area 214 through an electrocardiogram electrode pair, thereby connecting the second upper target substrate 11 and the second lower target substrate 21. In the second lower target substrate, the fourth lower target contact area 214 and the fifth lower target contact area 215 are connected via a conductive path. The fifth lower target contact area 215 is also used to connect the fifth upper target contact area 115 via an electrocardiogram electrode pair, thereby connecting the second upper target substrate 11 and the second lower target substrate 21. The fifth upper target contact area 115 and the sixth upper contact area 116 are connected via a conductive path. The sixth upper target contact area 116 is also used to connect the sixth lower target contact area 216 via an electrocardiogram electrode pair, thereby connecting the second upper target substrate 11 and the second lower target substrate 21. In the second lower target substrate 21, the sixth lower target contact area 216 is also used to connect the seventh lower target contact area 217 in the third lower target substrate 22. The seventh lower target contact area 217 is also used to connect the third upper target substrate 12 and the third lower target substrate 22 via an electrocardiogram electrode pair. In the third upper target substrate 13, the seventh upper target contact area 117 and the eighth upper target contact area 118 are connected by a conductive path. The eighth upper target contact area 118 is also used to connect the eighth lower target contact area 218 through the electrocardiogram electrode pair, so as to connect the third upper target substrate 12 and the third lower target substrate 22.In the first lower target substrate 22, the eighth lower target contact region 218 and the ninth lower target contact region 219 are connected via a conductive path.
