The method for reconstructing the cell image of the present invention, [see the fourth figure], the set electrode is placed in the training class (8), and the guiding layer (5) of the inner edge is used to contact the object to be tested, and is transmitted to The electrical value generated by the object is calculated by two methods: the edge method and the adjacent edge method. The edge method is to add a stimulus source on both sides of the opposite side of the electrode, and the impedance can be divided into two types. : One is the rotation mode, measuring the impedance value measured by the stimulus source rotated by 180 degrees in sequence, and measuring five times in succession, the maximum occurrence occurs at the junction of the microelectrode array group, and it is found by statistical analysis that In the past, the average, maximum and minimum values of each measurement are increasing. This phenomenon, the same result is obtained by culturing m at different microelectrodes; also • the level of the liquid level of the culture dish is found. It is inversely proportional to the average value of the impedance, so the impedance value of the microelectrode culture dish is closely related to the evaporation phenomenon of the liquid surface, and the smaller the cross-sectional area of the culture dish, the more obvious the change of evaporation and impedance value. And then rotate the stimulus to the next The adjacent electrode continues to measure; the second is the relative mode, the stimulus source remains stationary, and the voltage value of the other electrode to GND is measured. Since the current can flow uniformly through the object to be tested, the 〇 and the object to be tested have a good reaction, so Better measurement results are obtained, and the shape symmetry is well evaluated. The relationship between the rotation method of the edge method and the position of the electrode is adjacent to the two electrodes plus the stimulus source, and the impedance is measured. The same as the opposite side method can also be divided into the above two ways, because the current density is concentrated around the periphery of the electrode, it can be used to detect the similarity between the electrodes, or the degree of error in the position of the electrode array, using different stimulation methods, The measured impedance values are compared with the electrode-related position map analysis, and the data is analyzed by statistical methods. The advantage is that the hollow cylindrical electrode is used to facilitate the analysis of the electrical characteristics of the cell 098133519 Form No. A0101, page 7 / 16 page 0982057384-0 201113368, and the system can improve the signal noise ratio on the measuring signal. Dividing electrode etching into 32 sets of array electrodes can improve the precision and accuracy of measurement, and increase the fineness of cell image reconstruction. It can not only quickly identify and analyze nerve cell tissue, but also quantify its morphology. In order to solve the shortcomings of time-consuming subjective and other human analysis, explore more meaningful parameters to understand the mechanism of morphological changes such as nerve cell tissue damage and death. In summary, it is known that the present invention is novel, and the present invention is not found in any publication, and is in compliance with the provisions of Articles 21 and 22 of the Patent Law. The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto.

The m-electrode array is cultured as described in claim 1, wherein the insulating layer 098133519 has the form number A0101, page 10/16 pages 0982057384-0 201113368, and the insulating layer material is nickel-phosphorus alloy, which can be isolated when energized. The replacement between the connecting layer and the electrons of the guiding layer avoids the use efficiency of the electrode. 7. The culture electrode array according to claim 1 of the patent application, wherein the guiding layer is made of gold, which can improve the conductivity and has good biocompatibility. 8. The m-electrode array is cultured as described in claim 1, wherein the guiding layer and the guiding layer thereof may be disposed on the adhesive layer to reduce the setting man-hour and cost of the connecting layer and the insulating layer. 〇 0982057384-0 098133519 Form No. A0101 Page 11 of 16
