Embodiment

[0050] Referring to Figures 1 to 6, the present embodiment provides a method for preparing a microelectrode membrane, and the product form of the microelectrode membrane prepared by this method can be found in Figure 3f , Figure 3g , Figure 4 . see Figure 5 , the method can include:

[0051] Step 11, forming at least one groove 40 on the temporary substrate 04, see Figure 3a .

[0052] In this step, a patterning process may be used to form grooves 40 on the temporary substrate 04 , wherein the process parameters such as the shape and quantity of the grooves 40 may be set according to actual needs.

[0053] Step 12, forming a microelectrode implant 011 in the groove 40, see Figure 3b .

[0054] Step 13, use the microelectrode crystal planting 011 to grow in the groove 40 to form the microelectrode 01, see Figure 3c .

[0055] In this step, the microelectrode 011 grows in the groove 40 , so the shape of the formed microelectrode 01 is the same as that of the groo...

Abstract

The invention provides a preparation method of a microelectrode membrane, belongs to the technical field of bioelectrodes, and can overcome the defect of low contact tightness between a microelectrodeformed by an existing microelectrode membrane preparation method and a living body. The preparation method of the microelectrode diaphragm comprises the following steps: forming at least one groove on a temporary substrate; forming a microelectrode implanted crystal in the groove; growing a microelectrode in the groove by utilizing the microelectrode implanted crystal to form the microelectrode;contacting the first substrate with one side of the temporary substrate with the groove; the microelectrode is separated from the temporary substrate to transfer the microelectrode onto the first substrate.

Description

technical field [0001] The invention relates to the technical field of biological electrodes, in particular to a method for preparing a microelectrode membrane. Background technique [0002] A microelectrode membrane generally includes a substrate and a microelectrode disposed on the substrate. A microelectrode is a miniaturized electrode, which is an electrode not larger than 200 μm in at least one dimension. Due to its small size, microelectrodes have some properties that cannot be compared with conventional electrodes, such as high current density, fast response speed, and high signal-to-noise ratio. Therefore, it is more and more widely used in biological fields such as detection and stimulation of living organisms (such as tissues and organs of humans and animals). [0003] The basic principle of using microelectrode membranes to detect and stimulate organisms is: paste the microelectrode membranes on the organisms, make the microelectrodes in them contact the organism...
