Problems solved by technology

[0006] However, the ion current detection system in the prior art can only image on a plane, which will lead to inaccurate ion current detection results, and cannot realize large depth of field detection; cannot realize multi-directional observation; and has no imaging stereoscopic effect
It is not conducive to accurate positioning of the relative position of the microelectrode and the sample to be measured

Description

technical field [0001] The invention relates to micro-measurement technology, in particular to a dynamic ion current detection system. Background technique [0002] The existing non-destructive measurement technology is under the control of a computer, using microelectrodes to test the local micro-region information of the sample in a non-destructive way without contacting the sample, such as the concentration of ion molecules entering and leaving the sample, the flow rate and the flow direction information, the surface of the sample local currents, etc. Microelectrodes with different characteristics are used to measure different information: For example, selective / specific molecular microelectrodes are used to measure ion molecular flow information in and out of samples. The types of microelectrodes include glass microelectrodes, metal microelectrodes, carbon fiber microelectrodes, etc., and the ions that can be measured Enzi types include H+, Ca 2+ 、H + 、K + , Mg 2+ ,...
