Abstract: |
The invention relates to a resistance chromatography imager based on micro electrode, and relative micro-cut measurement, wherein it uses micro electrode to span the horny layer with high resistance; it can replace traditional surface electrode, to be used as current activator and sensor to sense voltage signal; the measured signal via magnification and filter is input into PC to be processed and displayed via gray diagram or colorful diagram, to represent the resistance distribution. The invention can reduce the effect of skin resistance in current activation and voltage signal collection, with high signal-noise ratio and reduced error, to improve the calculation accuracy and image resolution. |
