摘要
为了研究银、铂、玻碳、金、铜电极的极化特性,确定每种材料电极的最佳应用场景,对表面微电极型式进行了详细的理论分析、模型仿真和水槽测量研究,获得了一种表面微电极材料极化阻抗评测方法。结果表明,铂和玻碳电极测量准确度最优,银电极性能稍次于铂和玻碳电极,金电极仅在50 kHz以上可以适用。综合准确度、灵敏度和可靠度,玻碳电极综合性能最优,其余依次为银、铂、金、铜电极。铂和玻碳电极更适合于阻抗谱应用,银、铂和玻碳电极非常适合于电阻抗扫描或断层成像。单频电阻抗测量频率较低时可选择银、铂和玻碳电极,频率较高时可选择金、铂和玻碳电极。
In order to study the polarization characteristics of silver, platinum, glassy carbon, gold and copper electrodes and determine the best application scenario of each material electrode, a detailed theoretical analysis, model simulation and flume measurement of surface micro-electrode types are carried out, and a polarization impedance evaluation method of surface micro-electrode materials is obtained. The results show that the measurement accuracy of platinum and glassy carbon electrode is the best, the performance of silver electrode is slightly inferior to that of platinum and glassy carbon electrode, and the gold electrode can only be used above 50 kHz. In terms of accuracy, sensitivity and reliability, the comprehensive performance of glassy carbon electrodes is the best, followed by silver, platinum, gold and copper electrodes. Platinum and glassy carbon electrodes are more suitable for impedance spectroscopy applications, while silver, platinum and glassy carbon electrodes are very suitable for electrical impedance scanning or tomography. Silver, platinum and glassy carbon electrodes can be selected for lower frequency impedance measurement, while gold, platinum and glassy carbon electrodes can be selected for higher frequency.
