提出了一种基于电化学非线性信息的化学传感器的设计方法。向测试溶液施加正弦电压，并通过快速傅立叶变换（FFT）分析所得输出电流。从FFT中的高次谐波分量，电容和电导的电压依赖性进行评估。通过选择合适的金属电极，该方法可能成为一种强有力的分析工具。
We propose a novel strategy for the development of a chemical sensor based on the information of electrochemical nonlinearity. A sinusoidal voltage is applied to a test solution and the resulting output current is analyzed by the Fast Fourier transformation (FFT). From the higher harmonic components in the FFT, voltage dependences of both capacitance and conductance are evaluated. This method may become a powerful analytical tool with the selection of suitable metal electrodes.
