【 摘 要 】

Diffusion–convection impedance for a micro-band electrode placed in a Poiseuille flow was studied experimentally under microfluidic conditions. Electrochemical impedance spectroscopy (EIS) experiments performed with a fast electrochemical system show perfect agreement with a previously published quantitative analytical expression in the low frequency domain.
