Abstract

The existing linear (impedance) theory of frequency response is corrected and generalized for electrodiffusion friction probes of any shape. Special attention is paid to the dynamic calibration of real electrodiffusion probes with uncertain geometry by the potentiostatic (voltage-step) transient method.
