Abstract :
The AC impedance characteristics of chloridized silver-ink electrodes have been investigated. The interface impedance decreases for light deposits and increases upon further coating. There exists, therefore, an optimal chloride deposit which ensures a low interface impedance. This deposit depends on the silver ink used and on the frequency range of interest
