Abstract

A strip thin-film support consisting of compact or planar interdigitated array electrodes and glass substrate is presented. A novel method of forming of s-BLM on the thin metallic film (sl-BLM) has been developed. Electromechanical characteristics of BLM were studied and the measured value of elasticity modulus perpendicular to the bilayer plane was found to change considerably with increasing dc voltage. The presented results evidence the fact that the values of E^ are are strongly influenced by the degree of roughness of the metal surface. It is shown that sl-BLM modified by electron carrier can be used as a simple pH sensor.
