A periodic change in the thickness of a crosslinked poly (4-vinyl-N-methylpyridinium chloride) gel membrane, induced by a periodic voltage change, could be performed for several hours on a microelectrode. The amplitude of the change of thickness was proportional to the applied voltage, and is dependent on the degree of crosslinking and the concentration of NaCl solutions, in which all the membranes were preliminarily equilibrated before use. Moreover, a propagating wave could be generated on the surface of the gel membranes by using a 5-electrode.
