This paper deals with modal control of one-dimensional planar structures using both distributed-parameter film sensors and actuators with a view to extracting as well as suppressing the designated structural vibration mode. First the fundamental properties of a modal control system based upon distributed-parameter sensors and actuators are discussed. It is shown that the utilization of distributed-parameter sensors and actuators leads to the elimination of spillover destabilization. A photo-resist technique on electrode patterning of a PVDF film and a laminating technique are then introduced, hence termed a multi-layer PVDF film. The use of the multi-layer PVDF film per se is found to possess the potential of modal control. Furthermore, a multi-layer PVDF film-based one-dimensional planar structure is developed, which has the attribute of modal control. The experiment is finally conducted, demonstrating the capability of modal control for suppressing the structural mode of interest without causing any spillover effect on the other structural modes.
