This paper presents a novel smart film actuator developed in the work using an electrode patterning and laminating technique. Compared to conventional point type actuators, the distributed parameter actuators have many benefits provided that they are properly designed. However, conventional distributed parameter actuators based upon a PVDF (Polyvinylidene fluoride) film are first shaped in accordance with a desired shaping function, and then attached onto a substrate, thereby causing less-accuracy and less-handling ability. To overcome such problems, this paper introduces a photo-resist technique on electrode patterning of a PVDF film and laminating technique, with the result that the multi-layer PVDF film becomes a distributed parameter actuator per se, hence shaping and attachment handling are no longer needed. Firstly, this paper overviews a two-dimensional modal actuator for exciting specific structural mode. Furthermore, a multi-layer PVDF film-based cantilever beam entailing the capability of modal actuating is developed, the validity of the proposed smart film actuator being analytically as well as experimentally verified.
