The fluid force represents an important source in energy power. Renewable energy can be harvested from the flow using oscillated membranes composed of flexible piezoelectric device (PVDF). The deformation of PVDF caused by fluid force induces bending stresses that generate a voltage due to electrodes positioned on the surface of the materials. We designed several useful devices forced by the fluid force action at a characteristic wave motion and flow velocity and also showed some application for utilizing wave energy and uniform flow. We examined an advanced technology of electrical energy generated by fluid force using flexible piezoelectric. We also performed a numerical simulation of fluid structure interaction to evaluate relations between the deformation of PVDF caused by fluid force and electric power.
