As growing demands in flexible electronics such as deformable display and sensor, research in shape deformation is rapidly increasing. In contrast to conventional passive shape change in current flexible devices, dynamic shape deformation is desirable for programmable shape change with electrical control. For this dynamic shape deformation, we introduced alternate laminated structures of ferroelectric polymer actuators (FPA) and compliant electrodes with adhesive films. As results of electro-active deformation of the FPAs upon an electric signal, successful soft and electrically dynamic bendable shape deformation was observed. In compared to the single layer FPA structure, multiple layered FPAs of laminated structure was studied in terms of electro-mechanically out-of-plane bending displacement as a function of electric signals. Electrically-controlled shape bending behavior would be discussed with a direction of the electric field and a polarization of the ferroelectric polymer. |
