Abstract
Electroactive polymers are active materials capable of converting electrical signals into mechanical forces. Analytical studies using ferroelectric polymers, there are increasing research es into highly flexible devices such as displacement. In addition, st udies have been conducted on the multilayer structure of EAP to improve driving force for deformable displays. In this study, a ferroelectric polymer based multilayer PVDF driving device having a sandwich structure (Electrode PVDF Electrode) was analyzed u sing theoretical structural modeling by the finite element method. We studied the behavior of strain properties and out of plane strain along the stacked EAP layer and dipole moment direction. It was also possible to achieve two layer operation by using a tensile strain and a compressive strain together. As a result, it was found that in a stacked multi layer device, the out of plane deformation of the curved tip was significantly improved compared to single layer device.
