Paper Abstract

Interdigitated electrodes are used to obtain an in-plane d33 coupling from patch actuators. Existing design tools do not take into consideration the three dimensional effects of polarization reorientation. This work presents a 3-D finite element code that utilizes a micromechancial constitutive law with full ferroelectric switching. The code is used to explore the design of interdigitated electrode devices. The results point to several parameters that are important to the design of these devices. These include electrode spacing, electrode width, specimen thickness, and specimen depth.
