Poling, the process of applying an electric field to activate and orient a material's piezoelectric response in a preferred direction, is an essential step in the manufacture of ferroelectric ceramics for use in smart devices. In this work finite element techniques are used to calculate electric field and stress. Poling, the process of applying an electric field to activate and orient a material's piezoelectric levels resulting from the poling process. The effects of electrode spacing, material condition and the strength and sequencing of applied fields during poling are examined using computational experiments. The material section evaluated is a thin panel of PZT-5A ceramic.
