Abstract

Barium titanate prepared by two step sintering method is preferred for its small grain size approximately 1 µm and high piezoelectric constant 470. In this paper, finite element analysis (FEA) is performed to quantitatively determine the influence of external applied stress on the generated surface potential and polarization effect for both poled and unpoled BaTiO<subscript>3</subscript>. The modeling simulation verified that poled BaTiO<subscript>3</subscript> is approximately 1.5 times more responsive to applied stress. The results also indicate that the maximum surface potential is generated when stress is applied parallel to the direction of electric dipole. [ABSTRACT FROM AUTHOR]
