Abstract

We discuss the dynamic electromechanical behavior of barium titanate (BT) unimorph cantilevers with sensing, grounding and driving electrodes under alternating current (AC) electric fields. A three-dimensional finite element analysis (FEA) was performed to predict the deflection and output voltage in the BT unimorph cantilevers. The deflection and output voltage were also measured, and numerical results were compared with measured values. The deflection, output voltage and output power were then examined in detail.
