Abstract

This paper studies the dynamic electromechanical response of 1-3 piezoelectric/polymer composites under alternating current(AC) electric fields. The piezocomposites contain square or circular piezoelectric rods in an epoxy matrix. Experiments were conducted to measure the electrical impedance and phase angle at various frequencies, using the device specimen of the 1-3 piezocomposites. Three dimensional finite element analysis was also employed to calculate the frequency characteristics, and a comparison is made between simulation and experiment. The dynamic electromechanical fields in the 1-3 piezocomposites are then discussed in detail.
