Novel composite piezoelectric material for energy harvesting applications

Numerical analysis of microresonator developed on the basis of PZT nanocomposite

“…Moreover, piezoelectric layer allows to control parameters of microresonators, which could assure higher functionality and accuracy of micromechanical systems. Lead oxide based ferroelectrics, represented by lead zirconate titanate (Pb(Zr,TI)O3) or PZT [3,4], polyvinylidene fluoride (PVDF) films [5,6] and zinc oxide (ZnO) films [7,8] are the three main materials used in most piezoelectric applications due to their high piezoelectric coefficients, very good flexibility and strong electromechanical coupling [9].…”
