The piezoelectric a paint in the paper is composed of Pb(Nb,Ni)O -Pb(Zr,Ti)O (PNN-PZT) powder and o 3 3 f n epoxy resin. The piezoelectric paint has been coated on an aluminum beam structure, I e r and the electrode has been made on the upper surface of the piezoelectric paint using o M silver paste. By using the aluminum structure as the opposite electrode, the poling of the PNN-PZT/Epoxy paint has been conducted successfully at r
