Title: Evaluation of piezoelectric paints as vibration and acoustic emission sensors

Abstract

Piezoelectric paints were prepared using lead zirconate titanate (PZT) ceramic powder as a pigment and epoxy resin as a binder. The obtained paints were coated on aluminum test specimens, and were cured at room temperature or at 150 C, thus forming the paint films having thicknesses of 25 to 300 {micro}m and a PZT volume fraction of 53%. These films were then poled at room temperature, and were evaluated with regard to the sensitivities as vibration and acoustic emission sensors in the frequency ranges of 0--25 Hz and 0--1.2 MHz, respectively. The paint film sensitivity obtained under a given poling field depends on the film thickness, the cure temperature, and the PZT/epoxy composition in the pigment paste (an intermediary product of the final paint). A good correlation is found between the sensitivity and the electrical conductivity for all the paint films studied, thus indicating that the actual poling field acting on the PZT particles dispersed in epoxy resin is determined by the electrical conductivity of the paint film.
