Piezoelectric barium zirconate-titanate ceramic nanofibers were prepared by combination of Sol-Gel processing and electrospinning technique. The average diameter of barium zirconate-titanate ceramic nanofibers is nearly 200 nm. The x-ray diffraction pattern of the fibers showed that their crystalline structures displayed tetragonal perovskite structures. Interdigitated electrodes were sprayed on an epoxy resin substrate. BaTi0.9Zr0.1O 3 nanofibers were then aligned on the interdigitated electrodes and covered with the solution of epoxy resin, so as to obtain Piezoelectric Fiber/polymer Composites. The periodic output voltages with maximum value of 0.26V were obtained under harmonic excitation, by using a finger to apply a dynamic load on the top of the composites. 漏 (2012) Trans Tech Publications.
