Abstract
In this paper, green microfibers of barium titanate precursor were prepared by the combination of Sol-Gel processing and Gel-spinning technique. The piezoelectric microfibers of ceramic BaTiO3 were sintered, with diameter of 15μm and length of 20mm, respectively. Interdigitated electrodes were printed on an epoxy resin substrate. BaTiO3 microfibers were then aligned on the interdigitated electrodes and covered with the solution of epoxy resin, so as to obtain Inter-Digitated Electrodes Piezoelectric Fiber/polymer Composites, IDEPFC. The periodic output voltages with maximum value of 0.86V were obtained under harmonic excitation, by using a finger to apply a dynamic load on the top of the IDEPFC. ? 2011 IEEE.
