Electrical Generator Made of Aligned BaTiO3 Nanofibers

Mechanical energy scavenging from ambient environments is an attractive renewable source of power for various applications. In this work, biocompatible Pb-free ceramic nanofibrous assembles were successfully prepared via electrospinning. The electrospun precursor nanofibers were in-situ stretched, poled during the eletrospinning process and aligned on the high-speed rotating collector. Moreover, XRD pattern of obtained BaTiO3 nanofibers showed well-defined perovskite peaks with higher intensity and no detectable secondary phases which are potentially used for nanogenerators.
