Owing to the polarization of ions in a crystal that has noncentral symmetry, a piezoelectric potential (piezopotential) is created in the material by applying a stress. The creation of piezopotential together with the presence of Schottky contacts are the fundamental physics responsible for a few important nanotechnologies. The nanogenerator is based on the piezopotential-driven transient flow ...

Abstract With the development of technology, self-powering devices by harvesting bioenergy is an efficient way to achieve sustainable system operation. In this paper, we fabricated a flexible hybrid nanogenerator (HNG) based on multilayer nanocomposites, innovatively using biocompatible Polylactic acid (PLA) as piezoelectric material and multi-walled carbon nanotubes (MWCNTs) polydimethylsiloxa...

We have demonstrated an innovative approach to convert mechanical energy into electrical energy by piezoelectric zinc oxide nanowire (NW) arrays. The mechanism of the nanogenerator (NG) relies on the coupling of piezoelectric and semiconducting dual properties of ZnO as well as the elegant rectifying function of the Schottky barrier formed between the metal tip and the NW. Alexe et al. have rec...
