dc.description.abstract |
Due to recent developments in energy harvesting,
there has been a subsequent rise in MEMS (Micro
electromechanical systems) powered by low-frequency vibrations
in the environment through effective transduction procedures like
piezoelectricity. In this paper, a vertically integrated single
piezoelectric Zinc Oxide nanowire-based system is modelled for
energy harvesting applications. To reinforce this development,
different structures of nanogenerators were modelled and
simulated using COMSOL Multiphysics 5.3 software for their
performance upgrades. It was developed to analyse the
compression and bending effect of the nanowire. To compare and
validate the induced piezoelectric output, mathematical equations
were derived using piezoelectric constitutive equations. Moreover,
the voltage output of the nanowire under a constant lateral force
was analysed varying with the nanowire dimensions in terms of
aspect ratio. The analysis results have shown that the compression
of ZnO nanowire gives more output voltage compared to the
bending of the nanowire for the same nanogenerator. The
theoretical and simulation results also prove that the length of the
nanowire does not influence the piezoelectric potential in a lateral
bent nanowire. |
