DESIGN AND ANALYSIS OF PIEZOELECTRIC NANOGENERATOR

Abstract

In this project, This work focused is to developing size dependency-based nano
energy harvesters. I have chosen the beam with Bimorph Energy harvesters for the tip and midpositioning
of masses. The performance analysis with load resistance, quality factor, inertia
factor, excitation amplitude, etc, are analyzed and recorded in the form of voltage output and
power output. The same mathematical model can be used for different boundary conditions using
the basic equation of the strength of material for calculating the stiffness or natural frequency of
the desired structure. After all, previous performance analyses for the two models analytically
explained are validated with the COMSOL. In the last section, experimental realization is well
explained on the basis of the nano thickness of the Bimorph section. We assume that the
analytical results where voltage produced by 1 nanogeneretor but for experimental purpose
length and width are taken in micro-level, or you can say the combination of the large
number of nanogeneretor while the thickness is taken in nanoscale for experimental purpose.
Using this work, you can analyze the performance analysis of a nanogenerator with a
different configuration of the structure and their effect on voltage generation, especially In
the nanoscale, As per this work, researchers gain good knowledge to design a nano energy
producing device for various areas of applications.
