Vibration based energy harvesting using piezoelectric material
Abstract
Energy harvesting has been around for centuries in the
form of windmills, watermills and passive solar power systems. It
is not only restricted to the natural resources but it has widen the
tapping source to utilise the vibration which happen all around
us. In the last decade, beam with piezoceramic patches have been
used as a method to harverst energy. An energy harvester system
modelled in this paper consist of unimorph piezoelectic cantilever
beam with a tip mass. It generates electric current or voltage
from the piezoelectric strain effect due to base excitation. This
paper is aimed at developing a mathematical model of unimorph
cantilever beam with piezoelectric harvester by using Euler–
Bernoulli beam theory. The step by step analytical solution and
the simulation result are shown in the form of voltage around the
natural frequencies.
