ABSTRACT: In order to survive in this modern world,
electricity is an essential thing. Electricity allows us to power the
technology we use every day. Without electricity, people can’t imagine their
lives. As a developing country, Bangladesh still lacks electricity every day.
The electricity supply to the rural areas is very poor. It is known that energy
can be converted from one form to another form. As noise is the energy, it can also be converted into various forms of energy. Noise can
be represented as a sound that is loud or unpleasant
and causes disturbances such as street traffic sounds, construction sounds,
airports, etc. Using a suitable transducer, noise (sound) energy can be
transferred into a viable source of electricity generation. This can be
accomplished by employing a transducer and converting noise-induced vibrations
into electrical energy. Our main goal is getting enough energy, reducing the
pressure of the main grid of electricity and decreasing fossil fuel imports.
This paper presents the design and investigation of an energy harvesting system
from noise. In this paper, an application is designed to get energy from noise
by using a speaker as a transducer. Voltage has been stepped up by using a
transformer, a diode which gives DC value which can be tapped into a battery
and provide energy from the battery when it is needed. The embedded device was
initially tested by clapping hands and tested further by using car horns. The
vibrations created by car horns and other noises have been converted into
electrical energy through the principle of electromagnetic induction. In total,
the application produced optimal results of 0.5 - 1.0 volts which were stepped up using a transformer while maintaining the
whole system being low cost and user-friendly.
