Abstract
This thesis reports the development of simulation on how to harvest energy from wasted
heat by using thermoelectric generator. The simulation is run in MATLAB software to
show the output of the energy harvesting system by comparing within different model of
thermoelectric generator used. The purpose of comparing each result between different
models of thermoelectric generator is to study how to optimize the energy harvesting
system which one of the objective of the project. The objectives of the project apart from
optimization of the energy harvesting system is to design a system that harvest wasted heat
and turn it into electricity. The system design is tested in MATLAB software to simulate
the output of the design. The development of the simulation is started with study on the
mechanism of the thermoelectric itself. It is to understand more on how the electricity can
be generated from the wasted heat and take notes on any factor that affecting the efficiency
of the system in aspect of the output, industry availability and also cost. The findings show
that the best material for thermoelectric generator for daily and common uses is compound
of Bismuth and Tellurium or called as Bismuth Telluride. This compound is a
semiconductor that can work finely at high temperature of as high as 330 C֯ heat sources
continuously and up to 400 C֯ intermittently.
