Currently, bio-medical and automotive industries use thermoelectric module to reproduce electrical energy from wasted heat energy. Thermoelectric generator (TEG) modeling and simulation will be hashed out further in this  paper to achieve improvement. Finite element method (FEM) model, circuit equivalent model and mathematical/computer model are various methods employed to model the thermo-electric generator. Analysis of FEM modeling requires a high tier of knowledge of an engineer in material engineering. The circuit equivalent model uses the electrical circuit analogy to describe heat transfer and electrical behavior in TEG. In this work, the mathematical derivation of circuit equivalent model is used in computer models by using Simulink (Matlab). The result of the computer model can be an alternative model for electrical or electronics engineers to improve TEG performance in the future.

The need for energy consumption nowadays becomes very important things, especially the need for electrical energy. Technology to convert heat into electricity directly can be realized using thermoelectric generators. To know the thermoelectric generator performance, this study performs an investigation of thermoelectric generator operated using motorcycle exhaust heat to generate DC power. Three identical thermoelectric generators model TE-MOD-5W5V-35S were used in this investigation. To generate different high temperatures the motorcycle was run at 1600 rpm, 2100 rpm, 3100 rpm. The circuits examined were series, parallel and combination of the two. All data were recorded using DAQ MX 9714 NI data logger that was connected to the PC using LabView program. The loads used in the current measurements were a thermoelectric cooler module model SP1848 and a fan 12 V - 0.13 A. Those two loads were installed in a parallel circuit. The results show that the tests without load produce the highest voltage, while the tests with the load result in the highest power. Increasing the temperature difference increases the power, and the parallel circuit results in the biggest power but the lowest voltage. The highest voltage of 3.3 V with series circuit was attained, and the highest power of 0.133 W with a parallel circuit was also obtained.

The present scenario is like that the need of the electrical energy is growing rapidly whereas the resource availability is lagging behind the load demand due to its extinction which leads to hinder our overall generation. It has been observed that the sustainable resources have great future potential to take lead to generate power and supply demand. In the present scenario there exists a few energy resources equivalent to fuel resource. So, there must be a technology to trap the waste and unutilized heat available in the atmosphere and utilize it into the form useful electrical energy. In the current situation, waste heat in the form of thermal energy is recovered and converted into conventional electrical energy. Today, 70% of produced energy in automobiles is wasted in form of heat by exhaust gases. The main outcome of this paper is to manage the waste heat is being generated in the vehicles efficiently, by introducing the concept of “Thermo Electric Generator” (TEG) which convert the waste heat produced inside the vehicles and Re-Generate in the form electric current and give it back to the “storage unit” due to “Seebeck effect” concept.

Thermo Electric Generator is a device which Converts warmth immediately into electric electricity the usage of a phenomenon known as the "Seebeck effect”. Unlike traditional dynamic warmness engines, thermoelectric generators contain no shifting components and are absolutely silent. But for small packages, thermoelectrics can end up competitive due to the fact they are compact, easy (inexpensive) and scalable. Thermoelectric systems may be without problems designed to perform with small heat resources and small temperature difference. The main aim of this project is to use BIO-POTENTIAL as a driving source of power for the implant devices such as Pacemakers. Pacemakers usually use batteries as their power source, and when the battery's period is over, the patient has to undergo surgery to replace the batteries. By using TEG, rapidly undergoing surgery of those pacemakers’s patient can be avoided. The main objective of our project is to power implantable devices using Thermoelectric Generator and avoid further surgeries for the patient.

Least of using thermoelectric module as an electric generator in society was often because of energy which was produced by it was unstable. So we need  voltage stabilizer circuit to push up and down the voltage to certain voltage. The purpose of this final project is to design a voltage stabilizer circuit in pico scale DC voltage based on boost converter. This experiment is done by three stage there are, stabilizer experiment by adaptor, performance of thermoelectric generator and also stabilizer experiment by thermoelectric generator.The yield of the first experiment, when we gave input voltage 3 until 9 V produced 5,07 until 5,08 V, so it has 98,55% accuracy toward 5 V expect. On the second experiment, when it is given by ∆T 30, 50 and 70 °C produced 2,5, 3,04 and 3,39 V. While on third experiment, with the same ∆T produced 5,08 until 5,09 V. But, when ∆T which given by 12 °C produced only 0,8 and 0,9 V in second and third experiment, it is because of the voltage is not fulfill accupation voltage 2 until 24 V on datasheet of used IC. Relation between ∆T and Voltage (V), Current (I)  also Power (P) which was produced have positive R value 0,76 until 1, this mean that ∆T directly proportional to V,I and P. So, the higher ∆T we give, the higher V, I and P will be.Keywords : stabilizer, thermoelectric, boost converter.

Most of the energy from the vehicle is wasted in the form of heat energy and vibration. On vehicles, the largest vibration occurs in the suspension system. The development of a mechanism which can recover the vibration energy and convert it into electrical energy, named Regenerative Shock Absorber (RSA), will be detailed in this paper. The prototype of RSA which consist of gear transmission and an electromagnetic type electric generator was studied and analyzed. Electrical circuit signal conditioner / stabilizer is added into the RSA system to stabilize the output current of the generator so that the generated electrical energy can be stored in the battery of 6 volts. The characteristics of the RSA are obtained by testing the value of the damping coefficient, the energy absorbtion capacity, and the generated electrical energy before and after going through a series of signal conditioner. Experiment was also performed by measuring the acceleration response time of the sprung and un-sprung suspension system that uses RSA with damping ratio value of 0.6. From this research, it is found that RSA design with stabilizer circuit can produce more stable electric current and voltage. The measurement results show the value of the electrical voltage output through the generator is fluctuating with an average value of 15 volts and a constant 6 volts output is obtained through the signal conditioning circuit. Furthermore, the dynamic response is obtained in the form of acceleration time-value of less than 0.2 m/s2 in a corresponding ISO 2631 standard is stated very comfortable.

Malaysia night market normally operated along a temporarily closed road. No electrical power provided by the authorities and therefore hawkers need to prepare their own. Currently, they are working with gasoline-electric generator. On top of the cost incurred, they also need to consume exhaust gas and noise from the machine. Further, this situation will also affect customers. With a high percentage of the hawkers involve with cooking activities using the LPG gas stove, excess heat is one of the potential energy which can be converted into electrical energy using a thermoelectric generator (TEG). The aim of this study is to convert the excess heat available used to powered night market electrical facilities. A set of experiments was conducted utilizing five units of TEG connected in series to convert excess heat from a butane gas stove to electrical power. The temperature at both the hot and cold sides of the TEG was recorded used to analyze the effect of power produced. Two electrical parameters namely voltage and current outputs were measured used to calculate the electrical power generated. The analysis focused on the two main governing parameters namely temperature different and Seebeck coefficient toward power generated. It was found that only some amount of excess heat was converted which produced up to 46.8 mW electrical power. This is based on the high temperature recorded at the cold side of the TEG. The almost constant trend showed in temperature different was contributed to a small magnitude of the Seebeck coefficient and so for the power generated. The trend showed by the power generated was also almost constant even the temperature on the hot side keep increasing. The energy conversion process was considered success and can be further increased by increasing the number of TEG units used as well as by incorporating a cooling mechanism as practiced by many researchers.
