“…The PID settings for controller gain, Ku, proportional gain, Kp, integral time ti, and derivative time, td, are provided in Table 3 along with the associated adjustment temperatures. For reference, the heating time for TEG B is similar to the one used by Hatzikraniotis et al [13] while that for TEG C more closely resembles the real-world conditions mentioned in Deasy et al [35]. The maximum power point is obtained when the load resistance matches the internal resistance of the TEG.…”

Thermoelectric generators, or TEGs, are solid state devices which can convert heat directly into electricity according to the Seebeck effect. When thermoelectric generators are subjected to thermal cycling they can undergo severe performance degradation. In this study, an experimental rig is constructed which is capable of thermally cycling the heat delivered to commercially available thermoelectric generators. An experimental investigation is undertaken to elucidate the effects of the cycling and heating rate on the power generation performance of the generators over time. Three generator modules of the same specifications were subjected to different heating rates. The figure of merit, the electrical power output, the effective Seebeck coefficient and the internal resistance of the generators are measured to assess the evolution of the modules' performance over 600 heating and cooling cycles. It is determined that all thermoelectric generators display power generation performance reductions, and that faster thermal cycling rates lead to both faster performance degradation and an overall greater performance drop. It is observed that the reduction of the figure of merit and power generation performance is primarily due to the increase of the internal resistance of the thermoelectric generators.

“…A subsequent pilot of 10 TEG cookstoves in Ntcheu district with 4W of electric power using significantly less expensive and more robust components was tested for 6 months (O'Shaughnessy et al 2015). A third study involving five households in Thyolo district found the successful ramping up of power was capable of generating 10Wh for charging (Deasy et al 2018).…”

Background: Traditional cookstoves that burn solid biomass are associated with inefficient burning, a high degree of household air pollution and high morbidity rates. A key barrier to the adoption of clean cookstoves has been the cost of fuels. Hence, a Thermo-Electric Generating (TEG) cookstove that used solid biomass fuels more efficiently and released less smoke was developed. The TEG cookstove also generates electricity to power small electric devices. Fifteen TEG cookstoves were distributed to villagers in the Indian state of Uttarakhand in 2019. Objective: We wanted to understand whether, after two years of distribution, TEG cookstoves were still used, what and where they were used for, their perceived impacts on health, and the barriers to their use. Methods used: We surveyed 10 of the 15 recipient households. We applied the Capability, Opportunity, Motivation-Behaviour and Behaviour Change Wheel frameworks to understand what the barriers to adoption were, and what could be done to surmount these. Results: All respondents reported lower smoke levels and most respondents reported that the TEG cookstoves required less fuelwood than their traditional cookstoves, but none had used them in the month prior to the survey. Discussion: For those whose TEG cookstoves were still usable and had not been made redundant by clean cookstoves, we found there to be physical opportunity barriers and psychological capability barriers. Physical opportunity barriers included a small inlet for fuel, limited versatility beyond cooking at low temperatures, and the availability of only one hob. To surmount these barriers, we recommend co-design to suit user needs and education emphasising visible benefits of avoided soot on kitchen walls, in addition to the health benefits.

“…According to the literature survey, various extensive reviews about stoveattached TEG systems have been presented [27,29,[111][112][113][114]. A good option is the utilisation of the stoves using water as the cooling medium of the TEG to produce the maximum electric output power.…”

Green energy harvesting aims to supply electricity to electric or electronic systems from one or different energy sources present in the environment without grid connection or utilisation of batteries. These energy sources are solar (photovoltaic), movements (kinetic), radio-frequencies and thermal energy (thermoelectricity). The thermoelectric energy harvesting technology exploits the Seebeck effect. This effect describes the conversion of temperature gradient into electric power at the junctions of the thermoelectric elements of a thermoelectric generator (TEG) device. This device is a robust and highly reliable energy converter, which aims to generate electricity in applications in which the heat would be otherwise dissipated. The significant request for thermoelectric energy harvesting is justified by developing new thermoelectric materials and the design of new TEG devices. Moreover, the thermoelectric energy harvesting devices are used for waste heat harvesting in microscale applications. Potential TEG applications as energy harvesting modules are used in medical devices, sensors, buildings and consumer electronics. This chapter presents an overview of the fundamental principles of thermoelectric energy harvesting and their low-power applications.
