“…The article concluded that the inclusion of Thomson heat is imperative when modeling thermoelectric devices, and that the analytic model's thermal and electrical performance predictions are sufficient for the thermal-electric characterization of unicouples with interconnectors that operate under certain conditions. Sreekala et al [24] studied the functioning of coil guns, which use the electrical energy harvested from a bio-thermal energy harvester to fire multifunctional bullets, thus allowing them to be reused in an emergency without exploding. They used the Ansys model to study thermoelectric energy harvesting, which can be used to power specialized applications like medical devices by using the heat produced by the human body.…”

Thermoelectric generators are devices that transform thermal energy into electric energy. These devices play an influential role in our constantly developing civilization due to their energy conversion capabilities and advantages over other conventional methods. The material properties and thermoelectric phenomena are paramount to the design process of such devices. The design process must have a complex tool to model all the thermoelectric phenomena, such as, for example, the commercial numerical code of Ansys Mechanical. However, these numerical tools can be methodologically and computationally demanding. Thus, this study aims to develop a methodology through which to characterize thermoelectric generators by using a simplified one-dimensional numerical model that considers temperature-dependent N- and P-type material properties and convective heat losses. The proposed model’s results are compared and validated to a single thermoelectric leg and a complete thermoelectric commercial module, both modeled in Ansys Thermal-Electric. These results consider the different values for electric and thermal loads as current densities, electric resistivities, and heat transfer coefficients. The main result of this study is the correct prediction of the output voltage and output power given by the one-dimensional proposed model, which was validated against a comprehensive model and the commercial thermoelectric module’s information. Therefore, the proposed methodology of this study provides a deeper understanding of the thermoelectric energy conversion process, and it can guide the design and optimization of thermoelectric generators for practical applications.
