Introduction Materials are important in sensors and transducers [1-3].
Their size is usually small and depending on the materials used for manufacturing they can easily operate at elevated temperatures [10].
Thermoelectric power generation devices use semiconductor materials optimized for the “Seebeck effect” and take advantage of existing temperature gradients to produce energy.
Materials and methods A finite element (FE) model of the commercially available Seebeck module has been developed in the ANSYS Workbench ® (v. 14.0) FE analysis software.
Finally, for the p-type and the n-type materials, average, temperature independent material properties have been considered (Table 1).
