In recent years, the trend in the emerging development of autonomous and portable biosensors has led to the search for new materials, as well as the design of new structures that can efficiently generate their own energy with high performance to ensure long-term energy supply, eliminating the use of external sources. Among the most studied are triboelectric, piezoelectric, thermoelectric, and pyroelectric materials, which have shown greater biocompatibility with the physiological parameters of the human body for energy harvesting. This paper proposes to illustrate the systematic process in a finite element simulation software of the bismuth telluride (Bi2Te3) material, considered one of the most efficient in thermoelectric energy generation. Simulations implemented in COMSOL Multiphysics demonstrate the correlation between the physical-mechanical design of the structures and energy efficiency, allowing the determination of the crucial features and parameters for future development. The results demonstrate the power generated by the material according to the surface temperature gradient of the human body for each of the designed structures.
