En los últimos años la tendencia en el desarrollo emergente de biosensores autónomos y portátiles han propiciado la búsqueda de nuevos materiales, además del diseño de nuevas estructuras que generen su propia energía de manera eficiente y con alto rendimiento para asegurar el suministro energético a largo plazo, eliminando el uso de baterías externas. De los materiales más estudiados encontramos a los triboeléctricos, piezoeléctricos, termoeléctricos y piroeléctricos, materiales que han tenido mayor biocompatibilidad con los parámetros fisiológicos del cuerpo humano para la generación de energía. En este trabajo se propone ilustrar el proceso sistemático en un software de simulación de elementos finitos del material triteleluro de dibismuto (Bi2Te3), considerado como uno de los más eficientes en la generación de energía termoeléctrica. Las simulaciones implementadas en COMSOL MultiphysicsⓇ, demuestran la correlación entre el diseño físico-mecánico de las estructuras y la eficiencia energética, permitiendo la determinación de las características y parámetros esenciales para su futura fabricación. Los resultados demuestran que, con un número mayor de termopares, incluso cuando las dimensiones son inferiores tomando como referencia la temperatura superficial del cuerpo humano, aumenta la potencia generada de las estructuras evaluadas.
