Designing and Fabricating a Prototype of the Elastic Thermoelectric Generator

The elastic thermoelectric generator (ETEG) was fabricated by using 27 couples of n-Bi 2 Te 3 and p-Sb 2 Te 3 bulk thermoelectric materials in size of 3 × 3 × 5 mm 3 on silicone substrate and using copper plate for electrodes. It was found that the open circuit voltage shows maximum value of 46.74 m...

Description
Summary:The elastic thermoelectric generator (ETEG) was fabricated by using 27 couples of n-Bi 2 Te 3 and p-Sb 2 Te 3 bulk thermoelectric materials in size of 3 × 3 × 5 mm 3 on silicone substrate and using copper plate for electrodes. It was found that the open circuit voltage shows maximum value of 46.74 mV at temperature difference 13.85 K. External load resistances were apply in the measurement and varies for obtaining the maximum output power. The matched load resistance is 0.22 Ω obtaining maximum power about 3.46 mW at temperature difference difference of 13.85 K. The output power, voltage and current were increased with temperature difference increasing and show maximum values about 35.19 mW, 27.82 mV and 126.36 mA at temperature difference 12.75 K.
