Abstract

<jats:title>Abstract</jats:title><jats:p>Thermoelectric (TE) structures based on energy harvesting technology have played a vital role in wide‐reaching applications. In this study, a composite structure consisting of a glass fabric covered with a nanocomposite membrane (polyacrylonitrile [PAN]/carbon nanotube [CNT]/copper oxide nanoparticle [CuO]) was prepared to provide thermoelectric conversion. The performance of the TE composite structure was evaluated by analyzing the mechanical properties, thermoelectric properties, and the ability of the structure to power small electronic equipment. The results showed that the nanocomposite membrane was effective in improving the electrical properties, whereas the glass fabric could significantly suppress the thermal conductivity. The results suggest that the glass fabric covered with nanocomposite fibers containing nanofillers (15 wt% CNT &amp; 15 wt% CuO) has a high potential to enhance the resistance against external force by 56% on average, compared to the uncovered glass fabric. Besides the power factor of the TE composite structure can reach up to 19.61 μW m<jats:sup>−1</jats:sup> K<jats:sup>−2</jats:sup>, which can power an output voltage of 3.2 V at a temperature difference from 20 to 80°C.</jats:p>
