ABSTRACT:The present work highlights the progress in the field of flexible thermoelectric generator (f-TEGs) fabricated by 3-D printing strategy on the typing paper substrate. In this study, printable thermoelectric paste was developed. The dimension of each planer thermoelectric element is 30mm*4mm with a thickness of 50 μm for P-type Bismuth Tellurium (Bi2Te3)-based/ poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) leg. A single thermoleg with this dimension can generate a voltage of 5.38 mV at a temperature difference of 70 K. The calculated Seebeck Coefficient of a single thermoleg is 76.86 μV/K. This work demonstrates that low-cost printing technology is promising for the fabrication of f-TEGs.

Key Techniques

This paper describes the process of fabricating micro thermoelectric generators (μ-TEGs) based on antimony telluride (Sb-Te) and bismuth telluride (Bi-Te). These materials have excellent thermoelectric (TE) conversion properties. The deposition and patterning processes for thermoelectric films are key techniques in the fabrication of μ-TEGs. However, it is difficult to form TE micropatterns using conventional semiconductor technologies because Sb-Te and Bi-Te are brittle and difficult to etch. Therefore, a semiconductor fabrication process is developed for TE film patterning. Here, various processes for depositing Sb-Te and Bi-Te TE films are described. Then, the combinations of the deposition and patterning techniques are reviewed. Finally, the generation properties of the μ-TEGs are summarized.

Abstract The thermoelectric performance of the segmented annular thermoelectric generators with the bismuth telluride and skutterudites has been investigated. The effect of the length ratio of the hot-segment leg to total length leg on the thermoelectric performance of the segmented annular thermoelectric generators is analysed and discussed and the optimization design of the annular thermoelectric generator with bismuth telluride and skutterudites as the materials with high thermoelectric performance is obtained. The result of the thermoelectric performance with the manipulated variable of the increase of length ratio, the output power, output voltage and efficiency of the segmented annular thermoelectric generators increase at the beginning then decrease afterwards. Additionally, to compare with the single bismuth telluride and skutterudites annular thermoelectric generators, the output voltage, output power and the conversion efficiency of the segmented annular thermoelectric generators can be improved twice. Lastly, the thermoelectric performance of the segmented annular thermoelectric generators operating in the changes of the temperature. The result has proved that as the temperature increase, the thermoelectric performance of the annular thermoelectric generator will also increase. Hence, the acquired results may be given some useful applications of the bismuth telluride and skutterudites on the segmented annular thermoelectric generators for waste heat recovery.

AbstractHarvesting body heat using thermoelectricity provides a promising path to realizing self-powered, wearable electronics that can achieve continuous, long-term, uninterrupted health monitoring. This paper reports a flexible thermoelectric generator (TEG) that provides efficient conversion of body heat to electrical energy. The device relies on a low thermal conductivity aerogel–silicone composite that secures and thermally isolates the individual semiconductor elements that are connected in series using stretchable eutectic gallium-indium (EGaIn) liquid metal interconnects. The composite consists of aerogel particulates mixed into polydimethylsiloxane (PDMS) providing as much as 50% reduction in the thermal conductivity of the silicone elastomer. Worn on the wrist, the flexible TEGs present output power density figures approaching 35 μWcm−2 at an air velocity of 1.2 ms−1, equivalent to walking speed. The results suggest that these flexible TEGs can serve as the main energy source for low-power wearable electronics.
