“…Besides harvesting waste heat from factories, heat from photovoltaic cells [4] and high-power light-emitting diodes [5] have also shown potential for energy conversion through TE devices. On a smaller scale, a small temperature difference between the human body heat (waste heat energy) and the environment is also able to generate usable energy to power wearable electronic devices [6][7][8][9][10][11][12] .…”

The vast amount of waste heat released into the environment, from body heat to factories and boilers, can be exploited for electricity generation. Thermoelectrics is a sustainable clean energy solution that converts a heat flux directly into electrical power and vice versa and therefore has the potential for both energy harvesting and cooling technologies. However, the usage of thermoelectrics for large-scale applications is restrained by its device topologies and energy conversion cost efficiency trade-offs. The increase in complex topological designs reported in literature shows a shift towards customizability and improvement of thermoelectric devices for maximum energy conversion efficiency. Increasing design complexity will require an innovative, cost-effective fabrication method with design freedom capabilities. In light of this, this review paper seeks to summarize various thermoelectric topological designs as well as how 3D Printing technology can be a solution to the fabrication of cost-and performance-efficient thermoelectric devices. Specifically, as a process category of 3D Printing technology, Materials Jetting will be elaborated for its usefulness in the fabrication of thermoelectric devices. With in-depth research in materials jetting of thermoelectrics, the gap between small-scale materials research and scaled-up industry applications for energy harvesting through thermoelectric devices is expected to be bridged.

“…TEGs were chosen owing to their technological importance, and their robustness against wear and tear. [22][23][24] They can be used to harvest electrical energy from environmental waste heat. Vice versa, thermoelectrics (TEs) can also be used to convert electricity into heat pumps, serving as solid state refrigeration.…”

“…TE conversion efficiency is reliant on TE performance, which is usually assessed by a dimensionless parameter known as the TE figure of merit (ZT = σS 2 T/κ, where σ, S, κ and T are the electrical conductivity, Seebeck coefficient, thermal conductivity and absolute temperature, respectively). Furthermore, the power factor (PF = S 2 σ) is also adopted to evaluate the TE performance of polymers and polymer composites due to their low or similar thermal conductivity [8] .…”

Significant progress has been achieved for flexible polymer thermoelectric (TE) composites in the recent decade due to their potential application in wearable devices and sensors. In sharp contrast with the booming TE studies at room temperature, the TE performances of polymer TE composites received relatively less attention despite the significance for the application of TE composites in the high temperature environments. The TE and mechanical performances of flexible poly (3,4 ethylenedioxythiophene):poly(styrene sulfonate)/single-walled carbon nanotube (PEDOT:PSS/SWCNT) composite films with ionic liquid (IL) (refer to as “PEDOT:PSS/SWCNT-IL”) at high temperatures are studied in the present work. The resultant composite film shows the increasing TE performances with increasing temperatures and SWCNT contents. The maximum value of the power factor reaches 301.35 W m-1 K-2 at 470 K for the PEDOT:PSS/SWCNT-IL composite. Besides, the addition of IL can improve the elongation at break of composites compared to the IL-free composites. This work promotes the advance of flexible polymer TE composites and widens the potential applications at different temperature ranges.
