In recent years, with the development of the Internet of Things (IoT) and wearable technology, the research and exploration of thermoelectric materials have been greatly promoted. However, traditional thermoelectric materials are rigid and brittle. Thermoelectric devices made of these materials usually cannot be closely attached to the heat and cold sources that provide temperature differences, thus limiting the application of thermoelectric materials. Therefore, manufacturing new high-performance flexible thermoelectric devices is still a huge challenge. In this work, polyimide/copper (PI/Cu) substrate was deposited by electron deposition technology. The flexible thermoelectric thin film device was fabricated by bonding [Formula: see text]-type and [Formula: see text]-type bismuth telluride (Bi2Te[Formula: see text] slurries onto the PI/Cu substrate. Then, the PDMS film was coated on the device to make the device waterproof and oxidation resistant. The output voltage and maximum power of this device, at the temperature of 80 K, reach 97.5 mV and 60 uW, respectively. After 200 cycles of cyclic bending experiments, 90% high conductivity retention can be maintained. It demonstrates that the new flexible thermoelectric thin film has good flexibility and excellent stability. This work provides a simple method for the preparation of flexible thermoelectric thin films and opens up a new way for its application in the sensing equipment and wearable device of the IoT.

Sustainable development is the way to ensure the Human progress within the bounds of the ecological possible. In this context thermoelectric systems can play an important role. However, the price of most high-performance thermoelectric devices is high, mainly due to the use of expensive elements, which raised the interest for cheap thermoelectric materials. It is also clear that the production of competitive thermoelectric devices critically depends on other factors, like the manufacturing costs, and that the materials fabrication simplicity, reproducibility, and use of easy scale-up processes will also play a fundamental role.Tetrahedrites, with generic formula Cu10M2Sb4S13 (M = Cu, Mn, Fe, Co, Ni, Zn), are world spread sulfosalt minerals that crystallize in the cubic Cu12Sb4S13-type structure. They are environment friendly materials mainly formed by non-expensive elements. Recently, mineral based and synthetic tetrahedrites were considered as promising thermoelectric materials, with zT ~ 1 at T ~ 700 K. Though, tetrahedrite melts incongruently, the preparation of appropriate tetrahedrite samples usually requiring long-term annealing procedures. Here we present a set of systematic studies on the use of tetrahedrites as low-cost and sustainable thermoelectric materials. The raw material prices evaluation, the feasibility of rapid, scalable, cheap tetrahedrite preparation and their long term stability and resistance to oxidation under working conditions are highlighted.

Thermoelectric devices have recently attracted considerable interest owing to their unique ability of converting heat to electrical energy in an environmentally efficient manner. These devices are promising as alternative power generators for harvesting electrical energy compared to conventional batteries. Inorganic crystalline semiconductors have dominated the thermoelectric material fields; however, their application has been restricted by their intrinsic high toxicity, fragility, and high cost. In contrast, organic thermoelectric materials with low cost, low thermal conductivity, easy processing, and good flexibility are more suitable for fabricating thermoelectric devices. In this review, we briefly introduce the parameters affecting the thermoelectric performance and summarize the most recently developed carbon-material-based organic thermoelectric composites along with their preparation technologies, thermoelectric performance, and future applications. In addition, the p- and n-type carbon nanotube conversion and existing challenges are discussed. This review can help researchers in elucidating the recent studies on carbon-based organic thermoelectric materials, thus inspiring them to develop more efficient thermoelectric devices.
