Optimization Design and Performance Study of Wearable Thermoelectric Device Using Phase Change Material as Heat Sink.

Wearable thermoelectric generators have great potential to provide power for smart electronic wearable devices and miniature sensors by harnessing the temperature difference between the human body and the environment. However, the Thomson effect, the Joule effect, and heat conduction can cause a decrease in the temperature difference across the thermoelectric generator during operation. In this paper, phase change materials (PCMs) were employed as the heat sink for the thermoelectric generator, and the COMSOL software 6.

Innovative Design of Bismuth-Telluride-Based Thermoelectric Transistors.

Conventional thermoelectric generators, predominantly based on the π-type structure, are severely limited in their applications due to the relatively low conversion efficiency. In response to the challenge, in this work, a BiTe-based thermoelectric transistor driven by laser illumination is demonstrated. Under laser illumination, a temperature difference of 46.

Study on Enhancing the Thermoelectric Stability of the β-CuSe Phase by Mn Doping.

CuSe is a promising thermoelectric (TE) material due to its low cost, Earth abundance, and high thermoelectric properties. However, the biggest problem of CuSe is its unstable chemical properties. In particular, under the action of an electric field or gradient temperature field, the chemical potential of copper ions inside the material increases.

Enabling High Quality Factor and Enhanced Thermoelectric Performance in BiBr-Doped SnMnTe via Band Convergence and Band Sharpening.

Lead-free SnTe-based materials are expected to replace PbTe and have gained much attention from the thermoelectric community. In this work, a maximum of ∼1.31 at 873 K is attained in SnTe via promoting a high quality factor resulting from Mn alloying and BiBr doping.
