High-Performance Stretchable Thermoelectric Generator for Self-Powered Wearable Electronics.

Wearable thermoelectric generators (TEGs), which can convert human body heat to electricity, provide a promising solution for self-powered wearable electronics. However, their power densities still need to be improved aiming at broad practical applications. Here, a stretchable TEG that achieves comfortable wearability and outstanding output performance simultaneously is reported.

High-Power-Density Wearable Thermoelectric Generators for Human Body Heat Harvesting.

Wearable thermoelectrics has attracted significant interest in recent years. Among them, rigid-structure thermoelectric generators (TEGs) were seldomly employed for wearable applications, although those exhibit significant advantages of high device output performance and impact resistance. Here, we report a type of rigid wearable TEGs (w-TEGs) without ceramic substrates made using a simple cutting-and-bonding method.

Poly(3,4-ethylenedioxythiophene)/Te/Single-Walled Carbon Nanotube Composites with High Thermoelectric Performance Promoted by Electropolymerization.

Electrochemical polymerization has proven very effective in fabricating flexible organic/inorganic composite films with high thermoelectric (TE) performance. In this work, dynamic three-phase interfacial electropolymerization of 3,4-ethylenedioxythiophene (EDOT) combined with physical mixing of single-walled carbon nanotubes (SWCNT) and tellurium nanowires was employed to prepare PEDOT/Te/SWCNT thermoelectric composites. When the loadings of Te and SWCNT were changed, the electropolymerized PEDOT exhibited great capability of improving TE properties of the resultant composites with a highest electrical conductivity (σ) of 900.
