Nanoarchitectonics of High-Performance and Flexible n-Type Organic-Inorganic Composite Thermoelectric Fibers for Wearable Electronics.

Since most conductive polymers are -type, developing high-performance -type organic-inorganic composite thermoelectric (TE) fibers is a great challenge. Herein, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)-coated AgTe nanowires (PC-AgTe NWs) were prepared by a liquid-phase reaction using PEDOT:PSS-coated Te nanowires (PC-Te NWs) as templates, and the PEDOT:PSS/PC-AgTe NWs composite fibers were then prepared by wet spinning. As the content of PC-AgTe NWs increases, the composite fiber changes from -type to -type.

A Highly Robust, Multifunctional, and Breathable Bicomponent Fibers Thermoelectric Fabric for Dual-Mode Sensing.

Wearable thermoelectric (TE) materials are seen as excellent candidates for flexible electronics because of their unique self-powered properties, multistimulus sensing and human waste heat conversion. However, currently reported flexible TE materials still face challenges such as poor durability, uncomfortable wearing and sensing signals crosstalking each other. Herein, this study describes a hot-air cross-linking method for the preparation of multifunctional TE fabrics with enhanced durability.
