Abstract Fiber‐based thermoelectric (TE) device that can collect waste heat of human body and convert it into electricity is growing fast great significance for sustainable development. Although ionic (i‐TE) ionogels are considered to be the next generation TE materials, construct ionogel fiber with synergistically enhanced mechanical i‐TE performances remains big challenge. Herein, poly(vinylidene fluoride‐co‐hexafluoropropylene)/1‐ethyl‐3‐methylimidazolium dicyanamide/ethanol/NaTFSI/SiO 2 (PH/ED‐E‐Na‐SiO ) ultrahigh Seebeck coefficient 47.5 mV K −1 conductivity 43.7 mS cm constructed by a proposed antisolvent‐doping‐hybrid synergistic strategy. The mainly attributed low crystalline structure improvement in ions dissociation, migration, diffusion difference. corresponding power factor PH/ED‐E‐Na‐SiO film as high 9845.8 µW m −2 , which almost highest value ever reported. Based on this, comparable significantly tensile strength strain (from 327 KPa 47% 17.7 MPa 70% fiber) prepared simple coating process. It weaved wearable generates thermovoltage lights light‐emitting diode (LED) bulb, demonstrating its application potential energy supply device.

Mechanoluminescent (ML) materials emit light by trapping and releasing charge carriers under mechanical stress. However, previous studies do not fully reveal the relationship between emitting intensity stress, thereby affecting accuracy of stress measurement. This study addresses this gap systematically investigating ML cylinders with various sizes loading paths using theoretical analysis simulations, focusing on maximum contact equivalent distribution, strain energy density at point In combination experiments, behavior optical responses normal compressive forces that luminescence is closely related to cylinder size path, effectively reflecting distributions in objects different complex conditions. Particularly, within elastic range ideal conditions where lateral ignored, nearly equal The linearly intensity, while proportional square root intensity. work promotes application structural health monitoring visualization.

Since most conductive polymers are p-type, developing high-performance n-type organic–inorganic composite thermoelectric (TE) fibers is a great challenge. Herein, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)-coated Ag2Te nanowires (PC-Ag2Te NWs) were prepared by liquid-phase reaction using PEDOT:PSS-coated Te (PC-Te as templates, and the PEDOT:PSS/PC-Ag2Te NWs then wet spinning. As content of PC-Ag2Te increases, fiber changes from p-type to n-type. The PEDOT: PSS coating greatly improves dispersibility in matrix, resulting an ultrahigh 87.5 wt % fibers, which exhibited Seebeck coefficient −61.3 μV K–1 power factor 65.3 μW m–1 K–2. value higher than those previously reported TE fibers. Contrary estimated thermal conductivity other reports, this work, was measured via transient photoelectrothermal (TPET) technique. In addition, has good tensile properties mechanical strength, elongating at break 47.37% stress 6.59 MPa. For application demonstration, self-powered temperature sensor assembled, can utilize vertical difference between human body environment respond quickly small difference.
