Molten drawing inorganic ductile Ag2S0.7Te0.3 fibers with high thermoelectric performance and stability

One potential application for flexible thermoelectric (TE) devices based on inorganic ductile fiber materials is the development of self-powered wearable electronics. In the work, the molten drawing method was employed for fabricating inorganic ductile Ag₂S_0.7Te_0.3 fibers. The output voltage and maximum output power of the single fiber are 3.3 mV and 837.4 nW, respectively, under a temperature difference of 50 K. The Ag₂S_0.7Te_0.3 fiber shows outstanding stability performance in the service stability test with a critical electric density of 36 A cm⁻² and exhibits a tensile strain of 5%. The high temperature sensitivity of the Ag₂S_0.7Te_0.3 fibers TE device demonstrates the application potential in wearable electronics products.
