Large-area radiation-modulated thermoelectric fabrics for high-performance thermal management and electricity generation

Flexible thermoelectric systems capable of converting human body heat or solar heat into sustainable electricity are crucial for the development of self-powered wearable electronics. However, challenges persist in maintaining a stable temperature gradient and enabling scalable fabrication for their commercialization. Herein, we present a facile approach involving the screen printing of large-scale carbon nanotube (CNT)–based thermoelectric arrays on conventional textile. These arrays were integrated with the radiation-modulated thermoelectric fabrics of electrospun poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) membranes for the low-cost and high-performance wearable self-power application.…
