Harnessing energy via cosmic cold and human heat with wearable nanofiber structures

Jiang and co-workers report in this issue of Device the development of a wearable passive daytime radiative cooling (PDRC) film integrated with a thermoelectric generator (TEG). This device converts body heat into electricity, while improving personal thermal comfort. The scalability is enabled by solution-blow-spinning and a straightforward laminating, supporting practical production for applications in personal devices and waste heat recovery.
