Abstract

Highlights

Muscle-inspired anisotropic aramid nanofibers thermoelectric aerogel was prepared via directional freeze-drying strategy.
Resultant anisotropic aerogel exhibited high-efficiency thermoelectric conversion with Seebeck coefficient of 46.78 μV K⁻¹ and low thermal conductivity of 0.048 W m⁻¹ K⁻¹.
Thermoelectric aerogel-based multistage wireless high-temperature alarm system achieves a wide temperature sensing range (50–400 °C) and sensitivity response time (trigger time ~ 1.43 s) for firefighting clothing.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
