Review on Thermoelectric Aerogels and their Preparation Methods and Innovative Applications
Abstract
Thermoelectric aerogel is a novel type of material that can achieve the interactive transformation between electrical energy and thermal energy. Due to its unique characteristics such as low density, low thermal conductivity, high elasticity, and excellent thermoelectric properties, now it has received extensive attention in different fields such as high-temperature energy harvesting, intelligent sensing, and self-powered systems. This paper reviews the working principle and latest research progress of thermoelectric aerogels, including structural design innovation, performance optimization, and expansion of application fields. It focuses on exploring the application potential of thermoelectric aerogels in wearable devices, high-temperature monitoring and early warning, energy harvesting and conversion, and looks forward to its future development directions.
