Extreme climates have become frequent nowadays, causing increased heat stress in human daily life. Personal thermal management (PTM), a technology that controls the body's microenvironment, has promising strategy to address stress. While effective ordinary environments, traditional high-performance fibers, such as ultrafine, porous, highly thermally conductive, and phase change materials, fall short when dealing with harsh conditions or large temperature fluctuations. Aerogels, third-generation superinsulation material, garnered extensive attention among researchers for their applications building energy conservation, transportation, aerospace, attributed extremely low densities conductivity. aerogels historically faced challenges related weak mechanical strength limited secondary processing capacity, recent advancements witnessed notable progress development of wearable PTM. This underscores potential within serving self-powered smart devices sensors. Review offers timely overview PTM particular focus on wearability suitability. Finally, discussion classifies five types based aerogel function: insulation, heating, cooling, adaptive regulation (involving cooling), utilization devices.

Abstract The low thermal conductivity, poor toughness, and non‐reprocessability of thermosetting epoxy resins severely restrict their applications sustainable development in flexible electronics. Herein, liquid crystalline (LCE) dynamic ester disulfide bonds are introduced into the cured network bisphenol A resin (E‐51) to construct highly thermally conductive (LCER) vitrimers. LCER vitrimers demonstrate adjustable mechanical properties by varying ratio LCE E‐51, allowing it transition from soft strong. Typically, a 75 mol% 25 E‐51 results an in‐plane conductivity ( λ ) 1.27 W m −1 K , over double that pure vitrimer (0.61 ). tensile strength toughness increase 2.88 folds 14.1 MPa 2.45 20.1 MJ −3 respectively. Besides, phase covalent enable triple shape memory three‐dimensional reconstruction. After four reprocessing cycles, remain at 94% 72%, Integrating carbon nanotubes (CNTs) imparts photo‐thermal effect enables “on” “off” switch under near‐infrared light vitrimer. Furthermore, CNTs/LCER displays light‐induced actuation, self‐repairing, self‐welding besides closed‐loop recycling rapid degradation performance.
