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

Personal thermal management textiles have garnered a lot of attention because they can efficiently preserve the body's thermal and moisture comfort while saving energy consumption. Nonetheless, conduction cooling‐based textile research is scarce and frequently encounters obstacles like overlooking through‐plane heat conduction, moisture management, and durability assurance. Here, a dual‐cooling textile (DCT) that combines high‐efficiency heat dissipation and sweat evaporation with a 3D thermal conductive network and Janus wetting structure is demonstrated. The DCT achieves notable in‐plane and through‐plane thermal conductivity (8.57 and 0.70 W m−1 K−1), along with practical mechanical qualities (tensile fracture strength of 65 MPa), under the influence of the 3D multistage thermal conduction network. Additionally, the DCT benefits from its Janus wetting structure, exhibiting unidirectional moisture‐wicking capability (transport index of 1081%) and fast water evaporation performance (0.34 g h−1). Rapid heat dissipation and sweat evaporation are advantageous features for the cooling of the human body in both static and dynamic situations. Compared to cotton fabric, DCT can lower the temperature by up to 3.7 °C. This strategy provides a fresh perspective on the development of advanced functional textiles for personalized cooling and energy savings in buildings.

Flexible electronics are integral in numerous domains such as wearables, healthcare, physiological monitoring, human–machine interface, and environmental sensing, owing to their inherent flexibility, stretchability, lightweight construction, and low profile. These systems seamlessly conform to curvilinear surfaces, including skin, organs, plants, robots, and marine species, facilitating optimal contact. This capability enables flexible electronic systems to enhance or even supplant the utilization of cumbersome instrumentation across a broad range of monitoring and actuation tasks. Consequently, significant progress has been realized in the development of flexible electronic systems. This study begins by examining the key components of standalone flexible electronic systems–sensors, front‐end circuitry, data management, power management and actuators. The next section explores different integration strategies for flexible electronic systems as well as their recent advancements. Flexible hybrid electronics, which is currently the most widely used strategy, is first reviewed to assess their characteristics and applications. Subsequently, transformational electronics, which achieves compact and high‐density system integration by leveraging heterogeneous integration of bare‐die components, is highlighted as the next era of flexible electronic systems. Finally, the study concludes by suggesting future research directions and outlining critical considerations and challenges for developing and miniaturizing fully integrated standalone flexible electronic systems.
