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.

Radiative cooling is the process by which an object on Earth's surface loses heat emitting thermal radiation into space through atmospheric window. Because continuous in time, radiative may cause overcooling winter or at night. Therefore, it essential to develop dynamic (DRC) approaches as opposed "static" cooling. In this work, we classify DRC passive and active according different sources of external response. By reviewing dual-band co-modulation mechanisms application fields with potential, provide a comprehensive analysis principles, structures, optical modulation, performance, energy-saving potentials modulation mechanisms. It should be noted that combining high-performance low-cost cooling/solar absorbing materials mechanical devices most readily available promising approach for applications. Furthermore, improvements manufacturing are usually overlooked compared optimization properties.

A wearable thermoelectric cooler (w-TEC) shows promising prospects in personal thermal management due to its zero emission, high efficiency, lightweight, and long-term stability. The flexible heatsinks are able promote the cooling effect of coolers, but capacity current coolers still has much room for improvement because relatively large resistance between heatsink. In this work, two-layer heatsink units composed hydrogel nickel foam fabricated attached a via silica gel. Thanks conductivity tight bond foam, effective heat conduction from body was achieved. addition, discrete endow w-TEC with excellent flexibility. bending radius is as small 7.5 mm, temperature reduction ∼10 °C can be realized at an input 0.3 flat or bent w-TEC. on-body testing, stable 7 obtained using AA battery voltage 1.5 V.

Flexible thermoelectric (TE) devices offer great potential for wearable thermal management and self-powered systems, but heat dissipation electrical interconnection remain key challenges. In this study, we address these issues by integrating flexible TE with phase-change material (PCM) heatsinks stretchable semi-liquid metal (semi-LM) interconnectors. The effectiveness of PCMs varying melting points temperature regulation in different environmental conditions is demonstrated, delivering cooling effects exceeding 10 °C. Furthermore, the utilization semi-LMs instead LMs enables excellent stretchability efficient dissipation. Moreover, generate power a density 7.3 μW/cm2 at an ambient 22 °C, making it ideal source sensing system. Successful integration into garments armbands confirms practicality adaptability devices, establishing them as critical components future wearables superior resilience to daily wear tear.
