With the emergence and development of smart wearable electronics and healthcare systems, strong demands for energy saving and effective personal thermoregulation have attracted great attentions. In order to prevent thermal runaway and realize human thermal comfort during the long‐term wear of electronics that closely contact to skin, personal thermal management is emerging as an important strategy to regulate and balance the heat exchange between human body and surrounding environments. Smart fibers and textiles with light weight, mechanical flexibility, multiple responsive, as well as, excellent thermoregulation ability for efficient personal thermal management are eagerly desired in the healthcare applications of wearable electronics. This review summarizes the state‐of‐the‐art advancements on emerging smart fibers and textiles for personal thermal management, including personal cooling, warming, and thermostatic according to the specific healthcare application fields and individual requirements. Advanced fibers and textiles could provide adjustable smart personal thermal regulation ability, in response to various external stimuli and the changes of surrounding environments for efficient personal healthcare are focused on. Finally, the opportunities and challenges of smart fibers/textiles for personal thermal management are also discussed.

Metal–organic frameworks (MOFs) have been recognized vastly as stimuli‐responsive materials owing to their extreme sensitivity toward the stimuli that make them flawless nominees for multifunctional device applications. However, MOFs are often oversensitive toward moisture, which significantly affects their stable responses and reproducibility. Herein, a MOF–polymer display (i.e., copper‐based MOF with polydimethylsiloxane) is developed that exhibits high sensitivity toward temperature changes without getting affected by moisture. In response to the thermal gradient, the display exhibits the change in color from sky blue to dark blue when the temperature varies from 30 to 100 ºC, which is attributed to the second‐order phase transition within the time interval 40 s and reversible in 60 s. To provide insights on the mechanism, ex situ UV–vis and temperature‐dependent operando X‐day diffraction are conducted, which unveils that the color change in the display is associated with reversible contraction/expansion of the unit cell parameters. In addition to that, the thermoresponse of the display remains unaffected under mechanical deformations, which indicates that the color display is mechanically and thermally stable. The as‐developed color display is mechanically robust and highly sensitive toward temperature change; it can be utilized as the color indicator in signaling temperature rise in smart mobiles or laptops during discharging to keep the user safe or applications in augmented intelligence.

“…Extensive studies have been conducted to prepare VO 2 thin films or nanopowders, such as the sol-gel method [13], vapor phase transport [14], pulsed-laser deposition [15] hydrothermal treatment [16], and magnetron-sputter [17]. By contrast, hydrothermal treatment has been considered the main method used to prepare VO 2 because it functions at both a high temperature and pressure that are well-suited to control the morphology, crystallinity, and chemical stoichiometry of the final product [18].…”

Vanadium dioxide (VO2) has attracted interest from researchers because it undergoes a metal–insulator phase transition (MIT), which is accompanied by a reversible and remarkable change in both electrical and optical properties. VO2 exhibits numerous polymorphs and thus it is essential to control the growth of specific monoclinic VO2 (M) and rutile VO2 (R) phases. In this study, we developed a cost-effective and facile method for preparing VO2 nanorods with a highly crystalline monoclinic phase by one-step hydrothermal synthesis, in which only V2O5 and H2C2O4 are used as raw materials. The phase evolution of VO2 during the hydrothermal process was studied. The obtained VO2 nanorods were thoroughly mixed with fluorocarbon resin and homogeneous emulsifier in an ethanol solution to obtain a VO2 dispersion. To prepare VO2 films, screen printing was performed with a stainless steel screen mesh mask on glasses or fabric substrate. The VO2 coating had good thermochromic performance; the infrared transmittance change was greater than 20% @1.5 μm whilst keeping the visible transmittance greater than 50%. Meanwhile, the polyester base coating on the fabric had an emissivity change of up to 22%, which provides a solution for adaptive IR camouflage.
