“…74 For metallic materials, they are usually reported to exhibit not only capability for Joule heating but also supply good thermal radiation reflectance. 18,52,53,76 Combined with smart warming control systems, the active Joule-heating textiles can work as smarter integrated personal thermal management devices. Huang et al reported a novel sandwich-structural textile (Ag nanofibers/silk fabric/Pt nanofibers) in which Joule-heating elements and temperature sensors are incorporated.…”

To realize improved human body thermal comfort and reduce energy consumption on building heating and cooling, personal thermal management emphasizing energy management of human body and its local environment is emerging as a promising solution. Advanced textiles are being invented and developed to effectively regulate heat exchange between human body and its surroundings. Here, recent progress on advanced textiles for personal thermal management and its significance in energy efficiency are reviewed. We will mainly discuss textiles with engineered properties targeting at passively controlling human body heat dissipation routes, the active warming and/or cooling textiles, and the responsive textiles that offer adaptive personal thermal management ability according to the external stimuli. An outlook discussing important challenges and opportunities in this field is also presented.

“…Not only the personal cooling/ heating performance is targeted, other characteristics such as water vapor/air permeability, tensile force, wicking distance, www.advancedsciencenews.com density, opacity, thermal comfort zone are also tested in these studies to ensure similar wearability as cloth.

“…Basically, the wearability include breathability, washability, stretchability, and tailorability. [22,87,115,129] Breathability is defined as the air and water vapor permeability through the textiles, which is important for personal thermoregulation via thermal convection and vapor evaporation mainly. Washability is defined as the performance invariability of textiles after manual or mechanical washing including color, dimensional ability, touch, feel, and the appearance.…”

us warm in cold climates and shielded us from the nakedness for modesty and civilization. [1,2] Cloth is also a platform for artists, designers, and tailors to advance the clothing demands with emerging materials, process, and fashion. [2] While the majority of the functionalities of clothes lie in their physical attributes, such as their softness, breathability, air/ vapor permeability, and, of course the appearance, their role in thermal management is equally, if not more, important. The primary goal of clothing is to satisfy human being's basic needs in thermal comfort, by providing cooling in the hot environment or heating in the cold environment. [1] The energy management aspect of clothing is becoming an increasingly important and attractive aspect due to our increasing awareness to energy consumption and our persisting pursuit of comfort and health. The finite availability and the associated environmental consequence of fossil fuels have motivated us to save energy from virtually all aspects of our daily lives. A suitable thermal envelop is a necessity for our living and working. To create a comfortable indoor environment, the building heating, ventilation, and air conditioning (HVAC) systems are widely used for space cooling and heating at the expense of excessive energy consumption. [3][4][5][6] According to United States In this decade, the demands of energy saving and diverse personal thermoregulation requirements along with the emergence of wearable electronics and smart textiles give rise to the resurgence of personal thermal management (PTM) technologies. PTM, including personal cooling, heating, insulation, and thermoregulation, are far more flexible and extensive than the traditional air/liquid cooling garments for the human body. Concomitantly, many new advanced materials and strategies have emerged in this decade, promoting the thermoregulation performance and the wearing comfort of PTM simultaneously. In this review, an overview is presented of the state-ofthe-art and the prospects in this burgeoning field. The emerging materials and strategies of PTM are introduced, and classed by their thermal functions. The concept of infrared-transparent visible-opaque fabric (ITVOF) is first highlighted, as it triggers the work on advanced PTM by combining it with radiative cooling, and the corresponding implementations and realizations are subsequently introduced, followed by wearable heaters, flexible thermoelectric devices, and sweat-management Janus textiles. Finally, critical considerations on the challenges and opportunities of PTM are presented and future directions are identified, including thermally conductive polymers and fibers, physiological/psychological statistical analysis, and smart PTM strategies.
