“…Flexible composite PCMs can be melt spun of polyamide 6 (PA6) into PCFs via a molecular chain structural selection strategy and nano-hybridization technique. The obtained PCFs could delay temperature rise for 591 s, suggesting a temperature buffering effect ( Figure 6 A) ( Xia et al., 2021 ). Here, fumed silica nanoparticles were used as the inorganic carriers to adsorb PCMs and the interaction between fumed silica nanoparticles formed a fluffy network, providing an enhanced physical adsorption capacity as well as high thermal conductivity.…”

Flexible/foldable, self-supporting, porous, and wearable bifunctional fabrics for sunlight heating and phase change temperature control are designed and constructed for wearable thermal management. In this study, coaxial fibers with polyvinylidene fluoride polymer solution uniformly doped with Cu7S4 as sheath and n-eicosane as core components are fabricated by electrospinning technology. Remarkably, based on the fast solar-to-thermal conversion of the photothermal conversion material, the as-obtained fabric provides sunlight heating for an extra warmth of 25 °C within 1.5 min. Besides, active temperature control via fabric internal phase transformation reduces the daily temperature fluctuations, which is superior to that of the normal and traditional cotton fiber. Impressively, the present bifunctional fabric possesses both better thermal comfortability, including breathability, sweat wicking, and stain resistance, and high durability against wash and soak over 120 h, suggesting its great potential in wearable technologies for thermal regulation.

The technological evolution presents us with infinite possibilities of deformable electronics, far beyond what is possible with conventional electronics. [9][10][11][12] For the past few years, heaters' development has grown rapidly due to wearable electronics' advances and the growing need for practical medical requirements. [13][14][15] The advantages of heaters, such as lightweight, good heating stability, and flexibility, make heaters generally a better choice than conventional heating elements. Various heaters applications have been reported, including deicing devices [16][17][18][19][20] , thermal management devices [21][22][23][24][25] , healthcare [26][27][28][29] , wearable sensors [30][31][32] , etc. For instance, heaters can provide the warmth required to extend the operating temperature of liquid crystal displays (LCDs) in cold environments or can increase the temperature for antifogging systems, anti-icing, deicing of optics, or optical displays [33,34] .Conventional rigid heaters are usually using semiconductor or metallic materials as the heating elements, which have demonstrated stable and excellent performance. For example, Rao and co-workers [35] fabricated a transparent heater by physically depositing Au on a quartz substrate and using an acrylic resin as a crack sacrificial template. It is a transparent conductor with a low sheet resistance of 5.4 Ω sq −1 and a high-temperature heater that can reach ≈600 °C within 38 s by applying a voltage of 15 V. However, the heater is restricted in many applications with portable needs, such as human motion detection, wearable electronics, etc., due to the rigid and thick quartz substrate.As shown in Figure 1a, conventional heaters always consist of a heating element and rigid substrate, and the working principle of electrical heaters is based on the Joule effect and thermal diffusion. However, inherently rigid substrate limits the applications of conventional heaters [36] . Flexible and stretchable heaters had gained tremendous attention with the advances of soft electronics. [37][38][39] Flexible heaters can adapt to moderate deformation, such as bending and twisting. [40,41] And stretchable heaters have more application scenarios due to their stretchable characteristics. [42,43] In the last few years, deformable heaters have gained rapid development due to their wide strain range, good repeatability and low density. [44] Figure 1b shows different structure designs of deformable heaters. One of the most significant advantages Conventional heaters have evolved from traditional rigid heaters to flexible heaters, stretchable heaters, and deformable heaters for the development of soft electronics. Film-based or filament-based heaters can be designed and engineered to fulfill the deformable, adaptable and stretchable applications. Compared with conventional heaters, deformable heaters can maintain stable electrothermal property even with large deformation. Based on this, deformable heaters have shown great potential to be used in the field of Internet of Thin...
