“…100 More recently, electrochromic textile displays were achieved by screen-printing a pristine graphene ink on polyurethane coated cotton, with a second thermochromic polyurethane layer screen printed to the back of the conductive fabric. 12 Applying a bias of 12 V to the conductive fabric raised the temperature to 43°C, causing a reversible color change of the thermochromic pattern defined on the fabric surface (Figure 5d).…”

To realize the full gamut of functions that are envisaged for electronic textiles (e-textiles) a range of semiconducting, conducting and electrochemically active materials are needed. This article will discuss how metals, conducting polymers, carbon nanotubes, and two-dimensional (2D) materials, including graphene and MXenes, can be used in concert to create e-textile materials, from fibers and yarns to patterned fabrics. Many of the most promising architectures utilize several classes of materials (e.g., elastic fibers composed of a conducting material and a stretchable polymer, or textile devices constructed with conducting polymers or 2D materials and metal electrodes). While an increasing number of materials and devices display a promising degree of wash and wear resistance, sustainability aspects of e-textiles will require greater attention. Graphical abstract

“…Compared to traditional rigid heaters, flexible heaters can produce moderate deformation, such as bending, twisting, etc. [52][53][54][55] As a result, they have gained a lot of attention these years. And flexible substrates such as polyethylene terephthalate (PET), polyimide (PI) are generally used as supporting layers for the rigid heating elements.…”

“…The porous aerogel will achieve 55, 100, and 173 °C at an operating voltage of 2, 3, and 4 V, respectively. Moreover, the operating voltage range of heaters generally between 0 and 50 [42,48,52,70] However, high operating voltage brings higher device fabrication requirements. On the other hand, the high operating voltage is not feasible for wearable devices, and it is not energy friendly to use higher power resources.…”

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...

[5][6][7] Long-lasting phosphorescence is an attractive phenomenon for products that have the ability to glow in darkness. They function by the absorption of light into the crystal constituent of the phosphorescence compound.…”
