“…7b). In general, the charge carrier generation and temperature response of PEDOT: PSS is better than the CNT [49,50]. Therefore, with increase in temperature, both the CNT and PEDOT: PSS contributes to the charge carrier generation and transportation through hopping and tunnelling mechanisms and result in huge drop in the resistance (two times higher than CNT).…”

“…Conductive fibers can also function as temperature sensors as they may show linear or nonlinear changes in electrical resistivity under varying temperatures. For example, PEDOT:PSS‐dyed cotton threads showed a negative temperature coefficient characteristics with 167.1 Ω °C −1 sensitivity and 99.8% linearity at the temperature range of −50 to 80 °C . They can be thus woven into the fabric to construct a temperature sensor array or network that can measure the spatial and temporal temperature gradients with high sensitivity and accuracy.…”

The existing fiber-shaped energy storage devices include the supercapacitor, [15] the lithium (Li)-ion battery, [16] the lithium-sulfur battery, [17] the lithium-air battery, [18] the zinc-air battery, [19] the aluminum-air battery, [20] the sodiumion battery, [21] the zinc-ion battery, [22] and the silver-zinc battery. [23] Among them, the supercapacitor has been reported mostly due to the easy fabrication, and lithium-ion battery has laid the foundation for the development of other fiber-shaped batteries, which are thus discussed mainly in this review. 3) Light-emitting devices have been developed for various applications such as display, illumination, and photo therapy. According to the working mechanisms, there are electroluminescence, [24] mechanoluminescence, [25] photoluminescence, [26] thermoluminescence, [27] sonoluminescence, [28] and chemiluminescence. [29] Among these, fiber-shaped electroluminescent devices have been developed extensively due to their good controllability, driven by direct current (DC) [30] or alternating current (AC) [31] electrical method, which are expounded mainly later. 4) Fibershaped sensors have found great potentials in the field of wearable medical devices for fitness monitoring and medical diagnostics especially as aging populations grow. By virtue of the 1D structure, fiber-shaped sensors can be implanted into the body with little injure or they can detect multiple signals simultaneously after integration into a tiny unit. [32] Fiber-shaped sensors generally work via physical processes on the basis of conducting fiber [33] and optical fiber, [34] and chemical processes based on chemical ligand. [35] Thereinto, fiber optic sensors have already been used in petrochemical, electric power, medical, civil engineering, etc. The detailed discussions about the above three fiber-shaped sensors are presented in the later section.Despite the great progress made in fiber and textile electronics, we have to realize that most of the research results are far from practical applications due to several existing obstacles. The performances of fiber-shaped electronic devices are not good enough to attract investors. For instance, although fiber-shaped solar cells have achieved a record power conversion efficiency (PCE) of 10%, [36] this value falls far below the certified efficiency of 24.2% for planar solar cells. [37] Besides, fiber-shaped electronic devices often decay in performance further as their lengths increase. Apart from low performances, scalable fabrication is another hard nut to crack if fiber-shaped electronic devices are to be commercialized. For one thing, researchers usually can only realize fiber-shaped electronic devices with the lengths from several to hundreds of millimeters at present owing to the absence of appropr...

Technology has become ubiquitous, it is all around us and is becoming part of us. Together with the rise of the Internet-of-Things (IoT) paradigm and enabling technologies (e.g., Augmented Reality (AR), Cyber-Physical Systems, Artificial Intelligence (AI), blockchain or edge computing), smart wearables and IoT-based garments can potentially have a lot of influence by harmonizing functionality and the delight created by fashion. Thus, smart clothes look for a balance among fashion, engineering, interaction, user experience, cybersecurity, design and science to reinvent technologies that can anticipate needs and desires. Nowadays, the rapid convergence of textile and electronics is enabling the seamless and massive integration of sensors into textiles and the development of conductive yarn. The potential of smart fabrics, which can communicate with smartphones to process biometric information such as heart rate, temperature, breathing, stress, movement, acceleration, or even hormone levels, promises a new era for retail. This article reviews the main requirements for developing smart IoT-enabled garments and shows smart clothing potential impact on business models in the medium-term. Specifically, a global IoT architecture is proposed, the main types and components of smart IoT wearables and garments are presented, their main requirements are analyzed and some of the most recent smart clothing applications are studied. In this way, this article reviews the past and present of smart garments in order to provide guidelines for the future developers of a network where garments will be connected like other IoT objects: the Internet-of-Smart-Clothing.
