The programmable nature of smart textiles makes them an indispensable part of an emerging new technology field. Smart textile‐integrated microelectronic systems (STIMES), which combine microelectronics and technology such as artificial intelligence and augmented or virtual reality, have been intensively explored. A vast range of research activities have been reported. Many promising applications in healthcare, the internet of things (IoT), smart city management, robotics, etc., have been demonstrated around the world. A timely overview and comprehensive review of progress of this field in the last five years are provided. Several main aspects are covered: functional materials, major fabrication processes of smart textile components, functional devices, system architectures and heterogeneous integration, wearable applications in human and nonhuman‐related areas, and the safety and security of STIMES. The major types of textile‐integrated nonconventional functional devices are discussed in detail: sensors, actuators, displays, antennas, energy harvesters and their hybrids, batteries and supercapacitors, circuit boards, and memory devices.

“…Meanwhile, two prominent peaks at 1570 cm −1 and 1320 cm −1 appear in the Raman spectrum of RC 5 which correspond to the G and D bands of MWCNTs, respectively. The G band is caused by inplane vibration of the C-C bonds, and D band is assigned to the disorder induced by defects and curvature in the nanotube lattice [22]. The G and D peaks further confirmed the presence of MWCNTs in the RC 5 composite films.…”

Regenerated cellulose (RC)-based composites reinforced with multi-walled carbon nanotubes (MWCNTs) were prepared by a facile casting method. The morphology and microstructure of the fabricated composites were characterized using transmission electron microscopy, Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. Thermogravimetry and derivative thermogravimetric analysis were conducted to investigate the effect of MWCNTs on the thermal behaviors of the RC. The results showed that the introduction of MWCNTs enhanced the thermal stability of the RC. Moreover, the effect of the dispersion state of MWCNTs in microcrystalline cellulose/ZnCl2 solutions with varying MWCNT loadings was studied by rheological tests. The mechanical properties of composite films were remarkably improved compared to those of pure RC film. Specifically, the composite film containing 3 wt% of MWCNTs exhibits a 123% enhancement in tensile strength and a 163% enhancement in the Young's modulus compared with the pure RC film.

“…Tai et al [195] utilized SWNTs and cotton threads to fabricate pressure sensors, which could accurately measure the value and location of pressure due to the graded thicknesses of SWNTs. Besides, Qi et al [196] used cellulose fibers coated with CNTs for sensing moisture. Due to the swelling of cellulose fibers induced by moisture, conductive CNT networks on the surface of the cellulose fibers would disconnect, enabling the capability to sense moisture with high sensitivity and fast response.…”

Flexible and wearable sensors have drawn extensive concern due to their wide potential applications in wearable electronics and intelligent robots. Flexible sensors with high sensitivity, good flexibility, and excellent stability are highly desirable for monitoring human biomedical signals, movements and the environment. The active materials and the device structures are the keys to achieve high performance. Carbon nanomaterials, including carbon nanotubes (CNTs), graphene, carbon black and carbon nanofibers, are one of the most commonly used active materials for the fabrication of high-performance flexible sensors due to their superior properties. Especially, CNTs and graphene can be assembled into various multi-scaled macroscopic structures, including one dimensional fibers, two dimensional films and three dimensional architectures, endowing the facile design of flexible sensors for wide practical applications. In addition, the hybrid structured carbon materials derived from natural bio-materials also showed a bright prospect for applications in flexible sensors. This review provides a comprehensive presentation of flexible and wearable sensors based on the above various carbon materials. Following a brief introduction of flexible sensors and carbon materials, the fundamentals of typical flexible sensors, such as strain sensors, pressure sensors, temperature sensors and humidity sensors, are presented. Then, the latest progress of flexible sensors based on carbon materials, including the fabrication processes, performance and applications, are summarized. Finally, the remaining major challenges of carbon-based flexible electronics are discussed and the future research directions are proposed. [56,57], have been used as the active components for the fabrication of flexible sensors. Among these materials, metal NPs can be used to fabricate flexible sensors with high sensitivity, but the sensing range and stretchability of these sensors are limited [58]. Besides, due to the limited chemical stability and reproducibility of metal nanowires, it is challenging to fabricate stable sensors using metal nanowires [10]. Similarly, conductive polymers with poor stability and conductivity are also difficult to be used for the fabrication of high-performance sensors [59]. In contrast, carbon materials are one of the most commonly investigated materials, especially CNTs and graphene (including graphene oxide (GO) and reduced graphene oxide (rGO)), due to their remarkable mechanical, electrical and thermal properties. To implement macroscopic applications, CNTs and graphene with superior properties in microscopic level should be converted into macroscopic functional assemblies, such as one dimensional (1D) fibers or yarns [60,61], two dimensional (2D) films or sheets [62,63], three dimensional (3D) architectures [64][65][66] (Fig. 1). The multi-scaled macroscopic carbon nanomaterials endow the flexible sensors with high sensitivity, excellent flexibility and good stability as well as desired configurations. Also, lo...
