“…There is also other research about strain sensors on high temperature environment. The polypyrrole (PPy)/single-walled carbon nanotube (SWCNT)/polydopamine(PDA)/cotton composite fabric reach showed outstanding heating performance at 144.6 • C [121]. A polyimide (PI)/carbon nanotubes (CNT) composite aerogel with the merits of super elasticity, high porosity, robustness, and high-temperature resistance was successfully prepared, and can be stable even at 250 • C [113].…”

“…A kind of sensor could detect minor motion. The polypyrrole (PPy)/single-walled carbon nanotube (SWCNT)/polydopamine(PDA)/cotton composite was employed to capture subtle motions originating from the vocal cords during drinking, as depicted in Figure 9 [121]. Remarkably, a unique and repetitive ∆R/R 0 response profile was observed when the volunteer drank 100 mL of orange juice in four sips, highlighting the composite's potential to sense complex and delicate motions of the vocal muscles (Figure 9j).…”

“…In Shak Sadi's study, to verify the potentiality of the PPy/SWCNT/PDA/Cotton composite as a component of a wearable heating device, the sample was attached to the index finger position of a hand glove while both ends of the composite were connected to an external DC voltage source (2 V) (Figure 14a) [121]. Within 30 s of heating, there was a very uniformly distributed profile of the surface.…”

Flexible and wearable electronics have attracted significant attention for their potential applications in wearable human health monitoring, care systems, and various industrial sectors. The exploration of wearable strain sensors in diverse application scenarios is a global issue, shaping the future of our intelligent community. However, current state-of-the-art strain sensors still encounter challenges, such as susceptibility to interference under humid conditions and vulnerability to chemical and mechanical fragility. Carbon materials offer a promising solution due to their unique advantages, including excellent electrical conductivity, intrinsic and structural flexibility, lightweight nature, high chemical and thermal stability, ease of chemical functionalization, and potential for mass production. Carbon-based materials, such as carbon nanotubes, graphene, and nanodiamond, have been introduced as strain sensors with mechanical and chemical robustness, as well as water repellency functionality. This review reviewed the ability of carbon nanotubes-, graphene-, and nanodiamond-based strain sensors to withstand extreme conditions, their sensitivity, durability, response time, and diverse applications, including strain/pressure sensors, temperature/humidity sensors, and power devices. The discussion highlights the promising features and potential advantages offered by these carbon materials in strain sensing applications. Additionally, this review outlines the existing challenges in the field and identifies future opportunities for further advancement and innovation.

“…Although various types of carbon materials, such as carbon nanotubes (CNTs) or graphene nanosheets, have been continuously used in additive (i.e., binder and surfactant)‐free coating approaches based on the surface functionalization or their self‐bundling nature, their relatively low electrical properties compared to bulk metals often limit the suitability for applications in energy storage systems requiring high energy and power efficiency. [ 54–58 ] On the other hand, metal nanomaterials (i.e., metal NPs or NWs) generally require a sufficient amount of polymeric binders or ligands to form a stably and uniformly cross‐linked three‐dimensional (3D) network that can effectively confine the metal components. Therefore, these coating processes typically require additional posttreatments such as chemical or electrical sintering, thermal annealing, laser irradiation, and flash light welding to eliminate the insulating polymeric species and form a well‐connected conductive (metallic) network.…”

The development of highly conductive fibril‐type textile electrodes is crucial for the advancement of various smart wearable electronics including high‐performance energy storage devices. To achieve this goal, it is essential to convert insulating textiles into conductive counterparts while maintaining flexibility and porosity. Additionally, the incorporation of electrochemically active components into textile conductors enables tailor‐made textile energy electrodes for specific applications. Thus, textile conductors act not only as conductors but also as energy reservoirs for energy‐active components, providing a facile electron transfer network. However, textile conductors fabricated by most existing methods face challenges such as low conductivity, blockage, and brittleness. One approach to overcome these problems is to utilize interfacial interactions between individual components and textiles. Conductive nanoparticle assembly and electrodeposition based on such rational design result in highly conductive, flexible, and large surface area textile conductors. The subsequent guided assembly of active components creates high‐performance textile energy electrodes. This perspective describes how interfacial interaction‐based assembly can enhance the performance of textile conductors and textile energy electrodes. It also explores various conductor preparation approaches and recent advances in the field for applications in supercapacitors and lithium‐ion batteries.

“…The mechanism of fiber-based resistive sensors refers to the conversion of mechanical signals applied to the human skin to changes in electrical resistance, and they can be divided into resistive strain sensors [41,42] and resistive pressure sensors [19,20]. Currently, fiber-based resistive strain sensors have been intensively studied [25,43,44]. For example, by coating graphene oxidized (GO) onto the calotropis gigantea yarn via the pad-dyeing method (Figure 2a) and then interweaving it with polyurethane yarn through a weaving process, a highly breathable and sensitivitytunable graphene-modified fabric (GMF) strain sensor was fabricated [45].…”

With the continuous growth of the global economy, an increasing concern has emerged among individuals with regard to personal digital health. Smart fiber-based sensors meet people’s demands for wearable devices with the advantages of excellent skin-friendliness and breathability, enabling efficient and prompt monitoring of personal digital health signals in daily life. Furthermore, by integrating machine learning and big data analysis techniques, a closed-loop system can be established for personal digital health, covering data collection, data analysis, as well as medical diagnosis and treatment. Herein, we provide a review of the recent research progress on fiber-based wearable sensors for personal digital health. Firstly, a brief introduction is provided to demonstrate the importance of fiber-based wearable sensors in personal digital health. Then, the monitoring of biophysical signals through fiber-based sensors is described, and they are classified based on different sensing principles in biophysical signal monitoring (resistive, capacitive, piezoelectric, triboelectric, magnetoelastic, and thermoelectric). After that, the fiber-based biochemical signal sensors are described through the classification of monitoring targets (biofluids and respiratory gases). Finally, a summary is presented on the application prospects and the prevailing challenges of fiber-based sensors, aiming to implement their future role in constructing personal digital health networks.
