“…In addition to sensing materials, a flexible electrode is an important part of the system that plays an equally significant role in enhancing the sensitivity and working pressure range of the sensor, which was already demonstrated in our previous study [26]. In our investigation, the flexible electrode (nickel fabrics) was manufactured in accordance with a novel "subtracting and transferring" protocol, with designed patterns on a polyimide (PI) or polyethylene terephthalate PET film (thickness = 100 µm), which served as the working electrode similar to our previous sensor embodiment [26] (Fig. 2i and Figs S11, S12).…”

“…Yu et al [94] prepared an ultrathin all-fabric capacitive sensor with two AgNWs electrodes and a breathable micropatterned nanofiber dielectric layer sandwiched between them (Figure 4d). Due to the unique structure of the micropatterned nanofiber dielectric layer, the sensor shows a response time of 27.3 ms. Xu et al [95] prepared fabric sensors using laser engraved silver-plated fabric as electrodes and graphite flake modified nonwoven fabric as the sensing material. Due to the unique structure of the electrodes and the random rough surface of the sensing material, the sensor has a fast response time of Yu et al [94] prepared an ultrathin all-fabric capacitive sensor with two AgNWs electrodes and a breathable micropatterned nanofiber dielectric layer sandwiched between them (Figure 4d).…”

Innovations related to textiles-based sensors have drawn great interest due to their outstanding merits of flexibility, comfort, low cost, and wearability. Textile-based sensors are often tied to certain parts of the human body to collect mechanical, physical, and chemical stimuli to identify and record human health and exercise. Until now, much research and review work has been carried out to summarize and promote the development of textile-based sensors. As a feature, we focus on textile-based mechanical sensors (TMSs), especially on their advantages and the way they achieve performance optimizations in this review. We first adopt a novel approach to introduce different kinds of TMSs by combining sensing mechanisms, textile structure, and novel fabricating strategies for implementing TMSs and focusing on critical performance criteria such as sensitivity, response range, response time, and stability. Next, we summarize their great advantages over other flexible sensors, and their potential applications in health monitoring, motion recognition, and human-machine interaction. Finally, we present the challenges and prospects to provide meaningful guidelines and directions for future research. The TMSs play an important role in promoting the development of the emerging Internet of Things, which can make health monitoring and everyday objects connect more smartly, conveniently, and comfortably efficiently in a wearable way in the coming years.

“…The subtle construction of 3D structures provides a new train of thought and method to solve this problem. The reported research shows two types of microstructures for sensing materials: the first is prepared using the template method, wherein a plate with a special micro surface is used as a template, and a highly conductive thin layer is arranged onto the complex surface of a polymer to form a pyramid structure [ 17 ] and microscale polymeric forests, [ 18 ] indentation, [ 19 ] leaf impression, [ 20 ] fingerprint‐structured channel, [ 21 ] and micro column structure. [ 22 ] An interlocking contact is formed under pressure to increase the effective surface contact area.…”

Wearable intelligent sensor materials have broad application prospects for human health detection and robot kinematics. 3D structure sensors have the advantages of high sensitivity, a wide detection range, and high strength, as is widely reported in existing research. Here, a sandwich structure involving an encapsulation layer, a 3D conductive network, and an encapsulation layer is prepared. Polyaniline acts as an active conductive filler for the 3D conductive network, while silk fibroin and poly (lactic‐co‐glycolic acid) are used to form a network for carrying conductive materials. Additionally, K‐carrageenan is added to encapsulate the 3D conductive network and prepare a high‐performance green skin sensor. The sensor exhibits high sensitivity (2.54 kPa−1) and a wide linear detection range (165.3 kPa). In addition, the pressure sensor possesses excellent durability (>2000 cycles) and a fast response time of 160 ms. Moreover, the sensor is compatible and biodegradable and encapsulated by a nontoxic water‐soluble polymer. On this basis, skin sensors for health monitoring systems and intelligent interactive systems are reported, thus enabling future applications in medical detection and human–machine interaction.
