“…Therefore, the change of one or more parameters of the permittivity, spacing, or effective area will cause a change in capacitance of the device, and then the magnitude of the mechanical stimulus that causes the parameter change can be quantified. Capacitive TMSs feature properties of high response repeatability, small signal drift, long term cycle stability, and low energy consumption, but they are susceptible to external field interference, relatively low sensitivity, and limited sensing range [44].

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.

“…Two flexible conductive fabrics are used as electrode plates, separated from flexible dielectric spacers (such as foams, fabric spacers and soft polymers). To date, Chen and co-workers 162 developed a topographical modification contributing to the conductivity and durability of the wearable capacitive sensors. The device realized simultaneous detection of the change of distance and angle, therefore recording dynamic information in real-time such as speaking, blinking, head movement and joint movement, etc.…”

“…[ 8,9 ] Among the many studies, flexible pressure sensors for monitoring the motion signal parameters of the human body are undoubtedly the most representative. [ 10,11 ] In general, pressure sensors can be divided into four types on the basis of sensing mechanisms: piezocapacitance, [ 12 ] triboelectricity, [ 13,14 ] piezoresistivity, and piezoelectricity. [ 15,16 ] Piezoresistive pressure sensors have been widely studied and applied owing to their simple structure, high accuracy, and excellent durability.…”

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.
