“…20−22 Moreover, MXene is also popular in the research of pressure sensors because the large specific surface area of MXene effectively increases the binding force with the substrate, resulting in excellent mechanical properties. 23 Recently, Guo et al reported a fabric pressure sensor based on MXene coating. 24 The MXene-coated fabric was sandwiched between two polymer substrates decorated with forefinger electrodes.…”

Recently, wearable sensors and electronic skin systems have become prevalent, which can be employed to detect the movement status and physiological signals of wearers. Here, a pressure sensor composed of mesh-like micro-convex structure polydimethylsiloxane (PDMS), MXene nanosheet/Ag nanoflower (AgNF) films, and flexible interdigital electrodes was designed by layer-by-layer (LBL) assembly. The unique microstructure of PDMS effectively increases the contact area and improves sensitivity. Moreover, AgNFs were introduced into the MXene as a “bridge,” and the synergistic effect of the two further enhanced the performance of the sensor. The pressure sensor has high sensitivity (191.3 kPa–1), good stability (18,000 cycles), fast response/recovery time (80 ms/90 ms), and low detection limit (8 Pa), so it can be used for all-round monitoring of the human body. Sensing arrays were integrated with a wireless transmitter as an intelligent artificial electronic skin for spatial pressure mapping and human–computer interaction sensing. Moreover, we develop a smart glove by a simple method, combining it with a 3D model for wireless accurate detection of hand poses. This provides ideas for hand somatosensory detection technology, leading to health monitoring, intelligent rehabilitation training, and personalized medicine.

“…The as-prepared fabric electrodes formed a parallel capacitor with a minimum measurable distance and bending angle of 19 μm and 0.05°, respectively, which can be applied to evaluate training effects of rehabilitation by monitoring the contraction of abdominal muscles at standing, sitting, and lying states. Due to the strong tendency of stacking up of conductive nanosheets [ 225 ], fabric sensors based on graphene/MXenes still suffer from limited sensitivity and detection range, which may be ameliorated by microstructures constructing of the fabric coatings despite at a higher cost [ 212 , 214 ].…”

“…The resulting bark-shaped MXene/CNF material exhibited excellent breathability. Zheng et al 138 prepared a CNT/Ti 3 C 2 T x CNF by the same method, and it also displayed outstanding performance. This kind of sensor can monitor finger presses, pulse, and walking, or observe steady electrical currents.…”

Recently, there has been a huge demand for flexible pressure sensors in various fields, including smart wearable textiles, health detection, and electronic skin. Flexible pressure sensors have been developed with high sensitivity, wide sensing range, rapid response time, and excellent cycling stability. Currently, emerging conductive materials include two-dimensional transition metal carbides and nitrides (MXenes). These materials have attracted immense attention in the field of flexible pressure sensors due to their high electrical conductivity, large specific surface area, and satisfactory hydrophilicity. This review highlights different preparation methods of MXene composites. It also summarizes the nanostructure design of pressure-sensitive materials to improve the performance of flexible pressure sensors for soft electronics applications. This review provides a comprehensive overview of the progress of MXene composites and their prospects in the area of flexible pressure sensors and summarizes the applications and challenges of these sensors in intelligent wearables. This review also proposes some suggestions for developing a new generation of intelligent textiles.
