“…5b. Notably, the 1000% sensing range was larger than other studies reported in the literature 4,32,34,44,45 (detailed information is given in Table S3, ESI†). It can be seen that the Δ R / R 0 value at 50% strain was not obvious compared with the other degrees of strain, but as the strain gradually rose, Δ R / R 0 became increasingly pronounced due to the fact that a larger degree of strain corresponded to a greater degree of disruption in the conductive network.…”

“…The (104) peak in the MAX phase disappeared after solution etching, demonstrating complete removal of Al and successful formation of Ti 3 C 2 T x MXene. 38 XPS measurement was performed on the MXene to determine the type of surface functionalities. The survey scan spectrum revealed that the sample mainly contained Ti, C, O, and F elements (Figure 1e).…”

Tight stacking between two-dimensional (2D) sheet-like materials, such as graphene, in the solid state is a major challenge hindering their applications, especially in the gas sensing field. Here, we report on a TiO 2 nanoparticle-spaced reduced graphene oxide (RGO) assembly for the design of highly sensitive gas sensors. The TiO 2 nanospacers are derived from a 2D MXene that is intercalated between RGO sheets. The produced TiO 2 -spaced RGO assembly exhibits a uniform nanoparticle distribution and highly wrinkled RGO sheets that interconnect in micrometer-scale pores. The space limitation between adjacent RGO sheets can restrict the particle growth and lead to the formation of TiO 2 nanoparticles with uniform diameters of ca. 6.2 nm. The sensitivity of the TiO 2 -spaced RGO sensor to NO 2 improved by over 400% in comparison with pure RGO due to the more available surface area and active adsorption sites. Furthermore, fast response and recovery, excellent selectivity and flexibility, and reliable workability in a humid environment (with the relative humidity ranging from 5 to 95%) were also simultaneously achieved, demonstrating great potential for next-generation wearable sensors.

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.
