“…Compared with untreated nonwoven fabrics, all the pressure sensors exhibit a larger water contact angle, with the water contact angle of the MPF3 pressure sensor reaching 110.9° (Figure 3K), suggesting enhanced hydrophobicity. This improvement was attributed to the contribution from PEDOT:PSS, consistent with similar findings in other MXene/PEDOT:PSS‐based composites 41,42 . Additionally, the good hydrophobicity of device is advantageous for avoiding dust impurity deposition and enhancing its self‐cleaning performance, making it suitable for wearable applications.…”

Flexible, breathable, and highly sensitive pressure sensors have increasingly become a focal point of interest due to their pivotal role in healthcare monitoring, advanced electronic skin applications, and disease diagnosis. However, traditional methods, involving elastomer film‐based substrates or encapsulation techniques, often fall short due to mechanical mismatches, discomfort, lack of breathability, and limitations in sensing abilities. Consequently, there is a pressing need, yet it remains a significant challenge to create pressure sensors that are not only highly breathable, flexible, and comfortable but also sensitive, durable, and biocompatible. Herein, we present a biocompatible and breathable fabric‐based pressure sensor, using nonwoven fabrics as both the sensing electrode (coated with MXene/poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate [PEDOT:PSS]) and the interdigitated electrode (printed with MXene pattern) via a scalable spray‐coating and screen‐coating technique. The resultant device exhibits commendable air permeability, biocompatibility, and pressure sensing performance, including a remarkable sensitivity (754.5 kPa−1), rapid response/recovery time (180/110 ms), and robust cycling stability. Furthermore, the integration of PEDOT:PSS plays a crucial role in protecting the MXene nanosheets from oxidation, significantly enhancing the device's long‐term durability. These outstanding features make this sensor highly suitable for applications in full‐range human activities detection and disease diagnosis. Our study underscores the promising future of flexible pressure sensors in the realm of intelligent wearable electronics, setting a new benchmark for the industry.

Due to its superior advantages in terms of electronegativity, metallic conductivity, mechanical flexibility, customizable surface chemistry, etc., 2D MXenes for nanogenerators have demonstrated significant progress. In order to push scientific design strategies for the practical application of nanogenerators from the viewpoints of the basic aspect and recent advancements, this systematic review covers the most recent developments of MXenes for nanogenerators in its first section. In the second section, the importance of renewable energy and an introduction to nanogenerators, major classifications, and their working principles are discussed. At the end of this section, various materials used for energy harvesting and frequent combos of MXene with other active materials are described in detail together with the essential framework of nanogenerators. In the third, fourth, and fifth sections, the materials used for nanogenerators, MXene synthesis along with its properties, and MXene nanocomposites with polymeric materials are discussed in detail with the recent progress and challenges for their use in nanogenerator applications. In the sixth section, a thorough discussion of the design strategies and internal improvement mechanisms of MXenes and the composite materials for nanogenerators with 3D printing technologies are presented. Finally, we summarize the key points discussed throughout this review and discuss some thoughts on potential approaches for nanocomposite materials based on MXenes that could be used in nanogenerators for better performance.

“…Therefore, this kind of material is increasingly used in the preparation of W-TENGs. [248][249][250] Xu et al, 251 used solution blowing technology (SBS) 252 to blow a mixed solution of MXenes and PVDF on the surface of conductive fabrics to prepare a full-ber, single-electrode W-TENG. Compared with the W-TENG of the original PVDF, the W-TENG based on PVDF-MXenes can generate a voltage of about 90 V, which is about 350% higher than that of the non-added PVDF.…”
