Developing multifunctional electronic fabrics with sensing capabilities, electromagnetic interference (EMI) shielding, and Joule heating performance holds great significance for health monitoring and medical protection. However, most fabrics struggle to combine multiple functions and optimize them simultaneously. For example, achieving both high sensitivity and a wide detection range in sensing devices remains a challenge. In this paper, we present a multidimensional composite structure comprising MXene Ti 3 C 2 Tx nano lamellar, self-assembled lotus leaf-like MXene/ EGaIn and carbon nanotubes (CNTs) assembled on the surface of thermoplastic polyurethane to create a multifunctional MXene EGaIn/MXene CNT fabric (MEMC fabric). The multidimensional materials form a stable conductive network under tension. As a strain sensor, the MEMC fabric exhibits a large sensing range (0−360%) and ultra-high sensitivity (GF ∼ 114,700), making it suitable for artificial eardrum research. Additionally, MEMC demonstrates excellent EMI shielding effect (∼73 dB) and maintains good EMI shielding performance under tensile conditions. The fabric also showcases outstanding Joule heating performance (low voltage drive ∼2 V, fast heating time ∼13 s, and high heating stability ∼4000 s). This paper also demonstrates the multifunctional combination of MEMC fabrics, achieving simultaneous sensing, EMI shielding, and Joule heating functions under stretching. This work offers a forward-looking approach for constructing multifunctional composite fabrics, and the resulting MEMC composite materials hold potential applications in portable electronic devices and defense industries.

With the impetus of flexible electronics and micro‐nano fabrication technology, the human demand for flexible intelligent wearable devices is on an upsurge. In recent years, new functional fibers have undergone rapid development and emerged as an indispensable carrier of flexible wearable e‐textiles. However, to achieve their functional applications and durability, new functional fibers must possess good electrical and mechanical properties. As an emerging two‐dimensional material, MXenes have attracted immense attention for their high electrical conductivity, mechanical strength, specific surface area, adjustable surface properties, and exceptional processability. As such, MXenes have become an ideal candidate for the primary functional component of functional fibers. This paper presents a comprehensive review of research progress on MXene‐based fibers in the construction of flexible wearable electronic textiles. Firstly, we briefly outline the preparation methods of MXenes materials. Next, we summarize the processing types of MXene‐based fibers and highlight their performance parameters. Lastly, we summarize the primary application scenarios of MXene‐based fibers and anticipate the future development of flexible wearable e‐textiles.

“…This can be attributed to the physical interactions between the MXene nanosheets and WPU chains. [37] In addition, the deformation recovery performance of WPU/MXene-12% films is different from that of WPU/MXene-30% films. As demonstrated in Figure S8b,c (Supporting Information), for both WPU/MXene-12% films and WPU/MXene-30% films, their strain loading paths differ in different cycles, indicating the occurrence of hysteresis.…”

Flexible electronic sensors show great potential for health monitoring but are usually limited to single sensing functionality. To enrich their functions, complicated device configurations, sophisticated material systems, and preparation processes are typically involved, obstructing their large‐scale deployment and widespread application. Herein, to achieve a good balance between simplicity and multifunctionality, a new paradigm of sensor modality for both mechanical sensing and bioelectrical sensing is presented based on a single material system and a simple solution processing approach. The whole multifunctional sensors are constructed with a pair of highly conductive ultrathin electrodes (WPU/MXene‐1) and an elastic micro‐structured mechanical sensing layer (WPU/MXene‐2), with the human skin serving as the substrate for the whole sensors. The resultant sensors show high pressure sensitivity and low skin‐electrode interfacial impedance, enabling to synergetically monitor both physiological pressure (e.g., arterial pulse signals) and epidermal bioelectrical signals (including electrocardiograph and electromyography). The universality and extensibility of this methodology to construct multifunctional sensors with different material systems are also verified. This simplified sensor modality with enhanced multifunctionality provides a novel design concept to construct future smart wearables for health monitoring and medical diagnosis.
