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.

“…Even after 1 min, the angle still remains at 132.1°, and the morphology of the helical fiber is not affected (Figure 2e 2 ). 26 It is noteworthy that after 5 min, the SBBT fiber still shows a contact angle of 121.6°(Figure 2f), confirming its enduring hydrophobic nature. Moreover, the hydrophobicity of SBBT helical fibers under deformation was further evaluated.…”

The rapid development of artificial intelligent wearable devices has led to an increasing need for seamless information exchange between humans, machines, and virtual spaces, often relying on touch sensors as the primary interaction medium. Additionally, the demand for underwater detection technologies is on the rise owing to the prevalent wet and submerged environment. Here, a fiber-based capacitive sensor with superior stretchability and hydrophobicity is proposed, designed to cater to noncontact and underwater applications. The sensor is constructed using bacterial cellulose (BC)@BC/carbon nanotubes (CNTs) (BBT) helical fiber as the matrix and methyltrimethoxysilane (MTMS) as the hydrophobic modified agent, forming a hydrophobic silylated BC@BC/ CNT (SBBT) helical fiber by the chemical vapor deposition (CVD) technique. These fibers exhibit an impressive contact angle of 132.8°. The SBBT helicalfiber-based capacitive sensor presents capabilities for both noncontact and underwater sensing, which exhibits a significant capacitance change of −0.27 (at a distance of 0.5 cm). We have achieved interactive control between real space and virtual space through intelligent data analysis technology with minimal interference from the presence of water. This work has laid a solid foundation of noncontact sensing with attributes such as degradability, stretchability, and hydrophobicity. Moreover, it offers promising solutions for barrier-free communication in virtual reality (VR) and underwater applications, providing avenues for smart human−machine interfaces for submerged use.
