Abstract The rapid development of wearable electronics, personal mobile equipment, and Internet of Things systems demands smart textiles that integrate multiple functions with enhanced durability. Herein, the study reports robust and multifunctional textiles with energy harvesting, electromagnetic interference (EMI) shielding, flame resistance, and Joule heating capabilities, fabricated by a facile yet effective integration method using the deposition of cross‐linked MXene (Ti 3 C 2 T x ), poly(

Despite the rise in Internet of Things devices and mobile electronics, devising an energy harvester with sufficient time-averaged power remains a challenge when targeting human activities. Here, we report a hybrid thermo-triboelectric generator targeting human motion with systematic optimization strategies in frequency feature-size variable spaces. The device consists of bismuth telluride (Bi2Te3) tiles with polydimethylsiloxane (PDMS) layers filled in between, thereby harvesting both thermal en

Smart textiles integrated with 2D materials are revolutionizing the field of wearable technologies by providing advanced functionalities that extend far beyond those of traditional fabrics. This review comprehensively explores cutting‐edge 2D materials, such as graphene derivatives, MXenes, and transition‐metal dichalcogenides, and highlights their unique electrical, mechanical, and thermal properties. The sophisticated methods by which these materials are embedded into textiles, including coati

Abstract The rapid advancement of high‐power, miniaturized, and integrated electronic and energy storage systems necessitates multifunctional interfaces capable of simultaneously providing thermal management, electromagnetic interference (EMI) shielding, and mechanical robustness. Phase change materials (PCMs) offer substantial latent heat storage to mitigate overheating and overcooling but suffer from leakage and interfacial instability during liquid‐solid phase transitions. Conversely, MXene‐b

Summary Despite the low cost, high power, and wide application areas, impact‐type triboelectric generators exhibit limited applicability due to the extremely short current duration, on the order of a millisecond. The high power, short lasting current peak not only results in reduced time‐averaged power output but also acts as triboelectric shock to the accompanying circuits, quickly degrading the usability of the generator. Here, we demonstrate tunable triboelectric current duration via controll

Mechanoelectric energy conversion holds promise for energy conversion and transmission devices, yet conventional configurations rely on large-area conductive materials in active regions, limiting architectural design for cutting-edge devices. Here, a rational strategy is reported to create mechanical stimuli-driven pseudo-conductive (MSPC) channels entirely from dielectric materials, eliminating the need for electrodes in active regions. An in-depth investigation of MSPC channel formation mechan
