Abstract Multifunctional integration is a pivotal aspect in the development of flexible sensors that facilitate augmented interaction with physical environment. However, contemporary multifunctional face challenges arising from their complex structures and high costs. Therefore, polydimethylsiloxane (PDMS) /liquid metal (LM) films hierarchical structure prepared via gravity‐induced deposition LM are applied to sensors. PDMS/LM exhibit remarkable flexibility function as electrodes for pressure well single‐electrode mode triboelectric nanogenerator (TENG). The porous PDMS/carbon nanotube (CNT) dielectric an array developed sensing, showing commendable sensitivity (0.671 kPa −1 ) even under low pressures (0–17 kPa). Compared solid dielectrics, its improved over entire range. sensor achieves response time ≈80 ms demonstrates exceptional stability. Furthermore, when film functions TENG, it can serve self‐powered measuring dynamic forces aid material recognition assistance capacitive sensing. This study provides new perspective on simplified design

Bionic electronic skin, with its integrated biological functions, is capable of sensing and responding to external stimuli, potentially surpassing the ideal flexibility natural skin in certain aspects. Most current preparation strategies employ "bottom-up" approach, using various monomers or polymer materials construct artificial networks through physical chemical cross-linking, leading issues complexity limited performance. In this work, we adopted a "top-down" strategy, which collagen fiber network aluminum-tanned sheepskin was utilized as scaffold load itaconic acid (IA) hydroxyethyl acrylate (HEA). The subsequent situ polymerization IA HEA led formation poly(itaconic acid-co-hydroxyethyl acrylate) (P(IA-HEA)) filling among skeleton, results successful fabrication high-strength bionic based on (LIHEZ). advantage approach that it can retain structure properties give resulting LIHEZ multiple functions (e.g., electrical conductivity, adhesion, bacteriostasis, biocompatibility, environmental stability), thereby replicating even performance animal skin. demonstrated sensitive stimulus responsiveness durability could serve multimodal sensors (strain, temperature, humidity, bioelectricity) efficiently monitor human movements, physiological signals, changes temperature humidity. This diversified data collection provides reliable assurance for monitoring health. present construction method substrate not only breaks conventional single applications but also new insights selection flexible device substrates, promising be next-generation material constructing intelligent

Humidity sensors are vital for ambient monitoring, but existing focus on moisture absorption, overlooking the indispensable role of ion channels in water-electricity conversion process. Here, an ultra-miniaturized fiber humidity (MFH) sensor based near-parallel pathways is presented. The well-designed nanochannels significantly facilitate transport due to stable charge distribution and confined ions migration within nanostructure, which improves efficiency moisture-sensitive fibers. Optimized enable MFH improve response/recovery speed by ≈5 times compared disordered nanochannels. Additionally, can be woven ultra-miniaturization (0.50 mm
