Ionic skin can mimic human to sense both temperature and pressure simultaneously. However, a significant challenge remains in creating precise ionic skins resistant external stimuli interference when subjected pressure. In this study, we present an innovative approach address by introducing highly anisotropic nanofluidic (ANIS) composed of carboxylated cellulose nanofibril (CNF)-reinforced poly(vinyl alcohol) (PVA) nanofibrillar network achieved through straightforward one-step hot drawing method. The inherent nanostructures endowed the ANIS with modulus (20.9 ± 4.9 MPa) comparable that cartilage skin, alongside higher fracture energy (41.4 0.3 kJ/m2) fatigue threshold (1360 J/m2). Incorporating CNF not only improves negative potential but also increases conductivity up 0.001 S/cm, even at very low concentration (1.0 × 10–6 M). Furthermore, exhibits pressure-independent sensitivity due its high deformation-resistant performance. Thus, work introduces facile strategy for fabricating thermosensing properties, promising prospects practical healthcare applications.

Abstract Polydimethylsiloxanes (PDMS) foam as one of next‐generation polymer materials shows poor surface adhesion and limited functionality, which greatly restricts its potential applications. Fabrication advanced PDMS with multiple functionalities remains a critical challenge. In this study, unprecedented self‐adhesive are reported worm‐like rough structure reactive groups for fabricating multifunctional nanocomposites decorated MXene/cellulose nanofiber (MXene/CNF) interconnected network by facile silicone foaming dip‐coating strategy followed silane modification. Interestingly, such produces strong interfacial the hybrid MXene/CNF nano‐coatings. Consequently, optimized have excellent super‐hydrophobicity (water contact angle ≈159 o ), tunable electrical conductivity (from 10 −8 to S m −1 stable compressive cyclic reliability in both wide‐temperature range −20 200 C) complex environments (acid, sodium, alkali conditions), outstanding flame resistance (LOI value >27% low smoke production rate), good thermal insulating performance reliable strain sensing various stress modes environmental conditions. It provides new route rational design development versatile multifunctionalities promising applications intelligent healthcare monitoring fire‐safe insulation.

Although skin-like sensors that can simultaneously detect various physical stimuli are of fair importance in cutting-edge human-machine interaction, robotic, and healthcare applications, they still face challenges facile, scalable, cost-effective production using conventional active materials. The emerging two-dimensional transition metal carbide, Ti3C2Tx MXene, integrated with favorable thermoelectric properties, metallic-like conductivity, a hydrophilic surface, is promising for solving these problems. Herein, multifunctional designed to precisely distinguish temperature pressure without cross-talk by decorating elastic porous substrates MXene sheets. Because the combination conductive thermally insulating, elastic, substrate integrates efficient Seebeck piezoresistive effects, resultant sensor exhibits not only an ultralow detection limit (0.05 K), high signal-to-noise ratio, excellent cycling stability but also sensitivity, fast response time, outstanding durability detection. Based on impressive dual-mode sensing properties independent detections, multimode input terminal electronic skin created, exhibiting great potential robotic interaction applications. This work provides scalable fabrication tactile detecting distinguishing stimuli.

They also shown promising potential overcome disadvantages of traditional electronic devices (e.g., energy-consuming operation adverse humidity interference). Herein, we constructed a green alga-inspired nanofluidic system based on Janus dual-field heterogeneous membrane (i.e., J-HM), which can function underwater as an visual platform for light perception through enhanced active transport. The J-HM was obtained sequentially assembled MXene Cu-HHTP metal–organic framework reaction between 2,3,6,7,10,11-hexahydroxytriphenylene hydrate (HHTP) Cu2+) building units. Due formed temperature gradient intramembrane electric field caused by localized thermal excitation efficient charge separation under illumination, thermo-osmotic photo-driven forces are generated preferential cation transport from MXene. Furthermore, unidirectional be self-diffusion concentration gradient. Then, perceptions at illumination conditions explored, showing nearly linear correlation with intensity. Finally, it is demonstrated that achieve object shape, definition, distance recognition using defined pixelated matrix, impetus develop ionic signal transmission sensing systems.
