Abstract Electronic skin (e‐skin), a skin‐like wearable electronic device, holds great promise in the fields of telemedicine and personalized healthcare because its good flexibility, biocompatibility, conformability, sensing performance. E‐skin can monitor various health indicators human body real time over long term, including physical (exercise, respiration, blood pressure, etc.) chemical (saliva, sweat, urine, etc.). In recent years, development materials, analysis, manufacturing technologies has promoted significant e‐skin, laying foundation for application next‐generation medical devices. Herein, properties required e‐skin monitoring devices to achieve long‐term precise summarize several detectable field are discussed. Subsequently, applications integrated systems reviewed. Finally, current challenges future directions this This review is expected generate interest inspiration improvement systems.

Abstract Ubiquitous anti‐counterfeiting materials with a rapidly rising annual consumption (over 10 m 2 ) can pose serious environmental burden. Biobased cellulosic birefringence offer attractive sustainable alternatives, but their scalable solvent‐free processing remain challenging. Here, dynamic chemical modification strategy is proposed for multi‐modal melt‐processing of birefringent eco‐friendly anti‐counterfeiting. Relying on the thermal‐activated covalent‐locking spatial topological structure preferred oriented cellulose, balances contradiction between strong confinement long‐range ordered structures and molecular motility required entropically‐driven reconstruction. Equipped customizable forms including mold‐pressing, spinning, direct‐ink‐writing, blade‐coating, exhibit wide color gamut, self‐healing efficiency (94.5%), recyclability, biodegradability. Moreover, diversified flexible elements facilitate fabrication compatibility universal techniques, thereby enabling versatile programmable The expected to provide references cellulose promote innovation in industry.

Abstract Stretchable and self-adhesive conductive hydrogels hold significant importance across a wide spectrum of applications, including human–machine interfaces, wearable devices, soft robotics. However, integrating multiple properties, such as high stretchability, strong interfacial adhesion, self-healing capability, sensitivity, into single material poses technical challenges. Herein, we present multifunctional hydrogel based on poly(acrylic acid) (PAA), dopamine-functionalized pectin (PT-DA), polydopamine-coated reduction graphene oxide (rGO-PDA), Fe 3+ an ionic cross-linker. This exhibits combination stretchability (2000%), rapid (~ 94% recovery in 5 s), robust self-adhesion to various substrates. Notably, the demonstrates remarkable skin adhesion strength 85 kPa, surpassing previous adhesive hydrogels. Furthermore, incorporating rGO within network creates electric pathways, ensuring excellent conductivity (0.56 S m –1 ). Consequently, these exhibit strain-sensing properties with increase gauge factor (GF) 14.6, covering extensive detection range ~ 1000%, fast response (198 ms) exceptional cycle stability. These can be seamlessly integrated motion sensors capable distinguishing between or subtle movements human body.

Abstract Cellulose consists of a natural, rigid polymer that is widely used to improve the mechanical and water‐holding properties hydrogels. However, its abundant hydroxyl groups make it highly absorbent free water, leading swelling behavior. This increased water content will also decrease adhesive performance. In this study, cellulose successfully hydrophobically modified reduce absorption water. Gelatin then cross‐linked with through Schiff‐base reaction, resulting in bound content. significantly enhances resistance permeability, improves freeze–thaw stability hydrogel. Due internal hydrophobicity, molecules can quickly penetrate into interior, reducing their residence time on hydrogel surface. allows maintain high adhesion natural environments, achieving an strength up 3.0 MPa wood bamboo‐based materials. The retain even after prolonged exposure humid environment. Additionally, Na + ions enhance electrical conductivity sensitivity (gauge factor (GF) = 1.51), demonstrating potential applications flexible sensing.
