ABSTRACT Flexible sensors exhibit the properties of excellent shape adaptability and deformation ability, which have been applied for environmental monitoring, medical diagnostics, food safety, smart systems, human–computer interaction. Cellulose‐based hydrogels are ideal materials fabrication flexible due to their unique three‐dimensional structure, renewability, ease processing, biodegradability, modifiability, good mechanical properties. This paper comprehensively reviews recent advances cellulose‐based in construction sensor applications. The characteristics, mechanisms, advantages prepared by physical cross‐linking, chemical cross‐linking respectively analyzed summarized detail. focus then turns research development hydrogel sensors, including sensing (pressure/strain, humidity/temperature, optical sensing), (chromium, copper, mercury ion sensing, toxic gas nitrite biosensing (glucose, antibody, cellular sensing). Additionally, limitations along with key challenges future directions, discussed. It is anticipated that this review will furnish invaluable insight advancement novel green, facilitate integration as a fundamental component multifunctional technologies, thereby expediting design innovative near future.

Abstract Micro‐electrocorticography (micro‐ECoG) with superior temporal and spatial resolution plays a critical role in precise brain mapping decoding of activities. However, due to inevitable device‐brain displacement cerebrospinal fluid, the weak physical attachment micro‐ECoG devices on cortical arachnoid tissue cannot ensure stable neural interface achieve durable reliable ECoG recording over time. Herein, robust is explored using bio‐adhesive hydrogel patch for chronic recording. To overcome challenges dimensional instability hydrogels, such as swelling shrinkage, which would impede safe integration fragile surface, non‐deformable developed through rational design balanced molecular chain topology resist changes. The multifunctional demonstrates desired merits including rapid wet‐tissue adhesion (within 30 s), anti‐postoperative adhesion, excellent biocompatibility, ease surgical handling, scalability large‐scale production. Compared conventional or contractile surface can effectively inhibit fibrous capsule formation glial cell recruitment. Furthermore, long‐term recordings from integrated patches demonstrate stability high‐fidelity electrophysiological signals, making it promising advancement chronic, durable, applications.

Abstract Conductive hydrogels are a class of multifunctional composites constructed by introducing conductive components into three‐dimensional polymer network, combining the high water‐content, stretchability, and biocompatibility traditional hydrogels. In recent years, researchers have developed stimuli‐responsive (SRCHs) through molecular functionalization design, which can respond to external stimuli such as mechanical stress, temperature, pH, light, electric field, etc., realize electrical signal output or behavior modulation, so satisfy requirements smart devices for dynamic sensing active response materials. Thanks synergistic effect environmental responsiveness conductivity, SRCHs show broad application prospect in actuation. However, due complexity environment, it is still difficult utilize materials construct sophisticated devices. This paper systematically reviews progress material design actuation applications past five focuses on their mechanisms performance optimization strategies, summarizes current challenges future development directions, with view providing theoretical references technological inspirations next‐generation

Wearable devices have revolutionized real-time health monitoring, yet challenges persist in enhancing their flexibility, weight, and accuracy. This paper presents the development of a wearable device employing conductive polyacrylamide-lithium chloride-MXene (PLM) hydrogel sensor, an electronic circuit, artificial intelligence (AI) for gait monitoring. The PLM sensor includes tribo-negative polydimethylsiloxane (PDMS) tribo-positive polyurethane (PU) layers, exhibiting extraordinary stretchability (317% strain) durability (1000 cycles) while consistently delivering stable electrical signals. weighs just 23 g is strategically affixed to knee brace, harnessing mechanical energy generated during motion which converted into These signals are digitized then analyzed using one-dimensional (1D) convolutional neural network (CNN), achieving impressive accuracy 100% classification four distinct patterns: standing, walking, jogging, running. demonstrates potential lightweight energy-efficient sensing combined with AI analysis advanced biomechanical monitoring sports healthcare applications.
