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.

The increasing demand for flexible wearable electronic devices has prompted the rapid development of pressure sensors capable monitoring a range human movements and physiological signals. However, an number studies are requiring with high performance while also seeking low-cost, large-scale, or even disposable manufacturing methods. In this study, we propose capacitive sensor based on tailorable materials. employs polyurethane sponge coated inert metals, namely copper nickel (Cu@Ni/PUS), as electrodes polyimide (PI) film dielectric layer. prepared exhibit sensitivity (0–17.5 kPa, 49.14% kPa–1), response time (80 ms), low hysteresis (6.49%), stability. Furthermore, Cu@Ni/PUS was integrated into insulated glove, innovative, improved Morse code encoding scheme developed. By combining CNN-TCN dual-channel neural network model, achieved high-precision classification 26 alphabet letters (99.20%), providing method high-efficiency transmission using tactile sensors. Based these findings, developed real-time translation system that completes encryption decryption gestures. experimental results demonstrate research broad application prospects in accessible human–computer interaction individuals disabilities.

Abstract MXenes hold great promise for flexible sensors due to their outstanding electrical and mechanical properties. However, practical application in aqueous environments is often compromised by oxidation susceptibility. Here, epigallocatechin gallate (EGCG), a naturally derived compound introduced, as protective coating Ti₃C₂T x MXene nanosheets. The catechol groups EGCG form strong hydrogen bonds with MXene, significantly enhancing its resistance up 40 days. By incorporating EGCG‐coated (MXene@EGCG) dual‐crosslinked hybrid network, tough hydrogel exceptional properties, including enhanced compressibility (>95%), high compressive strength (5.43 MPa), minimal residual strain (<1%), rapid recovery within seconds developed. Furthermore, the exhibits superior sensing capabilities gauge factor exceeding 10 stretch of 3.72. This well‐designed structure also endows it low degree hysteresis sensing. In vitro experiments confirm biocompatibility, desired self‐adhesion utility platform. approach pioneers versatile transformative strategy stability engineerability, unlocking new possibilities fabricating high‐performance hydrogel‐based capable effectively dynamic strains, which may find broad applications fields multifunctional bioelectronics.

Abstract MXene films possess excellent controllable electrical conductivity, mechanical and chemical characteristics, showing great potential in the construction of new‐generation flexible wearable devices. However, achieving multifunctional applications through simple scalable methods is a major challenge. Inspired by skin tissue, pyrolysis‐MXene film (P‐MX) with randomly microspine‐like internal hollow coupled structure prepared combination interface‐induced self‐assembly, solution thermal deposition, high‐temperature pyrolysis methods. The multi‐level provides more variable conductive paths during compression ensures structural integrity under high pressure. synergistic treatment oxygen plasma polyvinyl alcohol (PVA) enhances adhesion strength highest up to 46.87 times compared single surface strategy between P‐MX sensitive components substrate. Such sensor demonstrates an extremely sensitivity (76.79 kPa −1 within 0–25.39 kPa), wide detection range (up 1275.19 fast response/ recovery time (22 ms/32 ms), cycle reliability (over 18 000 cycles). It can also perceive weak signals (12 mg/4.8 Pa). Additionally, exhibits significant increment specific capacitance. prospects human‐machine interaction, neural electrodes, motion detection. These findings open new pathways for practical application MXene‐based piezoresistive devices bioelectronics.
