Abstract Flexible wearable sensors with bimodal functionality offer substantial value for human health monitoring, as relying on a single indicator is insufficient capturing comprehensive physiological information. However, face multiple challenges in practical applications, including mutual interference between various modalities, and integration of excellent mechanical properties, interfacial adhesion, environmental adaptability biocompatibility. Herein, the multifunctional hydrogel, synthesized through radical grafting supramolecular self‐crosslinking reactions, exhibits thermal sensitivity (TCR = −1.70% °C −1 ), high toughness (9.31 MJ m − 3 wide strain range (0–600%), outstanding adhesion strength (36.07 kPa), antifreeze, visualization, water retention, biocompatibility, antibacterial antioxidant capabilities. Leveraging its conductivity, this hydrogel can be applied electroluminescent, triboelectricity, electromyography message encryption. Moreover, fabricated smart temperature monitoring. To avoid two signals, system “IS”‐shaped configuration innovatively designed based finite element simulation results. The flexible circuit modules, data transmission form closed‐loop platform rehabilitation training patients arthritis or joint surgery. This strategy establishes decoupling self‐calibrating utilizing material to accurately detect parameters, advancing electronics personalized medicine.

A conductive hydrogel is widely used in flexible electronics, strain sensors, and energy harvesting. However, poor mechanical property, low sensitivity, slow response time limit their application sensors triboelectric nanogenerators (TENG). In order to address these issues, using polyacrylamide (PAM), cellulose nanofibers (CNF), MXene composites as preparation materials, an electrohydrodynamic (EHD) printing method assisted in-situ photopolymerization proposed fabricate a PAM/CNF/MXene (PCM) hydrogel. the precursor solution of orderly arranged under influence electrostatic field force, thereby forming stable channel MXene. Compared with traditional technology, conductivity hydrogels fabricated through this improved by 58%. Hydrogen bond formed between CNF PAM, which improves properties hydrogels. can form interpenetrating networks PAM/CNF hydrogel, providing channels for improving its sensing performance. The structure endows PCM outstanding (550% tensile strain). Strain based on exhibits eminent sensitivity (6.73 gauge factor), rapid response/recovery (100/110 ms), broad detection range (1% ∼ 550%). CM-TENG shows excellent electric output performance (67.5 V open circuit voltage at 100% addition, sensor applied human motion monitoring information transmission, self-powered PCM-TENG writing recognition. has prospects supply.
