Abstract Hydrogels are regarded as an ideal medium for human-machine interaction (HMI) due to their adjustable modulus and flexibility, enabling seamless with smart devices. However, in the field of medical rehabilitation, most hydrogel-based sensors simply used detect motion signals fragments rarely applied help patients rehabilitation training improve efficiency doctors' diagnosis. This is unstable sensing properties poor mechanical hydrogels. The durability greatly limits application sensors. Here, a conductive hydrogel sensor visual temperature sensitivity good (300% strain, breaking stress 0.19 MPa) fabricated by introducing polyvinyl alcohol (PVA)-borax system combined freeze-thaw physical regulation strategy. PVA/PNIPAM/PEDOT: PSS (PPP) hydrogels possess rapid response/recovery time (200 ms/200 ms), low detection limit 1% stability durability. Furthermore, integrating LabVIEW circuit program wireless transmission technology, we have developed advanced intelligent HMI capable monitoring, training, remote

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.

Abstract Myocardial infarction (MI) is a leading cause of mortality among cardiovascular diseases. Following MI, the damaged myocardium progressively being replaced by fibrous scar tissue, which exhibits poor electrical conductivity, ultimately resulting in arrhythmias and adverse cardiac remodeling. Due to their extracellular matrix‐like structure excellent biocompatibility, hydrogels are emerging as focal point tissue engineering. However, traditional lack necessary conductivity restore signal transmission infarcted regions. Imparting while also enhancing adhesive properties enables them adhere closely myocardial establish stable connections, facilitate synchronized contraction repair within area. This paper reviews strategies for constructing conductive hydrogels, focusing on application MI repair. Furthermore, challenges future directions developing discussed.
