Wearable devices have potential applications in health monitoring and personalized healthcare due to their portability, conformability, excellent mechanical flexibility. However, performance is often limited by instability acidic or basic environments. In this study, a flexible sensor with stability based on GaN nanoplate was developed through simple controllable fabrication process, where the linearity remained at almost 99% of original for 40 days an air atmosphere. Moreover, perfect also demonstrated acid–base environments, pH values ranging from 1 13. Based its piezotronic performance, device motion developed, capable detecting motions such as finger, knee, wrist bending, well swallowing. Furthermore, gesture recognition intelligent fall were explored bending properties. addition, warning system proposed application elders applying machine learning analyze data collected typical activities. Our research provides path stable electronics applications.

Integration of a high-entropy alloy (HEA) with nanozyme activity and piezoelectric material piezoelectricity is promising strategy to develop novel biofunctional for the repair infectious bone defects. Herein, heterojunction HEA (FeMnMoRuIr) zinc sulfide (ZnS) (HEA@ZnS) synthesized that exhibits enhanced activities. Moreover, hydrogel containing zein, sodium alginate, HEA@ZnS (ZeAHZ) antibacterial properties pro-osteogenic capability fabricated. Under acidic conditions, triggered by ultrasound, effect ZeAHZ enhances peroxidase-like sonodynamic efficiency produces large amount reactive oxygen species (ROS, ·O2- ·OH) collaboratively eliminating bacteria. superoxide-like effect-enhanced catalase-like scavenge ROS (·O2- H2O2) produce due cascade reaction, which provides favorable microenvironment cell growth. Further, generates electrical stimulation significantly promotes osteoblast proliferation differentiation. This study opens up new path designing biomaterial production/elimination pro-osteogenesis stimulation, has great potential accelerating regeneration.
