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.

In conventional double network (CDN) hydrogels, dense chemical cross-linking in the first frequently induces structural imperfections, resulting significant energy dissipation and substantial hysteresis under stress. To improve uniformity, spatial heterogeneities can be minimized by introducing mobile cross-linking, which facilitates creation of a more homogeneous network. Herein, we employed polymerization-induced entanglements (PIEs) strategy to tune from traditional net-like fabric-inspired topology, simultaneously promoting greater chain entanglement with second This innovative approach enables PIEs DN hydrogels exceptional performance, including significantly reduced (0.15), high tensile strength (1.25 MPa), excellent toughness (5800 J/m2), overcoming long-standing trade-off between observed CDN offering insights avenues for expanding hydrogel applications.

In this work, a supertough, self-healable, and extreme-environment-tolerable liquid metal (LM) composite organohydrogel was fabricated by dispersing LM particles (LMPs) with water-soluble starch (WS) leveraging multilevel hydrogen-bonding interactions. Attributed to the cooperation of strong dual-hydrogen bonds weak monohydrogen bonds, obtained an outstanding tensile strength 2.0 ± 0.13 MPa toughness 16.0 1.0 MJ m–3, as well desirable self-healing ability. The strain sensor has high gauge factor (GF) 15.08 along large detection range (0–1159%), demonstrating its sensitivity. It successfully applied for manipulator gesture in harsh environments, showing excellent resolution sensing stability wide temperature (−20 50 °C). This work provides new avenue preparing multifunctional gels, great promise next-generation wearable electronics.
