Flexible wearable electronics face critical challenges in achieving reliable physiological monitoring, particularly due to the trade-off between sensitivity and durability flexible electrodes, compounded by mechanical modulus mismatch with biological tissues. To address these limitations, we develop an anti-freezing ionic hydrogel through a chitosan/acrylamide/LiCl system engineered via solution post-treatment strategy. The optimized exhibits exceptional conductivity (24.1 mS/cm at 25 °C) excellent cryogenic tolerance. Leveraging attributes, construct gel-based triboelectric nanogenerator (G-TENG) that demonstrates ultrahigh (1.56 V/kPa) under low pressure. device enables precise capture of subtle vibrations frequency 1088 Hz signal-to-noise ratio 16.27 dB operational stability (>16,000 cycles), successfully differentiating complex activities including swallowing, coughing, phonation. Through machine learning-assisted analysis, achieves 96.56% recognition accuracy for five words good signal ability different ambient sound scenarios. This work provides paradigm designing environmentally adaptive sensors interfacial engineering ion transport optimization.

As flexible and wearable electronics play more important role in smart watches, glass virtual reality, the power supply to have been revealed attentions for long-term usage continuous healthy monitoring. To overcome challenge, self-powered BTO-PVDF/PDMS piezoelectric-triboelectric electric hybrid generators (BPP-HNG) are developed human gesture monitoring machine interaction (HMI) application without external supply. BPP-HNG based on BTO-PVDF PDMS films prepared by sol-gel spin-coating method. When BTO content is 20 wt.%, exhibits better electrical performance with an output voltage of 20.51 V. A real-time system designed interaction, which able control motion robot finger through BPP-HNG. could monitor recognize various gestures real time, enabling synchronization between hand robot's hand. With convergence AI technology big data, HMI expected realize potential smarter intuitive interactions.

Abstract Transient electronics with degradability or dissolvability on demand possess remarkable characteristics for wearable, bioelectronic, and implanted electronic devices. While synthetic materials have made significant progress in stretchability, they suffer from intrinsic limitations, including low degradation rates, poor mechanical compliance, high production cost, which restrict the growth of transient Herein, a versatile fabrication strategy is presented that combine resilient biopolymer substrate (gelatin biogels) liquid metal (Galinstan). The circuits gelatin biogel‐based are mechanically durable, exhibiting good compliance irregular deformable surfaces, thus can withstand long‐term exposure to dynamic deformation (about 60 000 cycles at strain 50%). More importantly, biogels naturally derived endowed thermally reversible gelling, enables on‐demand rapid dissolution recycling materials. As proof‐of‐concept, circuit‐based capacitive sensors, be degraded within 20 s, fabricated monitoring finger touching, morse code generation, electrical touchpad. Such provides guideline designing combination gels metal, this approach anticipated find applications human–machine interfaces wearable
