Hydrogels present attractive opportunities as flexible sensors due to their soft nature and tunable physicochemical properties. Despite significant advances, practical application of hydrogel-based sensor is limited by the lack general routes fabricate materials with combination mechanical, conductive, biological Here, a multi-functional hydrogel reported in situ polymerizing acrylamide (AM) N,N'-bis(acryloyl)cystamine (BA) dynamic crosslinked silver-modified polydopamine (PDA) nanoparticles, namely PAM/BA-Ag@PDA. Compared traditional polyacrylamide (PAM) hydrogel, BA-Ag@PDA nanoparticles provide both high-functionality crosslinks multiple interactions within PAM networks, thereby endowing optimized PAM/BA-Ag@PDA significantly enhanced tensile/compressive strength (349.80 kPa at 383.57% tensile strain, 263.08 90% compressive strain), lower hysteresis (5.2%), improved conductivity (2.51 S m

Deep‐Learning Integrated Bioelectronic‐Tissue Interface for Cardiovascular Diagnosis and Prognosis

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

Abstract Bioelectronic‐tissue interfaces hold promise for monitoring electrophysiological signals and diagnosing cardiovascular diseases. However, current lack the required tissue adaptability robust adhesion in dynamic physiological environment of cardiac tissue, leading to low‐quality signal feedback that hinders precise diagnostics prognosis conditions. To address these challenges, a bioadhesive polyampholyte‐based electronic interface (BPAEI) is developed featuring polyampholyte (PA) network interpreting with amino‐functionalized hyaluronic acid (BPA‐NH 2 ) seamless integration eutectic gallium–indium (EGaIn) liquid metal (LM). This on‐tissue bioelectronic offers high adaptability, de‐swelling, long‐term stability, sustaining over 1000 cycles minimal residual strain less than 2% resistance change. Through rapid‐drying cross‐linking mechanism, BPAEI forms an instant adhesive tailored cycles, demonstrating interfacial toughness 283.18 Jm −2 , durable strength change even after peel‐off tests. Furthermore, enables triggerable benign detachment exhibits excellent biocompatibility. Benefiting from advanced properties, can be further integrated deep‐learning model diagnosis prognosis, facilitating early warnings myocardial infarction. These advancements pave way next‐generation implantable bioelectronics, offering intelligent improved outcomes disease management.

Preparation and Performance of PVDF-HFP/PAN-Based Gel Polymer Electrolytes

Gels, Journal Year: 2025, Volume and Issue: 11(5), P. 317 - 317

Published: April 24, 2025

Solid-state electrolytes are widely expected to enhance the performance of lithium-ion batteries, providing higher energy density and improved safety. However, challenges still need be solved in their practical application due low ionic conductivity high interfacial resistance at room temperature. In this study, we successfully developed a high-performance gel polymer electrolyte (GPEs) by blending poly(vinylidene fluoride-co-hexafluoropropylene)(PVDF-HFP) polyacrylonitrile (PAN) through UV curing, cross-linking with ethoxylated trimethylolpropane triacrylate (ETPTA), incorporating Li6.4La3Zr1.4Ta0.6O12 (LLZTO). At temperature, GPEs was 2.8 × 10−4 S/cm, transference number 0.6. Moreover, during lithium plating/stripping tests, assembled Li/PPEL/Li symmetric cell exhibited stable cycling for up 600 h current 0.1 mA/cm2. Notably, enabled LiFePO4/GPEs/Li battery achieve excellent performance, delivering discharge capacities temperature (164.3 mAh g−1 C 88.8 1 C), capacity retention 89.4% after 200 cycles 0.5 C. Therefore, solid-state batteries using exhibit including adequate stability.
