Опубликована: Март 6, 2025

Endowing flexible sensors with self-powering capabilities is of significant importance. However, the thermoelectric conversion gels reported so far suffer from limitations insufficient flexibility, signal distortion under repetitive deformation, and comprehensive performance, which seriously hinder their wide application. In this work, we designed prepared eutectogels by an ionic liquid a polymerizable deep eutectic solvent (PDES), exhibit good mechanical properties, adhesion, excellent response performance. The Seebeck coefficient (Si) can reach 30.38 mV K-1 at temperature difference 10 K. To amplify self-powered performance individual gel units, assembled them into arrays further sensors. combination K-means clustering algorithm machine learning filter out noise traditional improve consistency signals, thereby enabling prediction absolute conditions or 20 K difference. This study also demonstrates potential application these in sensing.

An Antifreeze Gel as Strain Sensors and Machine Learning Assisted Intelligent Motion Monitoring of Triboelectric Nanogenerators in Extreme Environments

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 27, 2025

Abstract Traditional hydrogels tend to freeze and lose performance at low temperatures, limiting their applications. Additionally, need exhibit hysteresis, excellent cycling stability, self‐adhesion ensure high‐quality signal acquisition in complex environments. To address this challenge, study designed a dual‐network gel glycerol (Gly)/H 2 O solvent system. Due the combination of chemical physical crosslinking (hydrogen bonding electrostatic interactions), resulting exhibits skin‐adaptive modulus, high anti‐freezing ability, body temperature‐induced adhesion, electrical performance, making it suitable for wearable sensors temperatures. Based on gel, single‐electrode triboelectric nanogenerator (gel‐TENG) is developed, achieving efficient conversion mechanical energy into energy. Further applied smart insole, successfully enabled real‐time visualization plantar pressure distribution skiing motion recognition. Using random forest machine learning algorithm, system accurately classified 11 basic motions, classification accuracy 97.1%. This advances flexible self‐powered systems, supporting intelligent materials research extreme

Anti-Swelling Aramid-Nanofiber-Reinforced Zwitterionic Polymer Hydrogel for Strain Sensors

Materials, Год журнала: 2025, Номер 18(8), С. 1800 - 1800

Опубликована: Апрель 15, 2025

Zwitterionic polymer hydrogels have great application prospects in wearable electronic devices due to their antifouling and excellent biocompatibility. However, its strong hydrophilicity often leads easy swelling poor mechanical properties. In this study, aramid nanofiber (ANF)-reinforced zwitterionic ion were synthesized by the one-step free radical polymerization of N-acryloyl glycinamide (NAGA), N-[Tris (hydroxymethyl) methyl] acrylamide (THMA) sulfobetaine methacrylate (SBMA) monomers presence ANFs. A large number hydrogen bonds formed between amide groups ANFs NAGA units/the hydroxyl THMA sulfonic SBMA units, which improved internal interface force hydrogel. The obtained ANF-reinforced hydrogel had an anti-swelling property, ratio tensile strength 25% 170% those without addition By introducing lithium chloride as electrolyte improve conductivity subsequently assembling it into strain sensors, exhibited a high sensitivity (GF = 1.12), short response recovery times (100 ms 150 ms), cycling stability. This work provides feasible strategy for sensors.
