基于聚乙烯醇/聚吡咯导电有机凝胶的合成及其在人体活动监测中的应用
Synthesis of Polyvinyl Alcohol/Polypyrrole Conductive Organogel and Its Application in Human Activity Monitoring
摘要
Abstract
To address the shortcomings of traditional hydrogels in terms of mechanical performance and environmental stability,a new conductive organogel based on polyvinyl alcohol(PVA)and polypyrrole(PPy)was prepared in this study.By introducing dimethyl sulfoxide(DMSO)as a solvent,the mechanical strength and durability of the gel were significantly improved.Various characterization techniques,including infrared spectroscopy,thermogravimetric analysis,and scanning electron microscopy were used to characterize this conductive organogel.The experimental results showed that the prepared organogel exhibited optimal performance at PVA concentration level of 8%(m/m),with an average pore size of 5.2 μm and a conductivity of 0.65 S/cm.As a wearable strain sensor,the PVA/PPy organogel demonstrated excellent sensitivity and responsiveness,capable of precisely detecting joint and muscle movements as well as subtle physiological signals such as pulse and vocal cord vibrations.Notably,the gel maintained stable sensing performance even after 48 h at room temperature,showing outstanding environmental adaptability and long-term use potential.This innovative material design provided robust technical support for smart healthcare,health monitoring,and human-machine interaction,showing broad application prospects.关键词
