摘要
提出一种全新的基于柔性薄膜材料的高灵敏度、多参数汗液成分分析传感器,对敏感材料的特性及高灵敏度捕获机理进行了研究分析,设计了一种抗干扰信号采集电路,最终完成传感器样品制备,并搭建测试环境,对其关键性能指标进行了测试.结果表明,汗液传感器可实现对钾离子、钠离子、葡萄糖 3 种汗液成分的实时监测,在检测灵敏度和抗干扰性能上达到较好水平,与传统的检测仪器或单参数汗液传感器检测方法相比,在实用性上有很大的提升.
Abstract
This paper proposes a new high-sensitivity,multi-parameter sweat composition analysis sensor utili-zing flexible thin film materials.The characteristics of the sensitive materials and high-sensitivity capture mecha-nism were studied and analyzed.Subsequently,an anti-interference signal acquisition circuit was designed.Finally,a sample sensor was prepared,and a test environment was set up to test its key performance indicators.The results showed that the sweat sensor could realize the real-time monitoring of potassium ion,sodium ion,and glucose,which are components of sweat,with good detection-sensitivity and anti-interference-performance levels.The prac-ticability was much better than that of atraditional detection instrument or single-parameter sweat-sensor detection method.
