摘要
心血管疾病对人类健康的威胁日趋严重,因而对心血管状态的实时监测变得尤为重要。摩擦电脉搏波传感器(TGP-s)基于摩擦电纳米发电机工作原理,用聚对苯二甲酸乙二醇酯(PET)、聚四氟乙烯(PTFE)为主要材料,通过对PET压膜、涂抹导电银胶和对PTFE用乙醇清洗、蒸镀铜薄层以及把处理后的PET和PTFE用铜胶带封装和焊接电极处理研制而成,具有成本低、制备工艺简单、柔性可穿戴、高灵敏、无需外接复杂电路、对人体是无伤害等优势。实验结果表明,TGP-s采集的信号稳定且准确,使用TGP-s在人体桡动脉处进行日常的无创实时脉搏监测及定性评估是有效的,也是可行的。
With the increasingly serious threat of cardiovascular disease to human health, the real-time monitoring of cardiovascular status is particularly emphasized. Therefore, it is of great significance to use a flexible, wearable, highly sensitive sensor to monitor human physiological signal. In the study, triboelectric pulse sensor(TGP-s) is made of common plastic PET and PTFE based on the working principle of triboelectric nanogenerator. The PET goes through film pressing and coating with conductive silver glue. The PTFE is cleaned with ethanol and evaporated with thin copper layer. Finally, the treated PET and PTFE are sealed with copper tape and welded electrode. It has the advantages of low cost, simple preparation process, flexible wearability, high sensitivity, simple external circuit, complete safety and so on. Data analysis shows that the signal collected by TGP-s is stable and accurate, and it is effective and feasible to use TGP-s for daily noninvasive real-time pulse monitoring and qualitative evaluation at human radial artery.
