1、基于耳垂脉搏间接检测血压的低功耗传感技术研究中文摘要基于耳垂脉搏间接检测血压的低功耗传感技术研究中文摘要血压作为人体最重要的生理参数之一，反应了人体血管和心脏的健康状况。对于诊断疾病、观察治疗、预防检测等方面都有很重要的指导意义。本文分析了血压测量技术的发展和各种血压测量方法的优缺点。基于NIRS、血液动力学、生物理论的研究，建立了根据脉搏波传导时间实现无创血压测量的数学模型，提出了基于耳垂脉搏间接测量血压的方法。利用波长为850nm的近红外LED对管，功能强大的低功耗32位MCUSTM32F107对提出的理论进行了设计论证。并开展了两个对比实验：实

2、验一对3名测试者进行了设计仪器的血压测定，与九安电子血压计测得数据进行对比，验证了本文测量方法的可行性。实验二对九安电子血压计和本文设计仪器进行了功耗对比，验证了传感和数据处理方式的低功耗的特性。关键词：耳垂，近红外，血压测量，低功耗作者：屈毅成指导教师：李文石IAbstractALow-powerSensingTechnologyResearchOnBloodPressureMeasureByEarlobeALow-powerSensingTechnologyResearchOnBloodPressureMeasurementByEarlobeAb
