摘　　要：动脉脉搏波速率(PWV)测量在评价动脉弹性和硬度中具有重要的理论意义和应用价值;针对远程健康监护需求的日益扩大,采用硬件低功耗设计技术同软件节能技术相结合的方法,提出了一种基于无线传感器网络的脉搏波监测系统的硬、软件实现方案;实验结果表明,该系统能够实现对人体动脉脉搏波信号的实时检测,具有较强的抗干扰能力,重复性误差得到了显著的改善,基本保持在0.35%以下;脉搏波信号中所包含的生理信息,有助于对人体动脉硬化的检测,具有较好的应用价值。Arterial pulse wave velocity （PWV） measurement is of great theoretical importance and practical value in evaluating the arteri- al elasticity and stiffness. By combining hardware low power design technique and software energy saving technique, a hardware and soft- ware solution of pulse waves monitoring system based on wireless sense network has been proposed. The experimental result shows that the system can capture pulse wave signal accurately in real time. It features higher anti jamming capability. Repeatability error has been signif- icantly improved, remaining below 0.35 percent. The physiologic signal included in signals contribute greatly to detect arteriosclerosis, with practical application value.
