传感器、低功耗集成电路和无线通信方面的最新技术进步使设计低成本、微型、轻量化和智能生理传感器节点成为可能。这些节点能够感知、处理和通信一个或多个生命体征，可以无缝集成到无线个人或身体网络（wpan或wban）中，以进行健康监测。这些网络通过允许廉价、无创、连续、流动的健康监测，并通过互联网几乎实时更新医疗记录，有望彻底改变医疗保健。尽管许多正在进行的研究工作都集中在各种技术、经济和社会问题上，但为了拥有适合医疗应用的灵活、可靠、安全和节能的wban，仍然需要解决许多技术障碍。本文讨论了实现问题，并描述了作者用于健康监测的原型传感器网络，该网络利用现成的802.15.4兼容网络节点和定制的运动和心脏活动传感器。本文介绍了系统的结构、硬件和软件结构，以及作者在时间同步、电源管理和片上信号处理方面的解决方案。(c) 2006 Elsevier B.V.版权所有
Recent technological advances in sensors, low-power integrated circuits, and wireless communications have enabled the design of low-cost, miniature, lightweight, and intelligent physiological sensor nodes. These nodes, capable of sensing, processing, and communicating one or more vital signs, can be seamlessly integrated into wireless personal or body networks (WPANs or WBANs) for health monitoring. These networks promise to revolutionize health care by allowing inexpensive, non-invasive, continuous, ambulatory health monitoring with almost real-time updates of medical records via the Internet. Though a number of ongoing research efforts are focusing on various technical, economic, and social issues, many technical hurdles still need to be resolved in order to have flexible, reliable, secure, and power-efficient WBANs suitable for medical applications. This paper discusses implementation issues and describes the authors' prototype sensor network for health monitoring that utilizes off-the-shelf 802.15.4 compliant network nodes and custom-built motion and heart activity sensors. The paper presents system architecture and hardware and software organization, as well as the authors' solutions for time synchronization, power management, and on-chip signal processing.
