A portable, low-cost, and battery-powered wireless monitoring system that is capable of measuring multiple physiologic parameters simultaneously from many subjects was developed. The wireless communication of data is based on a commercially-available mote known as Tmote Sky. The star network topology (SNT), is used to collect data from many patients via multiple motes. Application protocol software was developed to facilitate the communication link between the monitor terminal and multiple motes. Based on the standard specifications of the mote, the SNT strategy, and the application protocol software design, a single mote can support up to 5 electrocardiogram signals with a sampling rate of 200 Hz. This capability facilitates affordable wireless monitoring of multiple physiologic signals from many subjects; its application is especially attractive for monitoring subjects in nursing homes, battlefields, and disaster scenarios.
开发了一种便携式、低成本且由电池供电的无线监测系统，该系统能够同时测量来自多个受试者的多种生理参数。数据的无线通信基于一种名为Tmote Sky的商用微控制器。星型网络拓扑结构（SNT）用于通过多个微控制器从许多患者收集数据。开发了应用协议软件以促进监测终端与多个微控制器之间的通信链路。基于微控制器的标准规格、SNT策略和应用协议软件设计，单个微控制器可以支持高达5个采样率为200 Hz的心电图信号。这种能力有助于对来自多个受试者的多种生理信号进行经济实惠的无线监测；其应用对于监测养老院、战场和灾难场景中的受试者特别有吸引力。
