Sensor devices ("motes") which integrate an embedded microprocessor, low-power radio and a limited amount of storage have the potential to significantly enhance the provision of emergency medical care. Wearable vital sign sensors can wirelessly monitor patient condition, alerting healthcare providers to changes in status while simultaneously delivering data to a backend archival system for longer-term storage. As part of the CodeBlue initiative at Harvard University, we previously developed a mote-based pulse oximetry module which gathers data from a noninvasive finger sensor and transmits it wirelessly to a base station. To expand the capabilities of the mote for healthcare applications we now introduce EKG on Mica2, the first custom-designed electrocardiograph sensor board to interface with this platform. We additionally present VitalEKG, a collection of software components which allow the capture and wireless transmission of heart activity traces. We present preliminary test results which validate our approach and suggest the feasibility of future enhancements.
集成了嵌入式微处理器、低功耗无线电和有限存储量的传感设备（“节点”）有潜力显著提升紧急医疗护理的水平。可穿戴生命体征传感器能够无线监测患者状况，在提醒医疗服务提供者患者状态变化的同时，还能将数据传送到后端存档系统进行长期存储。作为哈佛大学“蓝色代码”计划的一部分，我们之前开发了一个基于节点的脉搏血氧饱和度模块，该模块从无创手指传感器收集数据并将其无线传输到基站。为了扩展节点在医疗保健应用中的功能，我们现在推出了Mica2平台上的心电图（EKG），这是首个与该平台接口的定制设计心电图传感器板。我们还展示了VitalEKG，这是一组软件组件，可实现心脏活动轨迹的采集和无线传输。我们展示了初步测试结果，这些结果验证了我们的方法，并表明了未来改进的可行性。
