This paper describes wireless wearable and ambient sensors that cooperate to monitor a person's vital signs such as heart rate and blood pressure during daily activities. Each wearable sensor is attached on different parts of the body. The wearable sensors require a high sampling rate and time synchronization to provide a precise analysis of the received signals. The trigger signal for synchronization is provided by the ambient sensors, which detect the user's presence. The Bluetooth and IEEE 802.15.4 wireless technologies are used for real-time sensing and time synchronization. Thus, this wearable health-monitoring sensor response is closely related to the context in which it is being used. Experimental results indicate that the system simultaneously provides information about the user's location and vital signs, and the synchronized wearable sensors successfully measures vital signs with a 1 ms resolution.
本文介绍了一种无线可穿戴和环境传感器，可在日常活动中合作监测人体的生命体征，如心率和血压。每个可穿戴传感器都贴在身体的不同部位。可穿戴传感器需要高采样率和时间同步，以提供对接收信号的精确分析。同步的触发信号由环境传感器提供，环境传感器检测用户的存在。蓝牙和 IEEE 802.15.4 无线技术用于实时感测和时间同步。因此，这种可穿戴健康监测传感器的响应与它所使用的环境密切相关。实验结果表明，该系统可以同时提供用户位置和生命体征的信息，并且同步的可穿戴传感器成功地以 1ms 的分辨率测量生命体征。
