可穿戴健康和活动监测设备用于在出现健康问题时进行预防和早期干预。为了被广泛采用，这些设备必须舒适，易于使用，并提供有意义的，无错误的数据。本研究提出一种微型实时无线监测系统，能够采集三轴加速度，使用集成的加速度计，单导联心电图（ECG）和温度。嵌入式数据处理允许在设备上检测心率和身体位置，并可能基于阈值生成警报和警告。它是一种可穿戴设备，预期附着在患者胸部，并将采集和处理的数据传送到用于可视化、控制和进一步通信的移动的电话。我们专注于通过简化数据处理算法和优化通信协议来延长设备的使用寿命。通过与参考装置的比较，所提出的实验数据验证了所提出的系统的功能。此外，我们实验证明，在连续ECG采集和定期心率报告和16.6 mW的平均功耗为1.86 mW的完整的实时突发数据传输在0 dBm与丢失的数据包检索。
Wearable health and activity monitoring devices are used to enable prevention and early intervention in case of health problems. In order to be widely adopted, these devices must be comfortable, easy to use and provide meaningful, error-free data. This study presents a miniature real-time wireless monitoring system capable of acquiring tri-axis acceleration using an integrated accelerometer, one-lead electrocardiogram ( ECG) and temperature. Embedded data processing allows for on-device detection of heart rate and body position with a possibility of generating alarms and warnings based on thresholds. It is a wearable device, intended to be attached on a patient's chest and to communicate acquired and processed data to a mobile phone used for visualization, control and further communication. We focus on extending the lifetime of the device through simplification of data processing algorithms and optimization of communication protocols. Presented experimental data verify the functionality of the proposed system by comparing with reference devices. Furthermore, we experimentally prove average power consumption of 1.86 mW during continuous ECG acquisition and periodic heart rate reporting and 16.6 mW for complete real-time burst data transmission at 0 dBm with missing packet retrieval.
