In this paper, we propose a monitoring system that employs a passive RFID tag to transmit heart rate using an ECG signal as its source. This system operates without a battery and has been constructed with easily available commercial components. Here, an RFID tag is used as an on-off keying device, wherein it is normally transmitting, but turns off every time a heart beat is detected. Heart beats ranging from 30BPM through 300BPM are successfully measured using our device. It is shown that the system is capable of providing accurate heart rate measurements up to a distance of ten feet with a standard deviation of less than one beat per minute without a local power source. The proposed system is also found to be resilient in the presence of an additional RFID tag.
在本文中，我们提出了一种监测系统，该系统采用无源射频识别（RFID）标签，以心电图（ECG）信号为源来传输心率。该系统无需电池即可运行，并且由易于获得的商用组件构建而成。在此，一个RFID标签被用作开关键控设备，它通常处于发射状态，但每次检测到心跳时就会关闭。使用我们的设备成功测量了每分钟30次心跳至300次心跳的范围。结果表明，该系统在没有本地电源的情况下，能够在十英尺的距离内提供准确的心率测量，标准差小于每分钟一次心跳。还发现所提出的系统在存在额外RFID标签的情况下具有弹性。
