生物遥测系统使用传感器，为连续远程监测人体生理参数提供物理、化学和生物数据。在其他应用中，生物遥测通过监测关键的生理参数，如心率、脉搏波形、呼吸频率、血氧饱和度、体内压、胃肠道化学参数或管腔可视化，应用于高危患者的监测。在20世纪50年代后期，无线通信技术开始被应用于测量内腔的pH值和温度，也被应用于皮下和植入部位的应用，尽管有一些限制(Farrar等人，1957年)。后来，在20世纪70年代，开发了几个系统，例如用于胎儿监测、心电遥测和胃肠压力监测的设备(Ko和Neuman，1967；Neuman等，1970；Ko等，1971)。惠普公司于1972年开发了便携式心电图机HP71800A，用于24小时心电监测。从那时起，已经开发了几种生物遥测设备。所有生物医学遥测应用的一个关键参数是传感操作，特别是可穿戴或可植入设备的能量馈送。其他挑战包括测量的大小、采样率和可靠性。这些传感器的硬件通常包括微控制器、超低功率射频收发器、天线、模拟信号调理电路、数据转换器和
Biotelemetry systems use sensors which provide physical, chemical, and biologi-cal data for the continuous remote monitoring of human physiological parameters. Among other applications, biotelemetry is applied for the monitoring of high-risk patients through the monitoring of crucial physiological parameters such as heart rate, pulse waveform, respiratory rate, blood oxygen saturation, intracorporal pressure, gastrointestinal chemical parameters, or lumen visualization. In the late 1950s wireless communication technologies began to be applied for measuring the pH and the temperature from internal cavities and also for applications involving subcuta-neous and implantable sites, though with several limitations (Farrar et al., 1957). Later, during the 1970s, several systems were developed, such as devices for fetal monitoring, electrocardiogram telemetry, and gastrointestinal pressure monitoring (Ko and Neuman, 1967; Neuman et al., 1970; Ko et al., 1971). Hewlett Packard devel-oped a portable electrocardiograph in 1972, the HP71800A, for ECG monitoring on a 24-h basis. Since then, several biotelemetry devices have been developed. A critical parameter for all the biomedical telemetry applications is the sensing operation and especially the power feed of the wearable or implantable device. Other challenges include the size, the sampling rate, and the reliability of measurements. The hardware of these sensors usually comprises a microcontroller, an ultralow-power RF transceiver, antennas, analog signal conditioning circuitry, data converters, and
