摘要：

目的为长期连续监测动物生理参数，设计并实现了一种基于无线能量传输技术的植入式遥测系统。方法系统由无线能量传输设备、植入式微型电子胶囊、数据记录仪、数据处理软件组成。胶囊尺寸为13.06 mm×30.90 mm，重6.38 g，功耗约150 mW。结果模拟实验验证了该植入式遥测系统能够监测心电、体温和血压。选用新西兰兔进行活体实验，测得体温范围为37.2～37.3℃，基线噪声为0.1℃，血压范围为74～83 mmHg，基线噪声为3 mmHg。结论模拟实验和动物活体实验证明基于无线能量传输技术的植入式动物生理参数遥测系统能够比较准确地监测动物的心电、体温和血压等参数。

Objective An implantable radio-telemetry system based on wireless power transmission technology is designed for long-term monitoring animal physiological parameters continuously.Methods The system contains wireless power transmission device，implantable miniature electronic capsule，data logger and data processing software.The capsule is only  13.06 mm×30.90 mm in size and weights 6.38 g with approximately 150 mW power consumption.Results The simulation experiment proves that the system is able to detect ECG，body temperature and blood pressure.One New Zealand rabbit is used in the vivo experiment，the detected body temperature is from 37.2℃ to 37.3℃ with 0.1℃ baseline noise and the detected blood pressure is from 74 mmHg to 83 mmHg with 3 mmHg baseline noise.Conclusions The proposed implantable radio-telemetry system，which is used for monitoring the animal physiological parameters based on wireless power transmission technology，is able to monitor the electrocardiograph (ECG)，body temperature and blood pressure of animals.
