【Abstract】 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 30800235) 资助 基金项目: 国家自然科学基金( 60875061, 作者单位: 1 上海交通大学电子信息与电气工程学院医学精密工程 及智能系统研究所( 上海 200240) 2 杰升生物科技( 上海) 有限公司( 上海 200235) 作者简介: 郭子平( 1986—) ,男,硕士研究生。 E-mail: sunnyapi@ 163. com 通信作者: 刘华,副教授
