摘要

本文介绍了一种完整的射频到直流无线电力传输植入式整流天线系统。为简单起见,选择工业、科学和医疗波段(ISM 902.8-928 MHz)的外部半波偶极子作为来自人体外部的能量发射器。嵌入的圆形偶极天线接收能量,然后通过整流电路将其转换为直流电。详细讨论了系统的结构。最后,对不同外部天线与人体距离、不同嵌入深度和不同电路输入功率水平下的整流效率和整体系统效率进行了研究。

Implantable rectenna system for biomedical wireless applications
In this paper, a complete RF to DC wireless power transmission implantable rectenna system is presented. For simplicity, an external half-wave dipole at Industrial, Scientific and Medical bands (ISM 902.8-928 MHz) is selected as an energy emitter from outside human body. An embedded circular dipole antenna receives the energy and then converts it to DC power by a rectifying circuit. The structure of the system is discussed in details. Finally, the rectifying efficiency and the global system's efficiency are examined for different external antenna to human body distances, different embedded depth and various levels of circuit's input power.
