摘要

为了提高植入式医疗器械的无线功率传输效率，提出了一种由磁电异质结构机械天线与射频感应线圈相结合的接收整流天线。接收天线工作在54 kHz，由一个30 × 10 × 0.456 mm3的ME天线和一个30 × 12 × 3mm3的60匝电感线圈线圈组成。对接收天线和发射天线进行了分析，并测量了无线功率传输性能。模拟了谐振频率下的比吸收率（SAR），以满足安全标准。在发射线圈与拟议接收天线之间15mm距离处，最终测量的PTE为2.8159%，大大高于单个ME天线或感应线圈的PTE。所提出的接收天线适用于无线生物医学设备。

Combined Magnetoelectric/Coil Receiving Antenna for Biomedical Wireless Power Transfer

To improve the wireless power transfer efficiency (PTE) of implantable medical devices (IMDs), a receiving rectenna consisting of a magneto-electric (ME) heterostructure mechanical antenna combined with an RF inductive coil is proposed in this paper. The receiving antenna, which operates at 54 kHz, consists of a ME antenna of 30 × 10 × 0.456 mm³ and a 60-turn inductive coil wound of 30 × 12 × 3 mm³. The receiving and transmitting antennas are analyzed and the wireless power transfer performance is measured. The specific absorption rate (SAR) at the resonant frequency is simulated to satisfy the safety standard. The final measured PTE at a distance of 15 mm between the transmitting coil and the proposed receiving antenna is 2.8159%, which is considerably higher than that of a single ME antenna or an inductive coil. The proposed receiving antenna is suitable for wireless biomedical devices.
