磁电天线（ME）可以在不同频率下展现无线能量收集和感测的双重能力。在这篇文章中，混合ME天线的行为电路模型进行了描述，以模拟电路仿真过程中的射频（RF）能量收集和检测操作。这项工作的ME天线与CMOS能量采集器芯片接口，以实现为完全集成的植入式设备开发无线通信链路的目标。集成系统的一个作用是从附近的发射器接收脉冲调制功率，另一个作用是感测和传输低幅度的神经信号。本文报道的测量结果是第一个结果，证明了用一个双模ME天线在两个不同频率下同时进行低频无线磁传感和高频无线能量收集。所提出的行为ME天线模型可用于能量收集电路的设计优化。执行测量以验证无线功率传输链路，其中具有2.57 GHz谐振频率的ME天线连接到以65 nm CMOS技术设计的能量采集器芯片。此外，该双模ME天线使得能够使用具有与第二63.63 MHz谐振模式匹配的频率的载波信号进行并发感测。已经开发了一个无线测试平台，用于评估ME天线作为神经植入物设计的工具，该原型系统被用来提供第一个实验结果与磁调制动作电位波形的传输。
A magnetoelectric antenna (ME) can exhibit the dual capabilities of wireless energy harvesting and sensing at different frequencies. In this article, a behavioral circuit model for hybrid ME antennas is described to emulate the radio frequency (RF) energy harvesting and sensing operations during circuit simulations. The ME antenna of this work is interfaced with a CMOS energy harvester chip towards the goal of developing a wireless communication link for fully integrated implantable devices. One role of the integrated system is to receive pulse-modulated power from a nearby transmitter, and another role is to sense and transmit low-magnitude neural signals. The measurements reported in this paper are the first results that demonstrate simultaneous low-frequency wireless magnetic sensing and high-frequency wireless energy harvesting at two different frequencies with one dual-mode ME antenna. The proposed behavioral ME antenna model can be utilized during design optimizations of energy harvesting circuits. Measurements were performed to validate the wireless power transfer link with an ME antenna having a 2.57 GHz resonance frequency connected to an energy harvester chip designed in 65nm CMOS technology. Furthermore, this dual-mode ME antenna enables concurrent sensing using a carrier signal with a frequency that matches the second 63.63 MHz resonance mode. A wireless test platform has been developed for evaluation of ME antennas as a tool for neural implant design, and this prototype system was utilized to provide first experimental results with the transmission of magnetically modulated action potential waveforms.
