摘要

我们分析了皮质植入物中从身体传输天线到1×1×1 mm3天线的无线链路中的功率和电压传输，为无电池脑机接口微电子系统提供功率和数据遥测。我们比较了常规、分段和倾斜发射环路天线的无线链路性能。此外，我们还分析了在植入天线中插入磁介电磁芯所获得的性能改进。并通过液头模型的测量验证了仿真模型的正确性。

Electromagnetic modelling and measurement of antennas for wireless brain-machine interface systems

We analyze the power and voltage transfer in a wireless link from an on-body transmit antenna to 1×1×1 mm3 antenna in a cortical implant to provide power and data telemetry for a battery-free brain-machine interface microelectronic system. We compare the wireless link performance with regular, segmented, and tilted transmit loop antennas. Moreover, we analyze the performance improvement achieved by inserting a magneto-dielectric core in the implant antenna. We also attest the simulation model through measurements in a liquid head phantom.
