Biomedical implants require wireless power and bidirectional data transfer. We pursue our previous work on a novel topology for a multiple carrier inductive link by presenting the fabricated coils. We show that the coplanar geometry approach is better suited for displacement tolerance. We provide a theoretical analysis of the efficiency of power transfer and phase-shift-keying communications through an inductive link. An efficiency of up to 61% has been achieved experimentally for power transfer and a data rate of 4.16 Mb/s with a bit-error rate of less than 2 × 10(-6) has been obtained with our fabricated offset quadrature phase-shift keying modules due to the inductive link optimization presented in this paper.
生物医学植入物需要无线功率和双向数据传输。我们通过展示制造的线圈来延续我们之前关于多载波感应链路的新型拓扑结构的工作。我们表明共面几何结构方法更适合位移容限。我们通过感应链路对功率传输和相移键控通信的效率进行了理论分析。实验中实现了高达 61%的功率传输效率，并且由于本文提出的感应链路优化，我们制造的偏移正交相移键控模块获得了小于 2×10(-6)的误码率，数据传输速率达到 4.16 Mb/s。
