Coupling Independent metamaterial-based wireless power and data transfer system over a single channel for biomedical applications

这项研究的目的是在单个通道上实现超材料辅助的无线功率和数据传输(WPDT)系统，以紧凑生物医学植入物。此外，该WPDT系统具有1-自由运行振荡器，以实现功率和数据的动态传输而不会由于发送器和接收器之间的耦合的改变而导致效率下降，以及2-基于CMOS技术的时钟和数据恢复电路，以恢复数据，而不需要在接收器侧增加紧凑性的任何时钟产生电路以及在低功率条件下的操作。在本牺牲年(FY2022)，自由运行振荡器和时钟和数据恢复的初始原型的设计和制造已经完成。时钟和数据恢复电路的结果已提交给国际会议。此外，自由运行振荡器的特性正在进行中。最后，在超材料辅助的无线能量传输系统的主题下，在一个国际会议上做了一次特邀演讲。此外，一篇论文已经发表在一份排名很高的Q1期刊上。

The purpose of this research is the implementation of a metamaterial-assisted wireless power and data transfer (WPDT) system over a single channel to compact biomedical implants. Also, this WPDT system features 1- a free running oscillator to enable dynamic transfer of the power and data without efficiency degradation due to the change in the coupling between the transmiter and receiver, and 2-a clock and data recovery circuit in CMOS technology to recover the data without the need for any clock generation cicuit in the reciever side that add to the compactness as well as the operation under low power conidition.In this ficial year (FY2022), the design and fabrication of intial prototypes of both free running oscillator and the clock and data recovery has been completed. The obtained results of the clock and data recovery circuit has been submitted to an international conference. Also, the characterization of the free running oscillator is under processing.Finally, under the topic of metamaterial-asisted wireless power transfer system, an invited lecture has been presented at an international conference. Moreover, a paper has been published on a highly ranked Q1 journal.
