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

本研究的目的是在单一通道上实现超材料辅助无线电源和数据传输（WPDT）系统，以紧凑的生物医学植入物。此外，该WPDT系统具有1-自由运行振荡器，使功率和数据能够动态传输，而不会因发送端和接收器之间耦合的变化而降低效率；2-a时钟和数据恢复电路采用CMOS技术，无需在接收端使用任何时钟产生电路即可恢复数据，从而增加了紧凑性以及低功耗条件下的运行。在这个正式的年份（2022财年），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研究成果已提交给一个国际会议。同时，自由运行振荡器的特性也在研究中。最后，以“超材料辅助无线电力传输系统”为主题，在国际会议上做了特邀报告。并在排名较高的Q1期刊上发表论文。

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.
