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.
