| Outline of Annual Research Achievements |
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 for dynamic transfer, and 2-a clock and data recovery circuit in CMOS technology with low power consumption.
In this ficial year (FY2023), final prototypes of the metamaterial-assisted free running oscillator and its characterization have been completed. Results has been drafted and submitted to an international Q1 journal.
Finally, under the topic of clock and data recovery, a presentation has been has been done at an international conference. Moreover, a paper has been published on a highly impacted Q1 journal (IEEE-TAP).

| Current Status of Research Progress |
Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
The planned test in phantom model has been performed early before and the results is submitted for review in an international journal.
|
| Strategy for Future Research Activity |
In FY2024, a new chip will be fabricated for the clock and data recovery circuit with lower power consumption. The obtained results will be summarized and published.
|
| Causes of Carryover |
The left over amount was a difference in a domestic trip fee. It will be used together with the assigned amount for the following year.
