In April 2022, I joined Kyushu University as a research student after being awarded the MEXT scholarship. In 2023, I advanced to a Ph.D. student. My research focuses on developing low-power data transfer circuits for biomedical implants and next-generation wireless communication systems using CMOS technology. Specifically, I work on designing energy-efficient circuits that enable reliable and high-speed data transmission while minimizing power consumption, which is crucial for implantable medical devices. Additionally, my research explores the integration of CMOS-based circuits with advanced metamaterial-based inductive channel designs, to enhance communication efficiency. Through this work, I aim to develop miniaturized, power-efficient systems that improve the performance and longevity of biomedical implants and wireless networks.
