We exhibit our ongoing R&D and proof-of-concept efforts for a Web3-based PHR application carried out with the Advanced Medical Engineering Informatics Consortium Endowed Research Division at the Global Center for Medical Engineering and Informatics, Osaka University (MEI Center). Visitors can explore project materials, view PoC demo videos, and gain a clearer understanding of how the system operates. We also welcome those interested in the effective utilization of next-generation medical and healthcare data or in joining future PoC activities.
