To reduce user burden and enhance aesthetics in diabetes management, we aim to develop a fully implantable glucose sensor using photovoltaic power transfer technology with ultra-miniature solar cells. This circuit design aims to improve the precision of digital conversion of glucose concentrations and enable wireless transmission. By utilizing electrochemical measurement and integrating the photovoltaic power transfer circuit with an integrating ADC, multiple glucose concentration measurements can be performed with a single power supply.
